Answer:

y axis over x axis is the right answer

Answer:

Rise is 2 run is -1.  Slope is [tex]-\frac{2}{1}[/tex].

Why? Because adding any number and its opposite is always going to be zero.

Consider adding the number 5 to its opposite -5

5 + (-5) = 5-5 = 0

The same applies to fractions as well. All we do is change the sign from negative to positive, or vice versa, to get the opposite number. The opposites cancel out more or less.

You can think of it as going up 5 floors (positive 5), then going back down 5 floors (negative 5). So overall you didn't change floors at all (represented by 0)

Answer:

34

Step-by-step explanation:

We know that the sum of angles in a quadrilateral must be 360.

As such, we can sum up all given values for all 4 angles and set it equal to 360

[tex]360=108+88+2x+(3x-6)\\360=190+5x\\170=5x\\x=34\\\\[/tex]

Answer:

x=59

Step-by-step explanation:

the sum is 360 degrees.. Therefor

x + x + 2x + 3 + 2x + 3 = 360

combine alike terms

6x + 6 = 360

6x = 354

x = 59

Answer: 14 feet

Step-by-step explanation:

The formula for finding the area of a triangle is given as :

Area = [tex]\frac{1}{2}[/tex] x base x height

Let the height be h , then the base is 5 times the height , that is the base is 5h.

Substituting into the formula , we have

490 = [tex]\frac{1}{2}[/tex] x h x 5h

490 = [tex]\frac{1}{2}[/tex] x [tex]5h^{2}[/tex]

multiply through by 2

980 = [tex]5h^{2}[/tex]

divide through by 5

196 = [tex]h^{2}[/tex]

Therefore :

h = 14

Therefore : the height is 14 feet

The equations which have exactly one solution are:

Choice C: [tex]58x+52=78x-78[/tex]

Choice D: [tex]58x+52=-78x-78[/tex]

Explanation:

Choice A: [tex]-78x+52=-52x-78[/tex]

Adding both sides by 52x, we have,

[tex]-26x+52=-78[/tex]

Subtracting both sides by 52,

[tex]-26x=-130[/tex]

Dividing both sides by -26,

[tex]x=5[/tex]

Hence, the equation [tex]-78x+52=-52x-78[/tex] has exactly one solution.

Thus, Choice A is the correct answer.

Choice B: [tex]52 x+52=52 x-78[/tex]

Subtracting both sides by 52x,

[tex]52=-78[/tex]

Since, both sides are not equal.

It has no solution.

Thus, Option B is not the correct answer.

Choice C: [tex]58x+52=78x-78[/tex]

Subtracting both sides by 78x,

[tex]-20x+52=-78[/tex]

Subtracting both sides by 52,

[tex]-20 x=-130[/tex]

Dividing both sides by -20,

[tex]x=6.5[/tex]

Hence, the equation [tex]58x+52=78x-78[/tex] has exactly one solution.

Thus, Choice C is the correct answer.

Option D: [tex]58x+52=-78x-78[/tex]

Adding both sides by 78x,

[tex]136x+52=-78[/tex]

Subtracting both sides by 52,

[tex]136x=-130[/tex]

Dividing both sides by 136,

[tex]x=-\frac{65}{68}\\x=-0.956[/tex]

Hence, the equation [tex]58x+52=-78x-78[/tex] has exactly one solution.

Thus, Choice D is the correct answer.

Answer:

(4, 12)

Step-by-step explanation:

When the two lines intersect on a graph, it is when you can put the same value for "x" into both equations, and the same value for "y" into both equations.

Because they both equal "y", and y = y, you can equate the expressions together.

y = y

2x + 4 = 2.50x + 2

Now the goal is to move all the numbers with "x" to the left. Move the the numbers to the right side. (This is called isolating "x" because it will be alone).

2x + 4 - 4 = 2.50x + 2 - 4            Subtract 4 from both sides

2x = 2.50x - 2            

2x - 2.50x = 2.50x - 2.50x - 2            Subtract 2.50x from both sides

-0.50x = -2            

-0.50x/-0.50 = -2/-0.50            Divide both sides by -0.50

x = 4            Found "x" coordinate

Choose one of the original equations. Change "x" to 4 (called substitution).

y = 2x + 4

y = 2(4) + 4            Multiply first

y = 8 + 4            Add

y = 12            Found "y" coordinate

Now write the coordinates like an ordered pair (x, y).

The lines intersect at (4, 12).

Question:

A shopper bought a watermelon, a pack of napkins, and some paper plates. In his state, there is no tax on food. The tax rate on non-food items is 5%. The total for the three items he bought was $8.25 before tax, and he paid $0.19 in tax. How much did the watermelon cost?

Answer:

Cost of watermelon is $ 4.45

Solution:

From given,

Total amount for three items before tax = $ 8.25

Tax amount = $ 0.19

Tax on non food = 5 %

Here, non food means napkin and paper plates

Let "x" be the cost spent for napkin and paper plates

Then,

5 % = 0.19

100 % = x

This forms a proportion

[tex]5 \times x = 0.19 \times 100\\\\5x = 19\\\\x = 3.8[/tex]

Thus cost spent for napkin and paper plates is $ 3.8

Therefore,

Watermelon cost = total amount before tax - cost spent for napkin and paper plates

Watermelon cost = 8.25 - 3.8 = 4.45

Thus cost of watermelon is $ 4.45

The watermelon cost $4.45, calculated by subtracting the cost of the non-food items ($3.80) taxed at 5% from the total cost before tax ($8.25).

The information provided gives us the total cost before tax ($8.25) and the total tax amount ($0.19). Because only non-food items are taxed, and the tax rate is 5%, we can find the cost of the non-food items by dividing the total tax amount by the tax rate (expressed as a decimal).

Convert tax rate to decimal: 5% = 0.05

Divide the total tax by the tax rate: $0.19 / 0.05 = $3.80

Deduct the cost of the non-food items from the total cost before tax: $8.25 - $3.80 = $4.45

The cost of the watermelon, which is a food item and thus not taxed, is $4.45.

Answer:

Expression = 25

Step-by-step explanation:

2xy+2x^2 = ?

2(-2.5)(-7.5)+2(-2.5)^2 = ?

37.5 + (-12.5) = ?

= 25

Final answer:

The value of the expression 2xy + 2x² for x=-2.5 and y=-7.5 is 50.

Explanation:

To find the value of the expression 2xy + 2x² for x=-2.5 and y=-7.5, we substitute these values into the expression:

2(-2.5)(-7.5) + 2(-2.5)²

Simplifying this expression, we get:

(7.5) + 2(6.25)

= 37.5 + 12.5

= 50

Therefore, the value of the expression 2xy + 2x² for x=-2.5 and y=-7.5 is 50.

Step-by-step explanation:

(15+6d) - 2 + (-502 - 18 + 60)

(13+6d) + (-460)

6d + 13 - 460

6d - 447

The required answer is 6d - 531

Simplification generally means finding an answer for the complex calculation that may involve numbers on division, multiplication, square roots, cube  roots, plus and minus.

Now the given expression is,

(15 +6d - (2) + (-502 - 18 + 60)

Thus,

(15 +6d - (2) + (-502 - 18 + 60)

= 15 + 6d - 2 - 502 + 18 - 60

Rearranging we get,

= 15 + 18 + 6d - 2 - 502 - 60

= 33 + 6d - 564

= 6d - 564 + 33

= 6d - 531

this is the required answer.

Thus, the required answer is 6d - 531.

Step-by-step explanation:

The length of the rectangle is 87.1 feet

The area of the rectangle is the product of the length and width of a given rectangle.

The area of the rectangle = length × Width

We are given that a rectangular yard has a width that is 1/2 times its length and an area of 3800 square feet.

Length = L

Width = W

Given that

W = 1/2 L

Area =  3800 square feet

The area of the rectangle = length × Width

3800 = L x 1/2 L

L² = 7600

L = 87.1 feet

Answer:

Enough water has been poured .

Step-by-step explanation:

The garden needed water in a week = 5 liters

Jacob poured water on Monday = 326 ml = ( 326/ 1000) liters = 0.326 liters.

SEAN poured water on Tuesday = 1.5 liters

Gavin poured water on Wednesday = 2312 ml = ( 2312/ 1000) = 2.312 liters.

Stephen poured water on Thursday = 894 ml = ( 894/ 1000)  = 0.894 liters

The total amount of water poured by all these people = 0.326 + 1.5 +2.312 +0. 894 = 5.032 liters

Here we can see that water has been poured is more than the water required  in a week.

After converting all the water measurements to milliliters and summing them up, the garden received 5.032 liters of water over four days, which is slightly above the required 5 liters per week. Thus, the garden received enough water.

The question asks if the garden outside Ms. Mertz's class received enough water over a week. To determine this, we need to add up the amounts of water poured each day and compare it to the required 5 liters per week.

First, we convert all measurements to the same unit (milliliters). Then we sum up all the amounts:

326 ml (Monday) + 1500 ml (Tuesday) + 2312 ml (Wednesday) + 894 ml (Thursday) = 5032 ml

Since 1 liter = 1000 milliliters, we divide 5032 ml by 1000 to convert to liters:

5032 ml = 5.032 liters

The garden received 5.032 liters over the four days, which is just above the required 5 liters of water per week.

Therefore, the garden has received enough water for the week, with a small excess of 32 ml.

2(2x) + 1x = 40 or 4x + 1x = 40 is the result of combining by substitution

Solution:

Given that we have to combine 2y + 1x = 40 and y = 2x using substitution method

The substitution method for solving systems of equations involves expressing one variable in terms of another, thus removing one variable from an equation.

Given equations are:

2y + 1x = 40 -------- eqn 1

y = 2x ----------- eqn 2

We can substitute eqn 2 in eqn 1

Which means, substitute y = 2x in place of y in eqn 1

2(2x) + 1x = 40

4x + 1x = 40

5x = 40

x = 8

From eqn 2,

y = 2(8)

y = 16

Answer:

The new area of the triangle is (1 / 9) th of the original area.

That is to say the original area of the triangle is decreased to (1/9) th of its value.

Step-by-step explanation:

The area of a triangle is given by, Area = 1/2 [tex]\times[/tex] base  [tex]\times[/tex]  height

If each side of a triangle is cut to 1/3 of its original size then the base will also become one third and the height will also become one third.

Therefore the new area  will be given by  = 1/2  [tex]\times[/tex] (1/3 [tex]\times[/tex] base)  [tex]\times[/tex]  (1/3  [tex]\times[/tex] height)

   = 1/9  [tex]\times[/tex] 1/2  [tex]\times[/tex] base  [tex]\times[/tex] height

   = 1/9  [tex]\times[/tex] Area.

The new area of the triangle is 1 / 9 th of the original area.

When the sides of a triangle are reduced to 1/3 of their original size, the area of the triangle becomes 1/9 of its original area.

When the length of each side of a triangle is cut to 1/3 of its original size, the area of the triangle is affected by the square of the scale factor applied to the sides.

Let's use some mathematics to understand why this happens. The area of a triangle is given by the formula:

A = 1/2 * base * height, where 'base' represents the base of the triangle and 'height' represents the height of the triangle.

If each side of the triangle is reduced to 1/3 of its original size, both the base and the height will become 1/3 of their respective original sizes.

The new area (A') can be calculated as follows:

Simplifying this:

A' = 1/2 * (base * height) * (1/3 * 1/3)

A' = 1/2 * base * height * 1/9

A' = (1/2 * base * height) * 1/9

A' = A * 1/9

Therefore, the area of the triangle becomes 1/9 of its original area.
