Answer:

y = 4x + 36

Step-by-step explanation:

To find the equation in slope-intercept form, rearrange to isolate "y".

Slope-intercept form is y = mx + b. The variables mean:

"x" and "y" - points that are on the line, or solutions.

"m" - the slope, how steep the line is

"b" - the y-intercept, when the line touches the y-axis

Isolate "y".

8x - 2y = -72

8x - 8x - 2y = -72 - 8x        Subtract 8x from both sides.

-2y = -72 - 8x        Left side : 8x - 8x = 0

[tex]\frac{-2}{-2}y = \frac{-72}{-2} - \frac{8}{-2}x[/tex]        Divide both sides by -2

y = 36 - (-4)x        Simplify the fractions

y = 36 + 4x        Remember two negatives make a positive, add 4x.

y = 4x + 36        Put "4x" in front of 36. It looks like y = mx + b now.

"m" would be 4.

"b" would be 36.

To figure out which value of y makes this true, plug in each option:

y = 8

25 - y < 15       Plug in 8 for y

25 - 8 < 15

17 < 15      This is false because 17 is not less than 15

y = 9

25 - y < 15     Plug in 9 for y

25 - 9 < 15

16 < 15     This is false because 16 is not less than 15

y = 10

25 - y < 15       Plug in 10 for y

25 - 10 < 15

15 < 15    This is false because 15 can't be less than itself (15)

y = 11

25 - y < 15     Plug in 11 for y

25 - 11 < 15

14 < 15       This is true because 14 is less than 15

700 children attended the fair

Solution:

Let "a" be the number of children attended

Let "b" be the number of adults attended

Cost for each children = $ 1.50

Cost for each adult = $ 4

1000 adults attended the fair

b = 1000

One certain day $5050 is collected. Therefore, we frame a equation as:

number of children attended x Cost for each children + number of adults attended x Cost for each adult = 5050

[tex]a \times 1.50 + 1000 \times 4 = 5050\\\\1.5a + 4000 = 5050\\\\1.5a = 5050 - 4000\\\\1.5a = 1050\\\\Divide\ both\ sides\ by\ 1.5\\\\a = 700[/tex]

Thus 700 children attended the fair

24 hours

24 hours is the solution to 300=10(2)^t/15

After 24 hours the scientist expect to have 300 bacteria cells.

Given :

the number of cells to be given by the formula, where t is the number of hours since the experiment started.

[tex]C=100(2)^{\frac{t}{15} }[/tex]

't' represents the time taken for the cells to grow.

we need to find out the time taken to have 300 bacteria cells.

So, we replace C with 300 and solve for t

[tex]C=100(2)^{\frac{t}{15} }\\300=100(2)^{\frac{t}{15} }\\\frac{100\cdot \:2^{\frac{t}{15}}}{100}=\frac{300}{100}\\2^{\frac{t}{15}}=3\\\frac{t}{15}\ln \left(2\right)=\ln \left(3\right)\\t=\frac{15\ln \left(3\right)}{\ln \left(2\right)}\\t=23.77443[/tex]

So, it takes 24 hours to have 300 bacteria cells.

In an isosceles triangle with a base of 7 units, the two other sides have to be greater than 3.5 units but less than 7 units due to the triangle inequality theorem, which means each side must always be shorter than the sum of the other two sides.

An isosceles triangle is a triangle with two sides of equal length. If the base of the triangle is 7 units, the lengths of the other sides could be any value greater than 3.5 units but less than 7 units. This principle is rooted in the triangle inequality theorem which states that any side of a triangle always needs to be shorter than the sum of the other two sides.

So in this case, since the base is 7 units, the other two equal sides (let's call them 'a' and 'b') could be, for example, 5 units each, but don't forget they must fulfill two conditions: firstly, 'a' + 'b' > 7  (which is true if both 'a' and 'b' are more than 3.5 units), and secondly, 'a' + 7 > 'b' as well as 'b' + 7 > 'a' (which are true as long as 'a' and 'b' are less than 7 units). Consequently, both 'a' and 'b' could be a range of lengths, but they must be greater than 3.5 units and less than 7 units in order to ensure that the triangle inequality theorem is respected.

What are Alternate Angles ?

These angles are located on the inner side of the parallel lines and on opposite sides of the transversal. Alternate angles are equal.

To solve, equate both values;

4x - 5 = 2x + 9

4x - 2x = 9 + 5

2x = 14

x = 14 / 2

x = 7

The value of x is 7

Answer:

i) angle 3 is 120°

ii) angle 3 + angle 4  = 180°  as both angles make up a staright line

    ∴  angle 4  = 180° - angle 3  = 180° - 120° = 60°

iii) angle 6 = angle 3  = 120°   as they are opposite interior angles

iv) angle 6 + angle 8  = 180°  as both angles make up a straight line  

   ∴  angle 8  = 180° - angle 6  = 180° - 120° = 60°

Step-by-step explanation:

i) angle 3 is 120°

ii) angle 3 + angle 4  = 180°  as both angles make up a staright line

    ∴  angle 4  = 180° - angle 3  = 180° - 120° = 60°

iii) angle 6 = angle 3  = 120°   as they are opposite interior angles

iv) angle 6 + angle 8  = 180°  as both angles make up a straight line  

   ∴  angle 8  = 180° - angle 6  = 180° - 120° = 60°

If the function f(x) = mx + b has an inverse function, which statement must be true?

a) m=/0

b)  m = 0

c) b=/0

d )  b = 0

Answer:

The value of [tex]m[/tex] cannot be equal to 0. In other words,

[tex]m\:\ne \:0[/tex]

Step-by-step explanation:

Considering the function

[tex]f(x) = mx + b[/tex]

Lets find the inverse of this function.

Suppose

Lets exchange the variables [tex]x[/tex] and [tex]y[/tex] such as

[tex]x=my+b[/tex]

Lets isolate the variable [tex]y[/tex]

[tex]my=x-b[/tex]

[tex]y=\frac{x-b}{m}[/tex]

Suppose

[tex]f\left(x\right)^{-1}=y[/tex]

As

[tex]y=\frac{x-b}{m}[/tex]

So, inverse function is

[tex]f\left(x\right)^{-1}=\frac{x-b}{m}[/tex]

As the denominator [tex]m[/tex] cannot be zero in the inverse function.

Thus, the value of [tex]m[/tex] cannot be equal to 0. In other words,

[tex]m\:\ne \:0[/tex]

Step-by-step explanation:

Edge 2020

(1) ∠ABC = 65°, ∠DBE = 65°, ∠CBE = 115°, ∠ABD = 115°

(2) ∠ABC = 62°, ∠DBE = 62°, ∠CBE = 118°, ∠ABD = 118°

Solution:

(1) In the given image ABC and DBE are vertical angles.

Vertical angle theorem:

If two angles are vertical then they are congruent.

⇒ ∠ABC = ∠DBE

⇒ 3x° + 38° = 5x° + 20°

Arrange like terms one side.

⇒ 38° – 20° = 5x° – 3x°

⇒ 18° = 2x°

⇒ x° = 9°

∠ABC = 3(9°) + 38° = 65°

∠DBE = 5(9°) + 20° = 65°

Adjacent angles in a straight line = 180°

⇒ ∠ABC + ∠CBE = 180°

⇒ 65° + ∠CBE = 180°

⇒ ∠CBE = 115°

∠ABD and ∠CBE are vertical angles.

∠ABD = 115°

(2) In the given image ABC and DBE are vertical angles.

⇒ ∠ABC = ∠DBE

⇒ 4x° + 2° = 5x° – 13°

Arrange like terms one side.

⇒ 13° + 2° = 5x° – 4x°

⇒ 15° = x°

∠ABC = (4(15°) + 2°) = 62°

∠DBE = 5(15°) – 13° = 62°

Adjacent angles in a straight line = 180°

⇒ ∠ABC + ∠CBE = 180°

⇒ 62° + ∠CBE = 180°

⇒ ∠CBE = 118°

∠ABD and ∠CBE are vertical angles.

∠ABD = 118°

[tex]-45x+12-12<112-12\\-45x<100[/tex]

Now, we will divide both sides by -45

[tex]\frac{-45x}{-45}<\frac{100}{-45}\\\\x<-\frac{100}{45}\\\\x<-\frac{20}{5}[/tex]

The solution to the given inequality is [tex]x<-\frac{20}{9}[/tex].

Lee sold 60 magazine

Step-by-step explanation:

Terrence and Lee were selling magazines for a charity

We need to find how many magazines Lee sold

Assume that Lee sold x magazines

∵ Terrance sold 30% more than Lee in the first week

∵ Lee sold x magazines in the first week

- Find 30% of x and add it to x to find how many magazines

  Terrance sold

∵ Terrance sold = 30% × x + x

∴ Terrance sold = [tex]\frac{30}{100}[/tex] × x + x = 0.3 x + x

∴ Terrance sold = 1.3 x magazines in the first week

∵ Terrance sold 12 magazines in the second week

- Add 1.3 x to 12 to find the number of magazines that Terrence

  sold in the two weeks

∴ Terrence sold 1.3 x + 12 magazines in the two weeks

∵ Lee did not sell any in the next week

∴ Lee sold x magazines in the two weeks

∵ Terrance sold 50% more than Lee by the end of the 2nd week

- Equate 1.3 x + 12 by the sum of x and 50% of x

∴ 1.3 x + 12 = 50% × x + x

∵ 50% × x = [tex]\frac{50}{100}[/tex] × x = 0.5 x

∴ 1.3 x + 12 = 0.5 x + x

- Add the like terms in the right hand side

∴ 1.3 x + 12 = 1.5 x

- Subtract 1.3 x from both sides

∴ 12 = 0.2 x

- Divide both sides by 0.2

∴ 60 = x

therefore

The scale factor of the smaller rectangle to the larger rectangle is 3/2

The rate of cheese is $9.5 per kilogram which does not match Lydia's estimation.

The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.

Lydia decides to provide cheddar cheese for the competition. She buys 4.2 kilograms for 39.90.

She estimates the cost of 1 kilogram of cheese to be $1.

Let's check the rate of cheese. Then we have

Rate = $39.90 / 4.2

Rate = $9.5 per kilogram

The rate of cheese is $9.5 per kilogram which does not match Lydia's estimation.
