Answer:

y = [tex]\frac{1}{8}[/tex] x - 3

Step-by-step explanation:

Use the midpoint formula

Given (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

[ [tex]\frac{1}{2}[/tex] (x₁ + x₂ ), [tex]\frac{1}{2}[/tex] (y₁ + y₂ ) ]

Here (x₁, y₁ ) = (7, 3) and (x₂, y₂ ) = (9, - 7), thus

midpoint = [ [tex]\frac{1}{2}[/tex] (7 + 9), [tex]\frac{1}{2}[/tex] (3 - 7 ) ] = (8, - 2)

-----------------------------------------------------------

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Rearrange 5x - 6 = 2y into this form by dividing all terms by 2

y = [tex]\frac{5}{2}[/tex] x - 3 ← in slope- intercept form

with y- intercept c = - 3 ⇒ (0, - 3 )

-------------------------------------------------------------

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂, x₁ )

with (x₁, y₁ ) = (8, - 2) and (x₂, y₂ ) = (0, - 3)

m = [tex]\frac{-3+2}{0-8}[/tex] = [tex]\frac{-1}{-8}[/tex] = [tex]\frac{1}{8}[/tex]

y = [tex]\frac{1}{8}[/tex] x - 3 ← equation of line

Slope is defined as (y2-y1)/(x2-x1)

"A" gives a slope of (10-6)/(-4-(-1))=4/-3=-4/3

Hope this helped

The point pair establishing a line with a slope of -4/3 is  (-1, 6) and (-4, 10). which is the correct answer would be an option (A).

The slope of a line is defined as the gradient of the line.

To determine the slope of a line, we can use the formula: slope m = (y₂ - y₁)/(x₂ -x₁ )

Using this formula, we can calculate the slope for each of the pairs of points given:

A) (-1, 6) and (-4, 10):

slope = (10 - 6)/(-4 - (-1)) = -4/3

B) (6, -1) and (-4, 10):

slope = (10 - (-1))/(-4 - 6) = -11/10

C) (-1, 6) and (10, -4):

slope = (-4 - 6)/(10 - (-1)) = -10/11

D) (6, -1) and (10, -4):

slope = (-4 - (-1))/(10 - 6) = -3/4

Therefore, the pair of points that defines a line with a slope of -4/3 is (-1, 6) and (-4, 10).

Answer:

79716.98

Step-by-step explanation:

Answer:

formula for sum of interior angles is (n-2)*180 - for a regular polygon

divide that by the number of sides

so 6-2 = 4*180 =720 degrees

720/6 = one angle(angle a) =120

Answer:

D. 120 degrees.

Step-by-step explanation:

We nee to find the measure of the interior angle in a regular hexagon.

The exterior angle = 360 / 6 = 60 degrees.  ( In all convex polygons the sum of the exterior angles = 360 degrees).

So α = 180 - 60 = 120 degrees    (adjacent angles add up to 180 degrees).

Answer:m=-11

Step-by-step explanation:

You find the answer by dividing 187 by -17.

The value for m is -11

According to the BODMAS rule, the brackets have to be solved first followed by powers or roots (i.e. of), then Division, Multiplication, Addition, and at the end Subtraction. Solving any expression is considered correct only if the BODMAS rule or the PEMDAS rule is followed to solve it.

Given here: -17m=187

Thus simplifying we get m= 187/-17

                                            = -11

Hence, The value for m is -11

Can be solved with no different solution

Your equation is unclear. Do you mean the following:

(15x+21)/3=5x+7 or 3(15x+21)=5x+7

If the left equation is the correct one, the left side simplifies to 5x+7=5x+7, which must mean all real numbers are correct solutions. Thus, it has infinite real solutions.

The equation (15x + 21)³ = 5x + 7 is a cubic equation. The number of solutions can be 0, 1, 2, or 3 solutions.

The equation is (15x + 21)³ = 5x + 7. To determine the number of solutions, we need to simplify and solve the equation.
Step 1: Expand the equation using the binomial theorem. This gives us: 3375x³ + 14175x² + 19305x + 9261 = 5x + 7.
Step 2: Combine like terms on both sides of the equation. This results in: 3375x³ + 14175x² + 19305x + 9254 = 0.
Step 3: This is a cubic equation. Cubic equations can have 3 solutions at most. However, it is not guaranteed that this equation will have 3 solutions. It can have fewer solutions or even no real solutions.
Therefore, the number of solutions for this equation is either 0, 1, 2, or 3 solutions. Further analysis or calculations may be needed to determine the exact number of solutions.

The probability that in a sample of 12 customers at Noodles & Company restaurant, none of them will order a nonalcoholic beverage is 0.020211.

In this question, we are given that the probability that a customer will order a nonalcoholic beverage at Noodles & Company restaurant is 0.48. We are asked to find the probability that in a sample of 12 customers, none of them will order a nonalcoholic beverage.

To find the probability that none of the 12 customers will order a nonalcoholic beverage, we can use the concept of independent events and the multiplication rule of probability.

The probability that a customer will order a nonalcoholic beverage is 0.48, so the probability that a customer will not order a nonalcoholic beverage is 1 - 0.48 = 0.52. Since each customer's decision is independent, the probability that none of the 12 customers will order a nonalcoholic beverage is (0.52)^12 = 0.020211.

From given,

Final solution is 260 liter

Let x be the liters of 40 % dye solution

Then, (260 - x) is the liters of 53 % dye solution

Therefore, according to question,

x liters of 40 % dye solution is mixed with (260 - x) liters of 53 % dye solution to get 260 liters of 50 % dye solution

40 % of x + 53 % of (260 - x) = 50 % of 260

Solve for "x"

[tex]\frac{40}{100} \times x + \frac{53}{100} \times (260-x) = \frac{50}{100} \times 260\\\\0.4x+ 0.53(260-x) = 0.5 \times 260\\\\0.4x + 137.8 - 0.53x = 130\\\\0.13x = 137.8 - 130\\\\0.13x = 7.8\\\\Divide\ both\ sides\ by\ 0.13\\\\x = 60[/tex]

Thus 60 liters of 40 % dye solution is used

Then, (260 - x) = 260 - 60 = 200

Thus 200 liters of 53 % dye solution is used
