Answer: 77 CD’s

Step by step:
Since we are writing a proportion it will look like this .....
33/1.5 = x/3.5 ( 33 over 1.5 and x over 3.5)

Now that we have our proportion , you cross multiply.....
33 x 3.5 = 115.5
“X” x 1.5 = 1.5x
So now you will have an equation that looks like this....... 1.5x=115.5
Once you have that then you divide 1.5 from each side , then after that then you should have x=77
So it takes 77 CD’s to be in a 3.5 inch high stack .
Hoped this helped , if it didn’t I apologize
Good luck

Write an equation in slope intercept form for the linear equation f(-4) = 2 and f(6) = -3
AlladinOne [14]

Answer: y= -2.5x+12

Step-by-step explanation:

<u>Skills used:</u>

  1. Finding slope from two points
  2. Finding y-intercept from two points or a slope
  3. Writing equations in slope-intercept form

<u>Steps:</u>

  1. Write out the two equations as points: (-4, 2) and (6, -3)
  2. Find the slope by using the equation: \frac{y_2-y_1}{x_2-x_1}, which gives us -5/2, or -2.5 (I'm going to use decimals)
  3. Write it into slope intercept form: y= -2.5x+b
  4. Substitute a point into y and x: 2= -2.5(4)+b
  5. Solve to get b= 12
  6. Put it into the full equation: y=-2.5x+12

Answer: y = 3x - 2

the equation is y = ax + b  (a ≠ 0)

see in the picture, the line passes through  (0;-2) and (2;4)

because the line passes through  (0;-2) => b = -2

               the line passes through (2;4) => 2a + b = 4

have: b = -2

          2a + b = 4

⇔ a = 3

    b = -2

=> the equation is y = 3x - 2
