Proportion A
 The first thing you should know in this case is what the rate of change means.
 The rate of change in a linear equation is given by the slope of the line.
 For a linear equation, the rate of change is constant.
 So we have to:
 y = 9x
 The slope is:
 m = 9
 Proportion B
 The slope of the line will be:
 m = (y2-y1) / (x2-x1)
 Substituting values:
 m = (57.5-34.5) / (5-3)
 m = 11.5
 Answer:
 The rate of change in proportion A is 2.5 less than in proportion B.

mars1129 [50]

Answer: C

Step-by-step explanation: In this problem, we're given a function

in the form of a chart and we're asked to find the inverse of the function.

To find the inverse of a function, we simply switch

the x and y values in each point.

In other words, the point (-1, -2) becomes (-2, -1),

the point (0, 3) becomes (3, 0), the point (1, 8) becomes (8, 1),

and the point (2, 13) becomes (13, 2).

What is x equal to? 4(4-3x)=4
inysia [295]

4(4 - 3x) = 4      <em>divide both sides by 4</em>

4 - 3x = 1     <em>subtract 4 from both sides</em>

-3x = -3     <em>divide both sides by (-3)</em>

<h3>x = 1</h3>
