School A has 480 students and 16 classrooms. School B has 192 students and 12 classrooms.

boyakko [2]

Answer:96

Step-by-step explanation:

A; 480/16 = 30 students per classroom

B: 192/12 =16 students per classroom

we need x such that $\frac{480-x}{16} = \frac{192+x}{12}$

which means

(480-x )* 12 should be equal to (192+x) * 16

5,760 - 12x = 3,072+16x

5,760 - 3,072 = 12x + 16x

2,688 = 28x

x = 96

4. Which of the following functions has a rate of change that stays the same?

BaLLatris [955]

Answer:

$y=-4x+10$

Step-by-step explanation:

A linear function has a constant rate of change.

So all you need to do is to identify which of the given options is a linear function.

$y=-4x+10$ is a linear function and the rate of change is -4.

We can see this is a constant.

$y=\frac{1}{2}x^2$ has a variable rate of change which is $x$

$y=3^x$ also has a rate of change which is $3^x\ln3$

$y=x^2+2$ also has a variable rate of change which is 2x
