Answer:

1

Step-by-step explanation:

f(x) = x^2 - 2x - 4

when x = -1, f(-1) = (-1)^2 - 2(-1) - 4 = 1 + 2 - 4 = -1

when x = 4, f(4) = (4)^2 - 2(4) - 4 = 16 - 8 - 4 = 4

The average rate of change from x = -1 to x = 4:

  f(4) - f(-1)          4 - (-1)              5

---------------- = -----------------=   --------  = 1

 x4 - x1               4 - (-1)              5

Answer

The average rate of change = 1

Your friend is trying to see if you can guess the two numbers she secretly has written on her paper. Your friend tells you that
DaniilM [7]

Hello,

First we work out the equations:

x + y =62 will be the first equation.

2x= y +13 is the second equation.

We can first rewrite the second equation as 2x – y =13.

So we have:

x + y = 62

2x –y =13

KEEP IN MIND: With y being positive in one of the equations and negative in the other, we can combine the equations to quickly eliminate y and solve for x.

x + y = 62

+2x –y =13

3x = 75 divide both sides by 3 to get x.

x = 25

Now that we have x we can substitute the value for x, 25.

25 + y = 62 we can subtract 25 from both sides to get y.

y = 62- 25

y = 37

2(25) = 37 + 13

Therefore,

50 = 50

Have a amazing day.
