x- quarters
y - dimes
z- nickels

The system of equations would be
x+10=y
z+5=x
x+y+z= 4.75

Which is the best estimate for the average rate of change for the quadratic function graph on the interval 0 ≤ x ≤ 4?

tatuchka [14]

Answer:

The best estimate for the average rate of change is $-2$

Step-by-step explanation:

we know that

the average rate of change using the graph is equal to

$\frac{f(b)-f(a)}{b-a}$

In this problem we have

$f(a)=f(0)=0$

$f(b)=f(4)=-8$

$a=0$

$b=4$

Substitute

$\frac{-8-0}{4-0}=-2$

If f(x) = 8 – 10x and g(x) = 5x + 4, what is the value of (fg)(-2)?

Shkiper50 [21]

Answer:

Step-by-step explanation:

I'm going to assume you meant "what is the value of f(g(-2))?"

g(-2) = 5(-2) + 4 = -6

f(-6) = 8 - 10(-6) = 68
