Step-by-step explanation:
8k -2z = 16
to solve for k let's add 2z both sides
8k = 16+2z
divide both sides of the equation by 8
8k/8= 16+2z/8
k= 16+2Z /8
It would be: 2 / 5/8
We can re-write it as: 2 * 8/5 = 16/5
So, your final is 16/5 or 3.2

Answer:
30
Step-by-step explanation:
Average rate of change=Δf(x)/Δx = [f(x2)-f(x1]/[x2-x1]
Δf(x)/Δx = [f(5)-f(1]/[5-1]
f(5)=5³-5=120
f(1)=1³-1=0
Δf(x)/Δx = [120-0]/[5-1]=120/4=30
