Answer:
5
Step-by-step explanation:
-4w+7=-10w+37
+10w +10w
=============
6w+ 7=37
-7 -7
==========
6w=30
/6 /6
w=5
Just find the slope between the points
basically find (f(10)-f(7))/(10-7)
f(7)=7^2-3(7)-4=49-21-4=24
f(10)=10^2-3(10)-4=100-30-4=66
slope=(66-24)/(10-7)=42/3=14
average rate of change is 14
8x+3=43
-3 -3
8x=40
/8 /8
X=5
