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
Disagree, the fractions are unequal and 10/15=66% while 15/20=75%
6x=-5y
-5y=6x
so the answer is y=-6/5x
Answer
Step-by-step explanation:
Okay so add 276 two times, then divide that answer by 400.
