Answer:
8
Step-by-step explanation:
approx. 8
As 510 lies closer to the cube of 8 which is 512
Answer:
A
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [a, b ] is
Here [ a, b ] = [ 2, 6 ], thus
f(b) = f(6) = - 
+ 70 = - 64 + 70 = 6
f(a) = f(2) = - 2² + 70 = - 4 + 70 = 66
average rate of change = 
= 
= - 15 → A
elimination means to get rid of one variable by altering the coefficients of variable (by multiplying and diving by some constant number)
in this case, if you just add the two equation, y gets cancelled you get 5x=20 or x=4
put it in any equation to get y (this works because both lines pass through the same point, so they must satisfy that point) to get y=2
