Answer:

x = - 1, y = 4

Step-by-step explanation:

A. We are going to use elimination method because we have +2y and -2y, and when we add these equations +2y and -2y are going to be eliminated.

x + 2y = 7

4x = - 4

x = - 1

x + 2y = 7

-1 + 2y = 7

2y = 8

y = 4

What is the average rate of change of the function f(x) = 5x ^ 2 + 20x between x = 0 and x = 0.5

Vitek1552 [10]

Answer:

22.5

Step-by-step explanation:

The average rate of change on the interval [a, b] is the ratio ...

(f(b) -f(x))/(b -a)

For your function and interval, it is ...

(f(0.5) -f(0))/(0.5 -0)

Since f(0) = 0, this reduces to ...

average rate of change = 2·f(0.5) = 2(5(0.5)² +20(0.5)) = 2(5/4 +10)

average rate of change = 22.5
