Answer:

( 1 , 1 )

Step-by-step explanation:

2x + y = 3

x = 2y - 1

(You already have x so substitute x back into 2x + y = 3)

2(2y - 1) + y = 3

4y - 2 + y = 3

5y - 2 = 3

(Add -2 to both sides)

5y = 5

(Divide each side by 5 to isolate x)

y = 1

(Plug y into x = 2y - 1 to find x)

x = 2(1) - 1

x = 2 - 1

x = 1

The table shows the values of a function f(x).
QveST [7]

Answer:

The average rate of change is =-4

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is given by;

=\frac{f(b)-f(a)}{b-a}

We want to find the average rate of change of the function represented in the table  from x=-2 to x=2.

=\frac{f(2)-f(-2)}{2--2}

From the table f(-2)=25 and f(2)=9

The average rate of change from x=-2 to x=2 is

=\frac{9-25}{2--2}

=\frac{-16}{4}

=-4
