Answer:

x=16, y=-12. (16, -12).

Step-by-step explanation:

5x-16y=272

y=(64-7x)/4

------------------

4y=64-7x

4y+7x=64

5x-16y=272

---------------------

4(4y+7x)=4(64)

5x-16y=272

-----------------

16y+28x=256

5x-16y=272

------------------

33x=528

x=528/33

x=16

5(16)-16y=272

80-16y=272

16y=80-272

16y=-192

y=-192/16

y=-12

Answer:

Step-by-step explanation:

G(x) exceeds f(x) from x = 0 to x = 3.

Then we see that f(x) is 11 at x = 4 and g(x) is 10 at x = 4, so there is an intersection between these 2 points.

After this f(x) far exceeds g(x).
