Solve the system of equations.
-5x+2y=9 y=7x
Help!

x = 1

y = 7

Step-by-step explanation:

Given

-5x + 2y = 9

y = 7x

Substitute 7x for y in the first equation.

We have,

-5x + 2(7x) = 9

-5x + 14x = 9

9x = 9

Divide both sides by 9

9x/9 = 9/9

x = 1

Substitute 1 for x In either of the above equations to get y.

Using the second equation,

We have

y = 7x

Therefore

y = 7 x 1

y = 7

x = 1 and

y = 7

been looking for the answer havent been able to find it   but good luck with it

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to
