(2x - y = 4
8x + y = -9
solutions to the equation?

x= , y = -5

Step-by-step explanation:

Given:

Equation 1:

Equation 2:

Adding Equation 1 and 2 we get

Now Substituting value of x= in Equation 1 we get

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
