1. 2y = 4 -x = -3 what is the solution to this system of equations? a) (2, 3) b) (-3, 2) c) (3, 2) d) (-3, 4) 2. 2x - y = 5 3x + 2y = 4 solve the system of equations. a) (3, 1) b) (0, 2) c) (2, -1) d) (9/7, 17/7)

1. C, 2.C

Step-by-step explanation:

Here's why for the first one it's easy because we just solve y=2, x=3, so we select C, the next one however we have to know eliminate a variable, which in this case we can eliminate the y variable quite easily. So once we did that we got x=2, now we plug that in to the first equation and we get -y=1, which is equal to -1.

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

step-by-step explanation:

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
