You can use substitution or elimination method to solve. <em>I used substitution.</em>

2(1/2y + 5) + 3y = -14

y + 10 + 3y = -14

4y + 10 = -14

4y = -24

y = -6

x = 1/2y + 5 = 1/2(-6) + 5 = -3 + 5 = 2

x = 2, y = -6

Answer: A

Hello,

6 - (-3) = 9

-7 - 5 = -12

$\sqrt{9^{2} +(-12)^{2} } = \sqrt{81 + 144} = \sqrt{225} = \sqrt{15^{2} } = 15$

Solve by elimination:<br> 4x+9y=28<br> -4x-y=-28

nikdorinn [45]

Step-by-step explanation:

4x+9y=28

-4x-y=-28

8y=0

divide both side by 8

y=0

solve for X in equation 1

4(X)-9(0)=28

4x-0=28

4x =28

divide both side by 4

4x/4=28/4

X= 7

y=0,x=7

Answer:

231

Step-by-step explanation:

because the whole circle has an area of 360 so on the right side there is half and a little more so you would cut it in half so you have 180 and on the right side you still have a little left so thats about 10 so now you have 190 then you add 21 +20 you have 41 +190 =231 hope this helps
