Use substitution...
x-2(2x-3.5)=-14
x-4x+7=-14
-3x=-21
x=7
Plug in x into one of the equations to get y...
y=2(7)-3.5
y=10.5
(7,10.5)

Answer:
B. (x, y) --> (x, y + 5)
Step-by-step explanation:
Y is up and down
X is left and right
So assuming that Y is north she needs to go 5 units up Y
(x, y + 5) = (x, 5y)
1) Width=4.7 2) Length=18.4
Answer:
28 < x < 114
Step-by-step explanation:
- x cannot be larger than or even equal to 71 + 43 = 114. So it must be less than 114.
- But there are limits on the other end as well. 43 +x > 71, otherwise you won't have a triangle. so you have to solve that inequality as well
- 43 + x > 71 Subtract 43 from both sides.
- 43-43 + x > 71 - 43
- x > 28
- To put this in the form of the answer you need it looks like this.
- 28 < x < 114
