Answer:
(-2, 4)
Step-by-step explanation:
y = -3x - 2
y = -x +2
=> -3x - 2 = -x +2
-3x + x = 2 + 2
-2x = 4
x = -2
-x + 2 = y
2 + 2 = y
4 = y
Answer: ? = x + 1
Step-by-step explanation:
The perimeter of the garden is x + 3x + 1 + x + ?
The perimeter of the garden is also (6x + 2)
Therfore:
x + 3x + 1 + x + ? = 6x + 2
<em>Collect like terms: </em>
5x + 1 + ? = 6x + 2
<em>Subtract 5x from both sides:</em>
1 + ? = x + 2
<em>Subtract 1 from both sides:</em>
? = x + 1
You cannot find ? as a number, only in terms of x.
