Answer:
C
Step-by-step explanation:
If you simplify the equation you get
. To solve a square root function, you need to set up
. You can take the square root of both sides to get
. Then, we identify the intervals that will satisfy the equation, which is -3 ≤ x < 1.
Sorry if the explanation is kind of confusing, I wasn't sure how to describe it.
Answer:
circle it?
Step-by-step explanation:
°
X + y = 16 (1)
x/y = 3 (2)
-------
x + y = 16
x = 16 - y
1. Substitute x into equation 2
16-y/y = 3
16 - y = 3y
16 = 4y
y = 4
2. Now substitute y into equation 1
x/y = 3
x/4 = 2
x = 12
Therefore, x = 12, y = 4
Answer: x = 9
