The answer is -4. I solved it on a calculator and got -4
Answer:
B.
Step-by-step explanation:
B.
- 9 ≤ - 3x - 6 ≤ 6
1 part.
- 9 +6 ≤ - 3x - 6 +6
- 3/(- 3) ≤ - 3x/(- 3)
1 ≥ x
2d part
- 3x - 6 +6≤ 6 + 6
- 3x ≤ 12
- 3x/(-3) ≥ 12/(-3)
x ≥ - 4
x ≥ - 4 and x≤ 1
The formula you can use is
y - y1 = m(x - x1)
plug the y value you are given into y1 and the x value you are given into x1. m is for your slope value. after you plug in the known values, solve. your final answer should be in standard form which is
Ax + By = C
your answer should not contain any fractions and your Ax value cannot be a negative value, By and C can be negative though.
hope this helps :)
