What is the solution set of -9x
2 answers:
Answer:
B. x≥-3
Step-by-step explanation:
To solve this problem, first you have to isolate it one one side of the equation.
First, multiply -1 from both sides.
(-9x)(-1)≥27(-1)
Solve.
27*-1=-27
9x≥-27
Next, divide by 9 from both sides.
9x/9≥-27/9
Then, solve.
-27/9=-3
Therefore, the correct answer is x≥-3.
For this case we must find the solution of the following inequality:

If we divide by -9 on both sides of the inequality we have:

If we divide by -1 on both sides of the inequality, the sense of it changes:

Slope intercept form
y = mx + b:
10 = 7x + 3
y = 10
slope (m) = 7
b = 3
standard form:
Ax + By + C:
7x + 10y + 3
A = 7
B = 10
C = 3
