Q:

Which of the following is not a way to represent the solution of the inequality 8x - (5x + 4) >= -31?x >= -9-9 <= xA number line with a closed circle on -9 and shading to the leftA number line with a closed circle on -9 and shading to the right

Accepted Solution

A:
Answer:-9<=x A number line with a closed circle on the -9 and shading to the left.Step-by-step explanation:This is because when you solve the problem:8x-(5x+4)>=-31Step 1: (distribute the negative sign)  8x-5x-4>=-31Step 2: (Subtract 5x from 8x)  3x-4>=-31Step 3: (Add 4 to both sides of the equation)  3x>=-31+4 which equals 3x>=-27Step 4: (Divide by 3 into both sides of the equation)  x>=-9 You should graph the answer with a closed circle on -9 and shading to the right because x>=-9 states that x is greater than or equal to 9. (When you shade to the right the numbers are increasing).Hope this helps :)!
