So you can solve it and what ever answer you get is the ordered pair like the answer is 4/5 so go right 4 and go up 5 and that is your answer
The answer is inches
Step 1. Subtract length of the door from the width of the door:
Step 2. You want the same space to be on each side of the bar. So, divide the difference from step 1 by 2:
So let's simplify the equation first.
9x + 12 - 5 = ax + b
9x + 7 = ax + b
9x - ax - b = 7
Alright now plug in the numbers for each option.
I don't feel like doing all of them but I did A (one solution) and B (no solution because the two 9x's cancel out).
Answer:
A
Step-by-step explanation:
A) irrational number only
