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:
B) x < 7
Step-by-step explanation:
−8x + 40 > −16
Subtract 40 from each side
−8x + 40-40 > −16-40
-8x > -56
Divide each side by -8, remembering to flip the inequality
-8x/-8 < -56/-8
x <7
Q (-1,-2) that is your answer.
$16x.15=$2.40
16+2.4=18.40 the answer is $18.40
Hopefully this is helpful.
Answer:
5 hours 3 minutes
Step-by-step explanation:
Add all of the times together, but remember that minutes only goes up to 60 minutes. So when you add all the minutes and you get 63, subtract 60 and add an hour, and you are left with 3 minutes.
