Answer:c is the correct answer
Step-by-step explanation:
A repair company's charge for repairing a certain type of copy machine fits the model y = 47.38 + 0.617x
where y is the number of dollars charged and
x is the number of minutes the repair person is on the job.
Therefore, to determine the number of minutes that it would take for the cost of repair to reach $130, we would substitute y =130 into the given model. It becomes
130 = 47.38 + 0.617x
0.617x = 130 - 47.38 = 82.62
x = 82.62/0.617 = 134 minutes
Answer:
Step-by-step explanation:
-D/9>4, multiply each side by -9 (and reverse sign because of multiplication by a negative)
D<-36
Answer:
6x+2y
Step-by-step explanation:
Solving 4x +3y +2x -y eqn, we get
6x+2y

Answer:
the answer is -3 because -3 is closer to 0 than -4
Answer:
x = 1.33 I think.
Step-by-step explanation:
First you would write out your problem
Next you would take away 6 from both sides to get 4 = 3x
Now you would divide both sides by three to get x = 1.33
