M: cost per hour
b: initial charge fee
x: hours (h)
To make both company to charge the same amount:
12x+376=15x+280
376-280=15x-12x
96=3x
X=32
So it took 32 hour to 2 company charge the same amount.
The cost gonna be: 12.(32)+376=760$

Answer:
27.2 cm
Step-by-step explanation:
14 cm / 2.5 = 5.6 cm, and
20 cm / 2.5 = 8 cm.
Then the new perimeter would be P = 2L + 2W, or, in this case:
P = 2(8 cm) + 2(5.6 cm) = 27.2 cm
Answer:
D
Step-by-step explanation:
Ngl I was confused for a minute. But domain is asking for the x-values and range is asking for the y-values.
You can see the points on the graph are (-4,1), (-2,2), (0, 3), and (2,4).
Because it is asking for the domain, it is asking for the X VALUES of the points you have found above. So the answer is {-4, -2, 0, 2}
So none of those answers look quite right
The reason I picked D is because it is the only one that contains the x values we picked. The rest have numbers outside the domain, such as 3, 4, 5, etc.
