Answer: The temperature, y, increases 5/4 or 1.25 degrees per minute, x.
(0,-10) (8,0)
use y1-y2/x1-x2 to find the slope
-10-0/0-8
= -10/-8
= 5/4
The answer is 2. 5 minutes, because you do 15 minutes - 10 minutes to find the difference. I open this helps!
ANSWER
Scale factor is 1.25
The dilation is an enlargement.
EXPLANATION
Let the scale factor of the dilation be k, then

We divide both sides by 5 to get,

This implies that,

Since the scale factor is more than one, the dilation is an enlargement.
Answer:
Step-by-step explanation:
lets say you are paying for a year
A- it would cost you $30 on the spot and another 60 for the year
A=30$60= $90
A-$30+($5*t)
B- it will cost you $20 on the spot then another 120 for the year
B-$20+($10*t)
B=$20+$120= $140
t= 12
