The increase in temperature is 
Step-by-step explanation:
we know that
The formula to calculate the rate or slope between two points is equal to

we have

Substitute the values


therefore
The increase in temperature is 
Answer:
7 x 9 = 63, 63 divided by 2 = 31.5,
31.5 x 4 = 126
9 x 9 = 81
Add given areas:
126 + 81 = 207 in2 is your answer
A) -2, -1
(solve the second equation for x (subtract 2y to the other side, then divide by 2 so x=-y-3) then plug that equation into the x value of the first equation to get y=-1; plug y=-1 into the second equation to get x=-2)
Answer:
Step-by-step explanation:
<u>Substitute:</u>
<u>Then the expression becomes:</u>
The result is 1 regardless the value of x other than 1.
"b" represents the population of bobcats.
1) "t" represents the number of years after 2008.
2) The domain (t) starts at 0 (which is the year 2008) ⇒ t ≥ 0
3) The range (b) starts when t = 0. b =-0.32(0)² + 2.7(0) + 253 ⇒ b ≥ 253
4) The graph is discrete because the population must be in whole numbers.
