Answer:
<h2><u>
FALSE</u></h2>
Step-by-step explanation:
To find the slope you need to pick two points. Points (2,4) and (4,3) are the points I used. (It does not really matter what points you chose). Now we have to follow the formula to find the slope. The formula can be seen below
Slope (m) = ΔY/ΔX
Now solve
ΔX = 4 – 2 = 2
ΔY = 3 – 4 = -1
Once you have solved it, you take it and make it a fraction
-1/2 = -0.5
To find f(-20), first figure out which piece x = -20 fits with.
Since -20 < -12, x = -20 first in the domain used by the third piece.
For f(-20), treat this function as if it was just f(x) = 3x-7.
f(-20) = 3(-20) -7
= -60 - 7
= -67

Answer:
10.45
Step-by-step explanation:
To solve it without the calculator:
First, you multiply 4.75 times 0.2 (0.95)
Then you multiply 4.75 times 2 (9.5)
Then you add the 2 numbers to get the answer.
0.95 + 9.5 = 10.45
With the calculator, just put in the 2 numbers and click enter!
