Answer:
86.1yd
Step-by-step explanation:
area of a triangle= base*height/2
21*8.2=172.2
172.2/2=86.1
X + 17 +3x -15
x +3x = 4x
17-15 = 2
which becomes 4x +2 so it is true
Answer:
Yes! :)
Step-by-step explanation:
-18 - 25z - 30 - 35z = -48 - 60z = 12(-4 - 5z)
-72 - 60z + 24 = -48 - 60z = 12(-4 - 5z)
D because domain is always the x values range is always the y values and for this graph the line stops at 0 and doesn't go any higher so the domain is all the numbers lower than 0
The function is

.
This means that as we get from 1 to 2, we have the following values:

, and

.
Similarly, if we check x=3, we have

.
We can see that as x changes by 1 (with greater values), y increases by a factor of 12.
Answer: multiply by 12
