Answer:
C
Step-by-step explanation:
f(x)=72-4x
72-4x=0
4x=72
x=18
f(x)<=18

Answer: 35 (choice C)</h3>
=============================================
Explanation:
For any triangle, the three interior angles always add to 180.
D+E+F = 180
(7b+1) + (2b+1) + (b+8) = 180
(7b+2b+b) + (1+1+8) = 180
10b+10 = 180
10b = 180-10
10b = 170
b = 170/10
b = 17
Use this value of b to find the three angle measures
- D = 7b+1 = 7*17+1 = 119+1 = 120
- E = 2b+1 = 2*17+1 = 34+1 = 35 degrees
- F = b+8 = 17+8 = 25
As a check,
D+E+F = 120+35+25 = 120+60 = 180
which helps confirm the correct answers.

Answer:
The actual dimensions of the kitchen are 
by 
Step-by-step explanation:
step 1
Find the scale of the drawing
To find the scale , remember that is equal to the ratio of the corresponding dimension in the drawing divided by the corresponding actual dimension
so
step 2
To find the actual dimensions of the kitchen, divide the dimension in the drawing by the scale
so
3.
1000 miles per month.
12 months in a year.
1000 × 12 = 12000 miles per year
Oil change every 4000 miles.
12000 ÷ 4000 = 3
Therefore 3 oil changes per year.
