Answer:
a. Chart (attached)
b. and c. graph attached
Step-by-step explanation:
a. We use the equation given to us and plug in the values of "x" that have been shown to find the corresponding values of y.
So, when x=0, 
when x=20, 
when x=40, 
b. The graph has been shown in a similar manner. All the three points of part a are connected to form the straight line y=6.75x+25. So, we have (0,25), (20,160) and (40, 295)
c. The y axis is the earnings in dollars and the x axis is the number of hours worked.
Answer:
4
Step-by-step explanation:
First, use the distributive property: 2x+16=4x+8
Second, move +8 to the other side(and turn it negative): 2x+8= 4x
Do the same for +2x: 8=2x
divide both sides by 2: 4=x
The standard form of a linear equation is:

A and B are integers
C is a constant
Then, of the given equation the next are writen in standard form:
Answer:
I don't get it. Is that the full question?
Answer:
15.7 - 2a
Step-by-step explanation:
Perimeter = 15.7 inches
2a + b = 15.7
b = 15.7 - 2a
