Let x represent some number
Sum of 3 and twice some number = 3 +2x
Five times the sum of 3 and twice some number: 5(3+2x)
5(3+2x)=70
15+10x=70
Subtract 15 from both sides to have 10x by itself
10x=55
Divide 10 on both sides to get x by itself
x=55/10
x=5.5

Step 1: Find the slope:
This gives you , but we need to find b.
To find b, substitute in one (x,y) pair and it doesn't matter which one. I'll go with (4,-2):
Now take that b-value and plug in into the slope-intercept form:
It's always a good idea to toss in the other x-value from the other point, to make sure it checks out.

Answer:
D. y=2x-2
Step-by-step explanation:
The format for the equation of a line is y=mx+b, where m is the slope and b is the y-intercept of the line.
The slope of this line is 2
The y-intercept of this line is -2
Therefore, the equation for this line should look like y=2x-2

Answer:
144 ft^2
Step-by-step explanation:
It is the same as the area of a single triangle with a base of 18 ft and a height of 16 ft. The formula is ...
A = (1/2)bh
= (1/2)(18 ft)(16 ft) = 144 ft^2
The shaded area is 144 ft^2.
