Answer: 
Step-by-step explanation:
The slope of the line is

Using the point (-2, 0) to substitute into point-slope form, we get the equation to be 
Answer:
a =9
b= 28
Step-by-step explanation:
The parts of the ratio must be equal
5:7:a = 20:b:36
How do we get from 5 to 20
We multiply by 4
So multiply the first by 4
5*4:7*4:a*4 = 20:b:36
Ratio 1
5*4 =20 true
Ratio 2
7*4 =b
28 = b
Ratio 3
4a = 36
Divide by 4
4a/4 = 36/4
a = 9
Answer:
The answer will be b &c
Step-by-step explanation:
Because it is equivalent to 16:6
100/95= 1.05. Each question worth 1.1 rounded. You could miss 19 but if you miss 20 you go under 80.
Isolate the variable by dividing each side by factors that don't contain the variable.
