They, together, can paint 12 houses in 35 days. To get a single house, we only have to calculate

which is very close to 3 (a bit below)
Answer:
<h2>-25b + 101</h2>
Step-by-step explanation:

The answer is A because the perpendicular slope is the opposite reciprocal which would be positive x.
Answer:
4/3
Step-by-step explanation:
A proportional relationship is a relationship that crosses through the origin or (0,0). This means the slope of the line can be found by subtracting the points (12,16) and (0,0) in the slope formula.

So the slope is 4/3 and must be the value between any two points on the line.
This means the function moves from (0,0) to (1, 4/3).
Start with

Divide both sides by -3

If the absolute value of a number is 4, that number can either be 4 or -4: we have the two solutions
