B. because the slope is negative 5 so it can't be a or d. the y-interept can't be one because it is 11.
12 - 2(7x - 3) = 3(1-2x) - 5x
12 - 14x + 6 = 3 - 6x - 5x
-14x + 6x + 5x = 3 - 12 - 6
-3x = -15
x = -15/-3
x = 5
Answer:
7
Step-by-step explanation:
The length of AB is the distance between A and B which is B-A -> 13-6= 7
The first thing we are going to do for this case is define variables.
We have then:
x: number of gallons of water
y: total weight
We then have an equation of the form:

Where,

Substituting values:

We choose an ordered pair:

Substituting values:

Answer:
y = 8.34x + 30
