Answer: <span>y - 37.5 = 2.5 ( x - 7)
Explanation:
1) The point-slope form is has this form:
y - y1 = m (x - x1)
Where m is the slope or rate of change and x1, y1 are the coordinates of the point.
2) you are told that the the rate of change of water (m) is 2.5
m = 2.5
3) The point is given by that after 7 min the rain barrel contains 37.5 gallons. This is:
x1 = 7
y1 = 37.5
</span>4) Replace those value in the point-slope model:
y - 37.5 = 2.5 ( x - 7)
That is the point-slope model or equation.

Step-by-step explanation:
Answer:
3
Step-by-step explanation:
write the question in an algebraic way:
3x+6 = 6x - 3
Solve:
6x-3 = 3x+6
6x - 3 - 3x = 6
3x = 9
x = 3
Hope this helps.
Good Luck
Answer:
Teo= 9
Richard= 24
Step-by-step explanation:
x= Richard
y= Teo
33-15= 18
18÷2= 9
15+9=24
