Answer:
You need to find the equations for each scenario and set them = to each other
Step-by-step explanation:
A) S = 5t + 5
B) S = 7t + 2
Now set them = and solve for t
5t + 5 = 7t + 2
3 = 2t
t = 3/2 of an hr
To check plug in 3/2 into both equations and you should get same answer.

f(-2) is the x value, fond the Y value of the graphed line when the line is at x -2.
The line is at Y = 2
The answer is B.
H+20=35-4H
first, combine your like terms, which are the Hs
add the 4H to both sides, and you will get
5H+20=35
now subtract 20 from both sides, that will cancel out the 20 on the left and leave you with
5H=15
finally, divide both sides by 5 and you will get H=3.

Answer:
<h3>5 feet</h3>
Step-by-step explanation:
The set up will give a right angles triangle with:
length of the ladder as the hypotenuse h = 13 foot
The distance from the base of the house to the top of the ladder is the opposite side (y) = 12 feet
The distance of the base of the ladder from the base of the house wil be the adjacent side (x)
Using the pythagoras theorem to get x:
h² = x²+y²
13² = x²+12²
x² = 13²-12²
x² = 169 -144
x² = 25
x = √25
x = 5 feet
Hence the distance of the base of the ladder from the base of the house is 5 feet long
