Y=-x+5
-x+5=1/3x-3
-x+8=1/3x
8=4/3x
6=x
y=-6+5
y=-1
C.
Answer:
7x - 3 = 60

x = 9
if you need to find for y
11y + 5 = 60
11y = 55
y = 5

Answer:
(f+g)(x) = x^2 +10x +7
Step-by-step explanation:
(f+g)(x) = f(x) +g(x) = (15x +7) +(x^2 -5x)
= x^2 +x(15 -5) +7
= x^2 +10x +7
Answer: Ellen's house is farther away by 898 feet.
Step-by-step explanation:
Given: The distance between Haley's house and Ellen's house = 1.41 miles
We know that 1 mile = 5,280 feet
Then, 
The distance between Haley's house and Dirk's house = 6,547 feet
Clearly, 6,547<7,444.8
And 
Therefore, Ellen's house is farther away by 898 feet.
