Answer: 51
Step-by-step explanation: (sqrt(2))^2 + 7^2
The squareroot and square cancel, leaving 2. 7^2=7*7=49
49+2=51
22.5 (shower) = X (variable used in place of the amount of water she uses to wash clothes) - 7.5 (the amount she used in the shower is 7.5 gallons less than she uses for washing clothes)
22.5 = X - 7.5 《 This is the equation.
Solve is by adding 7.5 to both sides to cancel out the negative 7.5 and you get (X = 30).
LINE A
y-intercept : 3
x-intercept: 3
Rate of change: x (because 3/3 equals 1 and 1 times x is the same as x by itself)
Line B
y-intercept: 2
x intercept: -2
rate of change : x (because 1/1 is 1 and 1 times x is the same as x by itself)
Line C
y-intercept: -4
x intercept: 2
rate of change: 2
Line A: Equation F
Line B: Equation D
Line C: Equation E
Extra Notes:
y=mx + b is the slope intercept equation.
M is the slope
B is the y intercept
X and Y are the coordinates
To find slope, you can always use y2-y1/x2-x1 or even determine the slope on the graph by using rise over run and simplifying when possible.

The simplest form is 15/28
Correct me if I'm wrong. Hope this helps!
1 and 1/8 miles. 1/3 is 3/8 of a mile. This 3/3 is 9/8 miles
