Answer:
Step-by-step explanation:
2x^2+14x=520
x^2+7x-260
x(x+7)=260
so x=13
13x20=260
second
x^2+10x=875
x(x+10)=875
x= 25
25x35=875
Since there are 4 quarts in one gallon, there should be 20 quarts in 5 gallons. He is using a 1 quart container so he would have to fill it up 20 times, and empty it 20 times.
Answer:
Step-by-step explanation:
(2 - 3)/(4 - 0) = -1/4
y - 2 = -1/4(x - 4)
y - 2 = -1/4x + 1
y = -1/4x + 3
Answer: If you are solving for x, the answer would be...
2x-f(x)=9
Step-by-step explanation: Solve for x by simplifying both sides of the equation, then isolating the variable.

Answer:
A point (a, b) rotated around a point (x, y) 180 degrees will transform to point (-(a - x) + x, -(b - y) + y). A point (a, b) rotated around the origin 270 degrees will transform to point (b - y + x, -(a - x) + y).
