To calculate the slope of a line you need only two points from that line, (x1, y1) and (x2, y2). The equation used to calculate the slope from two points is: On a graph, this can be represented as: There are three steps in calculating the slope of a straight line when you are not given its equation.
Answer:
2x²y+(x²y-2xy²) = 3x²y-2xy²
(5xy²-x²y) +3x²y = 5xy²-2x²y
4x²y+(x²y+xy²) = 5x²y+xy²
x²y+(-2xy²-4x²y) = -3x²y-2xy²
Step-by-step explanation: there you go
Answer:
The answer is A: True
Step-by-step explanation:
Repeating decimals are rational numbers because there is only one number that's repeating over and over again.

Answer: x = 15 ; y = 2
Step-by-step explanation:
x + y = 17
x - y = 13
x + y = 17
x = 17 - y
17 - y - y = 13
17 - 2*y = 13
- 2*y = 13 - 17
- 2*y = -4
y = -4 / -2
y = 2
x + y = 17
x + 2 = 17
x = 17 - 2
x = 15
Answer:
I got $9.65 but you could just pick the closest to that
