Answer:

Step-by-step explanation:

rise = y₂ - y₁ = -1 - (-10) = -1 + 10 = 9
run = x₂ - x₁ = 9 - (-4) = 9 + 4 = 13

Answer:
x=9 y=0 (9,0)
Step-by-step explanation:
A = s2 (Area of a square is its side squared)
P = 4s (perimeter of a square is a side times 4)
A = 324 (the area of this square is 324 ft2)
fencing = $7 per foot
Let's find the side through the area. Find the root:
√324 = √s2
18 = s
Now the perimeter:
P = 4 * 18 = 72
Now to find how much the fencing will cost:
72 * 7 = 504
78 is the correct answer.
Answer:
0
Step-by-step explanation:
2x-x+7 = x+3+4
2x-x-x = -7+3+4
2x-2x = -4+4
0 = 0
