Steps
Step 1: For each (x,y) point calculate x2 and xy.
Step 2: Sum all x, y, x2 and xy, which gives us Σx, Σy, Σx2 and Σxy (Σ means "sum up")
Step 3: Calculate Slope m:
m = N Σ(xy) − Σx Σy N Σ(x2) − (Σx)2
Step 4: Calculate Intercept b:
b = Σy − m Σx N.
Step 5: Assemble the equation of a line.
Answer:
x = 6
Step-by-step explanation:
because we know the lines intersect we also know the 2 angles are vertical meaning they are equal to each other
Knowing the angles are equal to each other you can make the equation
2x + 29 = 9x - 13
then you solve for x in this equation
2x + 29 = 9x - 13
(subtract 2x from both sides)
29 = 7x - 13
(add 13 to both sides)
42 = 7x
(divide by 7 on both sides)
6 = x
x = 6
Answer:
-9
Step-by-step explanation:
The mode is the value that appears most often in a set of numbers, and the number -9 appears the most in this set.
18 feet = 18/3 yard = 6 yard
6 inches = 1/2 feet = 1/6 yard
Volumen = (6yar)(6yard)(1/6yard) = 6 cubic yard
Cost = 6 cubic yard * $42.00 / cubic yard = $ 252.00
Answer: the first option, 252.00
