Slope = (y2 - y1)/(x2 - x1) = (10 - 4)/(-6 - 3) = 6/-9 = -2/3
Answer:
$ 63,250
Step-by-step explanation:
55,000 x 0.15 = 8,250
55,000 + 8,250 = 63,250
Answer:
15 m and 24 m
Step-by-step explanation:
Let x represent the length of the longer side. Then 5/8x is the shorter side and the difference is x -5/8x = 3/8x.
You say the difference is 9 m, so ...
... 3/8x = 9 m
... x = (8/3)(9 m) = 24 m . . . . longer side
and the shorter side is (5/8)(24 m) = 15 m. . . . . shorter side
Simplifying
-2x + -4y = 9
Solving
-2x + -4y = 9
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '4y' to each side of the equation.
-2x + -4y + 4y = 9 + 4y
Combine like terms: -4y + 4y = 0
-2x + 0 = 9 + 4y
-2x = 9 + 4y
Divide each side by '-2'.
x = -4.5 + -2y
Simplifying x = -4.5 + -2y<span>13/18
