Answer:
the answer is 1/y^3
Step-by-step explanation:
when ever there is an negative exponent you flip it and put the base and exponent in a fraction under 1 hope this helps
-4x + 10y = -4
10y = 4x - 4
y = 2/5 x - 2/5 so slope = 2/5
-2 - 2x = 5y
5y = -2x - 2
y = -2/5 x - 2/5 so slope = -2/5
the slope is opposite so the lines are intersecting
answer is A.
I believe the correct answer is C - 1,152
Let the width = w.
Then the length is 3w - 5.
The area = LW = 28
w(3w - 5) = 28
3w^2 - 5w = 28
3w^2 - 5w - 28 = 0
(3w + 7)(w - 4) = 0
3w + 7 = 0 or w - 4 = 0
w = -7/3 or w = 4
The width of a rectangle cannot be a negative number, so we discard w = -7/3.
The width is 4 ft.
The length is 3w - 5 = 3(4) - 5 = 12 - 5 = 7
The length is 7 ft
Answer: The dimensions are length 7 ft and width 4 ft.
