Answer:
8 in.
Step-by-step explanation:
Perimeter of a rectangle, P = 2(L + W)
Value of P = 46.
Length is 7 inches less than the width. This translates to L = W - 7
Substitute L = W - 7 into the perimeter equation, you get
46 = 2(W - 7 + W)
46 = 2(2W - 7)
46 = 4W - 14
4W = 60
W = 60 / 4 = 15 in
L = W - 7 = 15 - 7 = 8 in

Step-by-step explanation:
Answer:
y = -2(x + 1)
Step-by-step explanation:
x-intercept of -1 means y=0 when x=-1, so you have your (x₁, y₁) value of (-1, 0).
Slope is -2 so m=-2.
Plug into point-slope formula:
y = m(x - x₁) + y₁
y = (-2)(x - (-1)) + (0)
y = -2(x + 1)
