Write an equation for the line that passes through (2,-5) and is parallel to 3x+4y=8

mote1985 [20]

3x+4y=8
4y = -3x + 8; slope = -3
parallel lines, slope is the same so slope = -3
passes through (2,-5)
y = mx + b
b = y - mx
b = -5 - (-3)(2)
b = -5 + 6
b = 1

equation
y = -3x +1

A rectangle has a perimeter of 44 inches and an area of 72 square inches. What are the lengths of the sides of the rectangle?

kondor19780726 [428]

A rectangle has a perimeter of 44 inches and an area of 72 square inches.
Perimeter = 44 inches, area = 72 square inches.
Let the length and breadth be l and b respectively.
We know, perimeter of a rectangle = 2(l + b)
Therefore,
2(l + b) = 44

or, l + b = 22

or, b = 22 - l ...(i)

We know, area of a rectangle = lb
Therefore,
lb = 72
Putting (i) in b, we get
l(22 - l) = 72

or, 22l - l^2 -72 = 0

or, l^2 - 22l + 72 = 0

or, l^2 - 4l - 18l + 72 = 0

or, l(l - 4) - 18(l - 4) = 0

or, (l - 4)(l - 18) = 0

or, l = 4 or l = 18

Therefore, if the length is 4 inches, then the breadth is (22-4) inches, i.e., 18 inches.
And if the length is 18 inches, then the breadth is (22-18) inches, i.e., 4 inches.

Answer:

B) 4 inches and 18 inches.

Hope you could get an idea from here.
