Write an equation that is parallel to y=-5/2x-5

NeX [460]

A parallel equation (when graphed) will have the same slope, but a different y-intercept.

As long as you keep y = - $\frac{5}{2}$ x + b, you can input anything for b to solve this question.

Given:

y = - $\frac{5}{2}$ x - 5

Equation of a parallel line:

y = - $\frac{5}{2}$ x + 6, y = - $\frac{5}{2}$ x + 1,356, y = - $\frac{5}{2}$ x - 8, etc

Example answer you can use:

y = - $\frac{5}{2}$ x - 8

A rug is to be centered in a room so that the border around it is of a consistent width on all four sides. If the room is 10 ft

aleksley [76]

Answer:

The width of the border can be 9 feet or 3.5 feet.

Step-by-step explanation:

Let the width be x

Length of room = 10 feet

Breadth of room = 15 feet

Length of rug = 10-2x

Breadth of rug = 15-2x

Area of rug = $(10-2x)(15-2x)$

We are given that the area of the rug is 24 square feet.

So, $(10-2x)(15-2x)=24$ ---A

$150-20x-30x+4x^2=24$

$150-24-50x+4x^2=0$

$126-50x+4x^2=0$

$2(x-9)(2x-7)=0$

$x=9,\frac{7}{2}$

$x=9,3.5$

Substitute x =9 in A

$(10-2(9))(15-2(9))=24$

$24=24$

LHS = RHS

Substitute x = 3.5

$(10-2(3.5))(15-2(3.5))=24$

$24=24$

LHS = RHS

So, The width of the border can be 9 feet or 3.5 feet.
