Answer:

Length is 3 meters and the Width is 5 meters

Step-by-step explanation:

L*W=15

L=2W-7

(2W-7)W=15

2W^{2} -7W=15\\2W^{2} -7W-15=0

(2W+3)(W-5)=0, don't use (2W+3)=0, because it gives you a negative dimension.

W=5, L=3

there is a line that includes the point (6,-4) and has the slope of -2. What is the equation in slope intercept form
Helga [31]

Answer:

y= -2x+8

Step-by-step explanation:

y-y₁=m(x-x₁)

This is the point slope form equation that can be used to solve this.

Plug in the slope for m and (6,-4) for (x₁,y₁)

y-(-4)=-2(x-6)

Simplify.

y+4= -2x+12

y= -2x+8
