Perimeter of a rectangle is 15x+17y if the length is 7/2x+7y then find the width of the rectangle
bogdanovich [222]

The perimeter of a rectangle is given by the formula,


P=2l+2w


We substitute,


P=15x+17y


and


l=\frac{7}{2}x+7y


into the above formula to obtain the expression,




15x+17y=2(\frac{7}{2}x+7y)+2w



15x+17y=7x+14y+2w




We now group the x and y terms on the Left Hand Side of the equation to get.


15x-7x+17y-14y=2w




8x+7y=2w



We now divide through by 2 to get,



4x+\frac{7}{2}y=w



Therefore the width of the rectangle is


4x+\frac{7}{2}y

Identify the equation of a line in slope-intercept form that is perpendicular to y = -1/3 x + 2 and passes through (2, 1).
kari74 [83]
To get your answer, you will need to find the perpendicular slope for -1/3x which is just the opposite therefore it will be 3x. Your slope is 3x as perpendicular so use this slope to do point slope. Y-1=3(x-2). Distribute y-1=3x-6. Add 1 to both sides. (-1+1) (-6+1)=-5. So your equation in slope intercept form is y=3x-5. Going through the two points.

Hope this helps!
