Opposite means add a negative sign in front of it.

The opposite of 6 is -6,

7 --> -7,

-10 --> 10.

Reciprocal means flip it.

Reciprocal of 6 is 1/6

of 7 is 1/7

of -10 is -1/10

Opposite reciprocal means add a negative sign AND flip it.

6 --> -1/6

7 ---> -1/7

-10 --> 1/10

In geometry, perpendicular lines on a graph have opposite reciprocal slopes.

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
