PIT_PIT [208]

Answer:

y - 3 = 5( x- 2)

Here the slope is 5 and the point is (2,3).

Substitute and you'll have:

y - 3 = 5( x- 2)

f a rectangle has a perimeter of 70, a length of x and a width of x - 9, find the value of the length of the rectangle.
trasher [3.6K]

( x + (x  -  9))  \times 2 = 70 \\( 2x - 9) \times2= 70 \\ 4x - 18 = 70 \\ 4x = 70 + 18 = 88
x =  \frac{88}{4}  = 22
the length is 22


and the width is
22-9=17
