Answer:
(y+15) = 4/5(x+5)
Step-by-step explanation:
slope = (-7 - 9)/(-12 - 8) = -16/-20 = 4/5
(y+15) = 4/5(x+5)
17. You are supposed to use the perimeter formula for a rectangle. Your text has apparently written that formula as
.. P = 2w +2l
You are given values for P and l. Put them in the formula.
.. 6 = 2w +2*1
Solve in the usual way. First, subtract 2.
.. 4 = 2w
Then, divide by 2
.. 2 = w
You have found w, and it is 2.

Personally, I like to write the perimeter formula for a rectangle as
.. P = 2(w +l)
Usng this version, we can fill in values and get
.. 6 = 2(w +1)
Dividing by 2 gives
.. 3 = w +1
Subtracting 1, we get
.. 2 = w
Answer:
10
Step-by-step explanation:
9 1/6 × 1 1/11
Change each number to an improper fraction
9 1/6 = (6*9 +1)/6 = 55/6
1 1/11 = (11*1 +1) /11 = 12/11
55/6 * 12/11
Rearranging
12/6 *55/11
2/1 *5/1

( 3/4 ) ÷ 4 = ( 3/4) × (1/4) = 3/16 ;
