P= 2(x+1) + 3(x-8)
= 2x+2+3x-24
= 5x-22
<h2><u>Question</u>: </h2>
- Find the slope of the line passing through the points ( 4, 5 ) and ( 4, –7 ).
- Find the slope of the line passing through the points ( –5, 5 ) and ( 4, 5 ).
<h2><u>Answer</u>:</h2>
- .•. The slope is undefined where the rise is -2 and has no run.
- .•. The slope is 0 where it has no rise and the run is 9.
When you use the Distributive Property you're really just multiplying the number on the outside by all of the numbers on the inside of the parentheses.
(8 - 3p) (-2) Multiply -2 by 8 and -3p
-2(8) + (-2)(-3p) Multiply
-16 + 6p
Answer/Step-by-step explanation:
Call Monday's price, P
Tuesday's price must just be .80P [ 20% reduction]
Call Wednesday's price reduction ( 1 - R)
So...we have that
Tuesday's price * Wednesday's reduction = (1/2)P
(.80)P *( 1 - R) = (1/2)P divide through by P and note that 1/2 = .50
.80 (1 - R) = .50 divide both sides by .80
1 - R = .50/.80
1 - R = 5/8
1 - 5/8 = R
3/8 = R = .375 = 37.5% = the reduction from Tues. to Wed.
Proof of this...let Monday's price = 100
Tuesdays price = .80 * 100 = 80
Wed price = 80 (1 - R) = 80 (1 - .375) = 50 = half of Mon. price
