Answer:
(r+s) (x) = 4x+3
(r*s) (x) = 3x^2 +x-4
(r-s) (-1) = -3
Step-by-step explanation:
r(x) = x-1
s(x) = 3x+4
(r+s) (x) = x-1 + 3x+4
Combine like terms
= 4x+3
(r*s) (x) = ( x-1) ( 3x+4)
FOIL
= 3x^2 +4x-3x-4
= 3x^2 +x-4
(r-s) (x) = x-1 - (3x+4)
Distribute the minus sign
=x-1-3x-4
=-2x-5
Let x = -1
(r-s) (-1) = -2(-1) -5
2-5
-3
Answer:
it's equal since they are opposites

Answer:
The ratio of food costs to take home is <u>1 : 6</u>.
Step-by-step explanation:
Given:
Carol's monthly take home pay is 1500$. She spends $250 a month on food.
Now, to find the ratio of food costs to take home pay.
Take home pay = $1500.
Cost of food = $250.
So, getting the ratio:
Cost of food : take home pay
$250 : $1500
Therefore, the ratio of food costs to take home is 1 : 6.
The biker wants to sell a bike for $600 post mark up. You are trying to figure out the retail price as the store owner so that after the 55% mark up, the sale price is $600.
