Answer: 7x^2+21x+14
Step-by-step explanation:
(7x+7)(x+2)
Multiply each term in the first parentheses by each term in the second parentheses (FOIL)
7x×x+7x×2+7x+7×2

7x^2+21x+14 is your end result.
Your answer is
- Slope = -1.000/2.000 = -0.500
- x-intercept = 7/1 = 7.00000
- y-intercept = 7/2 = 3.50000
Step-by-step explanation:
y= (-5/2)x - 22
because 5x+2y=12 turns to y=(-5/2)x + 6 and the line parallel to it has to have the same slope so you have to just get the y intercept by plugging in -10 into the equation (-5/2)(-10)+?=3 and ?= -22.
Answer:yes
Step-by-step explanation: the answer does represent a function because if you were to put points in the line wherever, and connect them by drawing a line vertically, it would not cross two points.
Answer:
He should charge 15.75
Step-by-step explanation:
Markup = original price * markup rate
Markup = 9*75%
= 6.75
The new price is the original price plus the markup
New price = original price + markup
New price = 9+6.75
= 15.75
He should charge 15.75
