To find the correct polynomial, we can use the answers to help us out. The middle variable must be the sum of +2 and another number; the last number in the equation must be the product of +2 and the other number.
Knowing this information, we can use the process of elimination to find the exact polynomial that contains the factor (3x + 2).
A) This can't be it because to get -x as the middle variable, you would need to add -3 and +2. However, -3 x +2 doesn't equal -4.
B) This equation isn't the right one because to get +8 you need to add +6 + 2. However, the product of these two isn't -8.
C) Can't be correct because +2 and -7 = -5, but 2 x -7 = -14...not -9.
D) Is the correct answer because you can add 2 and -1 to get +1. (There is an understood +1 in front of the x in the equation.) The product of 2 and -1 equals -2, which happens to be the last number inside this equation. Therefore, this (D) is the correct answer choice.

Answer:
y = 3x + 2
There slope is 3 and intercept is 2.
<u>First find what are the 2 pair that given by slope =3</u>
First consider A. (3, 11) and B. (3, 9)
Tan α = \fraction(11-9)(3-3)
It is undefine.
Next consider A. (3, 11) and BC (5,15)
Tan α = \fraction(15-11)(5-3)
=2
Next consider A. (3, 11) and D. (2,4)
Tan α = \fraction(11-4)(3-2)
=7
Next consider B (3, 9) and C. (5,15)
Tan α = \fraction(15-9)(5-3)
=3
So this is ordered pair is generated from slope =3
Step-by-step explanation:
Answer:
(x-y)(x-y-3)
Step-by-step explanation:
(x-y)² - 3(x-y)
take (x-y) common,
(x-y)(x-y-3)
Money earned by restaurant on Friday=$1073
Money earned by restaurant on Saturday=$1108
Let Money earned by restaurant on Sunday=$x
Average=$1000
Number of observation=3
⇒ 3× 1000=1073+1108+x
⇒3000= 2 181+x
⇒3000-2181=x
⇒x=819
The restaurant needs to earn on Sunday to average $1000 per day over the three-day period=$819
