Answer:

Step-by-step explanation:
![(x+1-i)(x+1+i)\\\\=(x+1)^2 -i^2~~~~~~~~~~~~~;[a^2 -b^2 = (a+b)(a-b)]\\\\=x^2 +2x +1 -(-1)\\\\=x^2 +2x +1+1\\\\=x^2 +2x +2](https://tex.z-dn.net/?f=%28x%2B1-i%29%28x%2B1%2Bi%29%5C%5C%5C%5C%3D%28x%2B1%29%5E2%20-i%5E2~~~~~~~~~~~~~%3B%5Ba%5E2%20-b%5E2%20%3D%20%28a%2Bb%29%28a-b%29%5D%5C%5C%5C%5C%3Dx%5E2%20%2B2x%20%2B1%20-%28-1%29%5C%5C%5C%5C%3Dx%5E2%20%2B2x%20%2B1%2B1%5C%5C%5C%5C%3Dx%5E2%20%2B2x%20%2B2)
Answer:
Slope: -2
y-intercept: -3 or (0, -3)
Step-by-step explanation:
y = mx + b
m = slope
b = y-intercept
6x+3y= -9
3y = -6x - 9
y = -2x - 3
Answer:
Line 1 is 1/3
Line 2 is 1/3 as well
Choice 1
Step-by-step explanation:
<u>Rise over run</u>
<em><u>Line 1:</u></em>


<u>Simplify:</u>
1/3
<em><u>Line 2:</u></em>


1/3
1 is Paralell to 2 because they have the same slope
I hope this helps! :D
Pls give thx and brainliest if i’m right!
Answer:
At most Mr.Gengel can cut at most 13 pieces with half a foot left.
Answer:
y = 3x
Step-by-step explanation:
x is number of cartons of eggs
y is cost
cost increases by 3 for every carton of eggs, so slope is 3
x and y intercepts are zero because there is no cost when there are no eggs
equation: y = 3x
