(Sorry fo the graph) The idea is the following, draw the straigh line, and put the numbers -3, -2 ,-1, 0, 1, etc. In the position -3 you need to start to draw the interval solution, with an open circle.
It is like 
In row Three , the numbers are going by 3 every time and in row 6 the numbers are going by 6 every time.
Answer:
Hello there the Correct answer The only answer choice that produces -2x²+2 is D.
Because (-x²+2x+3)+(-x²-2x-1) = -x²+2x+3-x²-2x-1 = -2x²+2
answer: D
Hope It Helps!
Answer:
139
Step-by-step explanation:
a pentagon has degrees that add up to 540 so considering youre given 401 degrees the remaining angle has to be 139
point slope form is y-y1=m(x-x1)
from (6,1) y1 = 1 and x1 = 6
slope is given as -3
so you should have y=1 =-3(x-6)
