3x + 1 - 8x +12 =
so 8x - 3x =5x
1 + 12= 13
so answer is 5x+13
Perimeter is 2(2x+5)+2(x-2) which is 4x+10+2x-4 which is in turn 6x+6. 6x+6 is the perimeter. Hope I helped!
Answers:
Domain = {-24, -6, -4, 4, 21, 47}
Range = {24, 55, 45, 77, 3, 93}
Don't forget about the curly braces.
The domain is the set of all allowed x inputs. So we simply list all the x coordinates of the points given. That's all there is to it. The range is the list of all possible y output values, so we just list the y coordinates. Toss out any duplicate y values. Sorting each set is optional because order doesn't matter in a set.
Answer:
That is not a good estimate.
Step-by-step explanation:
42 + 19 = 61
61 + 32 = 93
