3 = AIA ( Alternate Interior Angles)
4 = Definition of AIA
Answer:
y = 2(x-3)^2 - 2
Step-by-step explanation:
y = 2x^2 - 12x + 16
y = 2(x^2 - 6x + 8)
y = 2(x^2 - 6x +8 +1 -1) you "complete the square" by bringing the last term (8) up to "half of the middle co-efficient squared". Middle co-efficient is -6, half is -3, squared is 9. To get from 8 to 9 you must add 1 (+1), but if you add 1 you must subtract 1 (-1) so that you don't change the overall value of inside the bracket
y = 2(x^2 - 6x +9) - 2 (bring the -1 outside of the brackets)
y = 2(x-3)^2 - 2
Answer:
2
Step-by-step explanation:
these are alternative interior angles so they are equal to each other (congruent) soooo
9x + 4 = 3x + 16
subtract:
9x = 3x + 12
6x = 12
divide
x = 2
917 - 67 = 850 (subtract the difference)
850 / 2 = 425 (divide the cost of the washer/dryer)
425 + 67 = 492 (add the difference)
The dryer costs $492.
Answer:
The two in the middle are the negatives and the two that are on the sides are positive.
