Answer:
- (-16x² +10x -3) +(4x² -29x -2)
- (2x² -11x -9) -(14x² +8x -4)
- 2(x -1) -3(4x² +7x +1)
Step-by-step explanation:
I find it takes less work if I can eliminate obviously wrong answers. Toward that end, we can consider the constant terms only:
- -3 +(-2) = -5 . . . . possible equivalent
- -10 -5 = -15 . . . . NOT equivalent
- 3(-5) -2(5) = -25 . . . . NOT equivalent
- -9 -(-4) = -5 . . . . possible equivalent
- -7 -(-5) = -2 . . . . NOT equivalent
- 2(-1) -3(1) = -5 . . possible equivalent
Now, we can go back and check the other terms in the candidate expressions we have identified.
1. (-16x² +10x -3) +(4x² -29x -2) = (-16+4)x² +(10-29)x -5 = -12x² -19x -5 . . . OK
4. (2x² -11x -9) -(14x² +8x -4) = (2-14)x² +(-11-8)x -5 = -12x² -19x -5 . . . OK
6. 2(x -1) -3(4x² +7x +1) = -12x² +(2 -3·7)x -5 = -12x² -19x -5 . . . OK
All three of the "possible equivalent" expressions we identified on the first pass are fully equivalent to the target expression. These are your answer choices.
Answer:
1:10pm
Step-by-step explanation:
1st, you add all the time needed to make the chili & cook it.
1 hour + 10 minutes + 1 hour + 40 minutes = 2 hours & 50 minutes.
Now you work backwards from 4:00pm.
You go back 2 hours & you would be at 2:00pm
Now you go back another 50 minutes & you would be at 1:10pm
To double check, you can add 2 hours & 50 minutes to 1:10pm & you would get 4:00pm
When x > 2, 2x + 3 > 7 and when x = 2, 2x + 3 = 7. ... problem, assume that Christina's average points per game was greater than or equal to 3. Use . Indirect Proof: ... x is an odd integer must be true. Write an indirect proof of each statement. 9.
Step-by-step explanation:
its wrong cuz
17 / 3 + 1/ 3 = 18/3 = 6
