There are 27 bricks in the 12th row. Hope this helps ! :)
I believe it would be y=4x^2+1 , it's in a U shape
:)
Answer:
Step-by-step explanation:
<u>Let the times be:</u>
- Bed frame - f
- Bookcase - b
- Chair - c
<u>We have following equations:</u>
- 3f + b + 4c = 56
- 4f + 6c = 66
- 2f + 7b + 3c = 89
<u>Simplify the second equation and subtract from the third one:</u>
<u>Replacing b in the first and third equations:</u>
<u>Four times the bottom equation and subtract the triple the one above:</u>
- 8f - 9f = 4(33) - 3(48)
- f = 12
It takes 12 hours to build one bed frame
Answer:
y = (-4/3)x + 6
Step-by-step explanation:
The Y-intercept of the graph is 6. You can find the slope by following rise over run, or the change in y divided by the change in x. From (0,6) to (3,2), there is a negative 4 change in y and positive 3 change in x.
