3 launchers + shipping = $50
shipping = $5
so to find the price of just the launchers we do $50-$5=$45
so 3 ballons = $45
divide be 3 to find the price of one launcher $50 / 3 = $15
Answer:
A)(7,-9)
Step-by-step explanation:
we know x=7
so put it in the equation
y= -2(7)+5
y=-9
we always put the x coordinate first and then the y coordinate so the answer is (7,-9)
Answer:
Conclusion
Step-by-step explanation:
So you proved something Then you conclude something else)))
The total elevation that the scuba driver does is from
![-29 \frac{7}{10}](https://tex.z-dn.net/?f=-29%20%5Cfrac%7B7%7D%7B10%7D%20)
to
![-28 \frac{9}{10}](https://tex.z-dn.net/?f=-28%20%5Cfrac%7B9%7D%7B10%7D%20)
The ascending distance =
![-28 \frac{9}{10}--29 \frac{7}{10}](https://tex.z-dn.net/?f=-28%20%5Cfrac%7B9%7D%7B10%7D--29%20%5Cfrac%7B7%7D%7B10%7D%20)
The ascending distance =
![\frac{4}{5} feet](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20feet)
The time (t) taken during the ascend = 19.125 - 12.75 = 6.375 minutes
The average change in speed is given by the ascending distance divided by time taken during the ascend =
![\frac{4}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B4%7D%7B5%7D%20)
÷ 6.375 = 0.125 feet/minute
