Answer:
y is also doubled.
Step-by-step explanation:
Direct proportionality between
and
means that
![y \propto x](https://tex.z-dn.net/?f=y%20%5Cpropto%20x)
or
,
which indicates a linear relationship between
and
because they are related by a constant.
Therefore, if x is doubled, then the new value of
is ![y_{new}](https://tex.z-dn.net/?f=y_%7Bnew%7D)
![y_{new}=c(2x)](https://tex.z-dn.net/?f=y_%7Bnew%7D%3Dc%282x%29)
![y_{new}=2(cx)](https://tex.z-dn.net/?f=y_%7Bnew%7D%3D2%28cx%29)
![y_{new}=2y](https://tex.z-dn.net/?f=y_%7Bnew%7D%3D2y)
The new value of
is 2 times the previous; therefore,
is doubled as
is doubled.
With 6 people preparing bags, they would be able to prepare 6 bags every 2 minutes.
900/6 * 2 = the total minutes
Divide that answer by 60 to get the numbe of hours.
The answer is 5 hours.
Hope that helps.- UF aka Nadia
Answer:
y = (2/5)x + 3
Step-by-step explanation:
Note that the y-intercept is (0, 3) and that the line passes right through the point (5, 5). First we find the slope of this line: m = rise/run.
As we move from (0, 3) to (5, 5), we see that x increases by 5 (the run) and y increases by 2 (the rise). Thus, the slope of this line is m = 2/5.
Now we know that m = 2/5, x = 5, y = 5 and b (the y-intercept) is 3. Then our equation is y = mx + b, or y = (2/5)x + 3
Answer:
B) 450
Step-by-step explanation:
You use the greater amount minus the lesser amount, times 30 minutes.
55-40=15
15 x 30=150

25% off means that the original percent subtract 25%, so the original percent is 100%-25%=75%, and we know the the new price is only 75% of the original price.
To find the sale price of the handbag, take:
$155×75%=$116.25. As a result, the sale price of the handbag is $116.25. Hope it help!
