Answer:
15
Step-by-step explanation:
We add the exponents so it is 10+5=15
well, looking at the picture of this vertically opening parabola, it has a vertex at 0,0 and it passes through 2,1 hmm ok

Step-by-step explanation:
sorry
Answer:
0.33 liters of water Bao use per liter of flour.
3 liters of flour Bao use per liter of water
Step-by-step explanation:
Given the graph which pass through the coordinates (0,0) and (3,1)
∴ Equation of line passing through these points can be written as
![(y-y')=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}(x-x')](https://tex.z-dn.net/?f=%28y-y%27%29%3D%5Cfrac%7By_%7B2%7D-y_%7B1%7D%7D%7Bx_%7B2%7D-x_%7B1%7D%7D%28x-x%27%29)
⇒ ![(y-0)=\frac{1-0}{3-0} (x-0)](https://tex.z-dn.net/?f=%28y-0%29%3D%5Cfrac%7B1-0%7D%7B3-0%7D%20%28x-0%29)
⇒
⇒ ![3y=x](https://tex.z-dn.net/?f=3y%3Dx)
Now, we have to find liters of water Bao use per liter of flour i.e if x=1 then we find the value of y which is 3y=x=1 ⇒ ![y=\frac{1}{3} = 0.33 l](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B1%7D%7B3%7D%20%3D%200.33%20l)
Now, we have to find liters of flour Bao use per liter of water i.e if y=1 the we have to find the value of x which is x=3 litre
