Let’s double the number so 1/8= 2/16
She can eat 6 slices in 1 hour and it takes her 160 minutes or 2 hours and 40 minutes to finish the entire pizza.
Hope this helps! :3
Answer: 33 1/3%
Step-by-step explanation:
Percentage increase of the shirt will be calculated as:
= Price Increase / Old price × 100%
Price Increase = $20 - $15 = $5
Old price = $15
Percent increase = Price Increase / Old price × 100%
= 5/15 × 100
= 1/3 × 100
= 33 1/3%
Answer:
16 yards
Step-by-step explanation:
Using the formula
A=hb/2
Solving forb
b=2A/hb=2·72
9=16yd
Answer:
![\textsf{A)}\quad y=-\sqrt{x}+2](https://tex.z-dn.net/?f=%5Ctextsf%7BA%29%7D%5Cquad%20y%3D-%5Csqrt%7Bx%7D%2B2)
Step-by-step explanation:
Parent function:
![y = \sqrt{x}](https://tex.z-dn.net/?f=y%20%3D%20%5Csqrt%7Bx%7D)
The properties of the parent function are:
- Starts at the origin, so y-intercept is at (0, 0)
- Domain: x ≥ 0
- Range: y ≥ 0
- As x increases, y increases
From inspection of the graph, as the x-values increase, the y-values decrease. Therefore there has been a <u>reflection in the x-axis</u>.
The y-intercept is now at (0, 2), therefore the function has been <u>translated 2 units up</u>.
<u>Translations</u>
For a > 0
![y=-f(x) \implies f(x) \: \textsf{reflected in the} \: x \textsf{-axis}](https://tex.z-dn.net/?f=y%3D-f%28x%29%20%5Cimplies%20f%28x%29%20%5C%3A%20%5Ctextsf%7Breflected%20in%20the%7D%20%5C%3A%20x%20%5Ctextsf%7B-axis%7D)
![f(x)+a \implies f(x) \: \textsf{translated}\:a\:\textsf{units up}](https://tex.z-dn.net/?f=f%28x%29%2Ba%20%5Cimplies%20f%28x%29%20%5C%3A%20%5Ctextsf%7Btranslated%7D%5C%3Aa%5C%3A%5Ctextsf%7Bunits%20up%7D)
Therefore:
Reflected in the x-axis: ![-f(x)=-\sqrt{x}](https://tex.z-dn.net/?f=-f%28x%29%3D-%5Csqrt%7Bx%7D)
Then translated 2 units up: ![-f(x)+2=-\sqrt{x}+2](https://tex.z-dn.net/?f=-f%28x%29%2B2%3D-%5Csqrt%7Bx%7D%2B2)
So the equation that represents the transformed function is:
![y=-\sqrt{x}+2](https://tex.z-dn.net/?f=y%3D-%5Csqrt%7Bx%7D%2B2)
Answer:
x=0 x=2
Step-by-step explanation:
4x=y
2x^2-y=0
If y=4x you can use substitution
2x^2-4x=0
2x(x-2)=0
2x=0 x-2=0
x=0 x=2
