$35.10
22% = 0.22
45(0.22) = 9.90
She has saved $9.90
45 - 9.9 = 35.1
Answer: 9/17
Reason
The reciprocal is simply flipping the denominator and numerator of a fraction.
1-8/9 as a mixed fraction is 17/9
So the reciprocal would be to flip it,
Giving you 9/17 which is in its simplest form
Answer:
In My Opinion, <u>y < 425 - x</u>
I hope this helps.
Answer:9|4 i think maybe wrong

Answer:
Option D. ![y=-4x^{2} -16x-12](https://tex.z-dn.net/?f=y%3D-4x%5E%7B2%7D%20-16x-12)
Step-by-step explanation:
using a graphing tool
Graph and determine the vertex in each case
we know that
If the equation has a maximum value at x=-2, then the x-coordinate of the vertex must be equal to -2 and the parabola open downward
case A) ![y=-x^{2} -20x-16](https://tex.z-dn.net/?f=y%3D-x%5E%7B2%7D%20-20x-16)
The vertex is the point ![(-10,84)](https://tex.z-dn.net/?f=%28-10%2C84%29)
case B) ![y=-x^{2} -16x-12](https://tex.z-dn.net/?f=y%3D-x%5E%7B2%7D%20-16x-12)
The vertex is the point ![(-8,52)](https://tex.z-dn.net/?f=%28-8%2C52%29)
case C) ![y=-4x^{2} -20x-16](https://tex.z-dn.net/?f=y%3D-4x%5E%7B2%7D%20-20x-16)
The vertex is the point ![(-2.5,9)](https://tex.z-dn.net/?f=%28-2.5%2C9%29)
case D) ![y=-4x^{2} -16x-12](https://tex.z-dn.net/?f=y%3D-4x%5E%7B2%7D%20-16x-12)
The vertex is the point
-------> is the answer
