The answer is C, because those are the points that cross the x-axis.
Each item kimora bought costs $3.
write an expression and solve it
the expression is 70-14p=28
work:
Answer:
Solution given:
9x-2y=7
making it in a form of y=mx+c
9x-7=2y
y=9/2x -7/2
Comparing above equation with y=mx+c
we get
m=9/2
Since it is passes parallel to (5,-3)
slope will be same
now
Equation of line
y-y1=m(x-x1)
y+3=9/2(x-5)
y=9/2x-5/2-3
<u>y=9/2 x-11/2 is a required equation.</u>
Step-by-step explanation:

<h3>
![\frac{2}{ \sqrt{x} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B%20%5Csqrt%7Bx%7D%20%7D%20)
</h3>
Using the rules of indices
<h3>
![\sqrt{x} = {x}^{ \frac{1}{2} }](https://tex.z-dn.net/?f=%20%5Csqrt%7Bx%7D%20%20%3D%20%20%7Bx%7D%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20)
</h3>
So we have
<h3>
![\frac{2}{ {x}^{ \frac{1}{2} } }](https://tex.z-dn.net/?f=%20%5Cfrac%7B2%7D%7B%20%7Bx%7D%5E%7B%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20%7D%20)
</h3>
And also by the rules of indices
<h3>
![\frac{1}{ {a}^{b} } = {a}^{ - b}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20%7Ba%7D%5E%7Bb%7D%20%7D%20%20%3D%20%20%7Ba%7D%5E%7B%20-%20b%7D%20)
</h3>
Applying the rules to the above expression we have the final answer as
<h2>
![2 {x}^{ - \frac{1}{2} }](https://tex.z-dn.net/?f=2%20%7Bx%7D%5E%7B%20-%20%5Cfrac%7B1%7D%7B2%7D%20%7D%20)
</h2>
<h2>B).</h2>
<h3>
![\frac{3}{ {x}^{2} }](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B%20%7Bx%7D%5E%7B2%7D%20%7D%20)
</h3>
By using the rules of indices
<h3>
![\frac{1}{ {a}^{b} } = {a}^{ - b}](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B%20%7Ba%7D%5E%7Bb%7D%20%7D%20%20%3D%20%20%7Ba%7D%5E%7B%20-%20b%7D%20)
</h3>
Applying the rules to the above expression
We have the final answer as
<h2>
![3 {x}^{ - 2}](https://tex.z-dn.net/?f=3%20%7Bx%7D%5E%7B%20-%202%7D%20)
</h2>
