Answer:
![y=5x+3](https://tex.z-dn.net/?f=y%3D5x%2B3)
Step-by-step explanation:
Slope-intercept form:
where
is the slope and
is the y-intercept (the value of y when the line crosses the y-axis)
<u>1) Plug the given slope 5 into the equation</u>
![y=mx+b\\y=5x+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb%5C%5Cy%3D5x%2Bb)
<u>2) Find the y-intercept </u>
<u> by plugging in the point (-1,-2)</u>
![y=5x+b\\-2=5(-1)+b\\-2=-5+b](https://tex.z-dn.net/?f=y%3D5x%2Bb%5C%5C-2%3D5%28-1%29%2Bb%5C%5C-2%3D-5%2Bb)
Add 5 to both sides
![-2+5=-5+b+5\\3=b](https://tex.z-dn.net/?f=-2%2B5%3D-5%2Bb%2B5%5C%5C3%3Db)
<u>3) Plug the y-intercept back into the equation</u>
![y=5x+3](https://tex.z-dn.net/?f=y%3D5x%2B3)
I hope this helps!
D is the answer, Since D is division and polynomials are not closed under division.
Answer:
![A=49\pi\ cm^2](https://tex.z-dn.net/?f=A%3D49%5Cpi%5C%20cm%5E2)
Step-by-step explanation:
we know that
The area of a circle is equal to
![A=\pi r^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E%7B2%7D)
The radius of the new circle is equal to
---> the radius is half the diameter
substitute
![A=\pi (7)^{2}](https://tex.z-dn.net/?f=A%3D%5Cpi%20%287%29%5E%7B2%7D)
![A=49\pi\ cm^2](https://tex.z-dn.net/?f=A%3D49%5Cpi%5C%20cm%5E2)
