two times a number n plus three
Answer:
B. y = 2x + 1
Step-by-step explanation:
Substitute the information into the point-slope form equation.
y - y₁ = m(x - x₁)
y - (-5) = 2(x - (-3)
y + 5 = 2(x + 3)
y + 5 = 2x + 6
y = 2x + 1
Answer:
false

Answer:
For the given circle, the center is at (-7,4) and radius is 7
Step-by-step explanation:
Given equation of the circle is ![(x+7)^2+(y-4)^2=49\hfill (1)](https://tex.z-dn.net/?f=%28x%2B7%29%5E2%2B%28y-4%29%5E2%3D49%5Chfill%20%281%29)
To find the center and radius of given circle with the help of its equation:
Equation of the circle is of the form
(x-h)^2+(y-k)^2=r^2\hfill (2)[/tex] with center at (h,k) and radius is r.
Given ![(x+7)^2+(y-4)^2=49](https://tex.z-dn.net/?f=%28x%2B7%29%5E2%2B%28y-4%29%5E2%3D49)
The above equation can be written as,
![(x-(-7))^2+(y-4)^2=7^2\hfill (3)](https://tex.z-dn.net/?f=%28x-%28-7%29%29%5E2%2B%28y-4%29%5E2%3D7%5E2%5Chfill%20%283%29)
Now comparing the equations (2) and (3) we get
h=-7, k=4 and r=7
Therefore center at (h,k) is (-7,4) and radius is 7
For the given circle, the center is at (-7,4) and radius is 7
You would do 312 ÷ 52 because if he's going at 52 miles per hour then this gives you the amount of hours. 312 ÷ 52 = 6, so your answer is 6 hours. I hope this helps!
