WILL GIVE BRAINLIEST find the value of r (-4,8), (r,12), m=4/3 (show your work pls)

OLEGan [10]

Answer:

r = 13

Step-by-step explanation:

The first step is to find b from y=mx=b using m=4/3 and (-4,8)

$8=\frac{4}{3}(-4)+b$

After solving the equation, b will equal -16/3 making the final equation be

$y=\frac{4}{3} x-\frac{16}{3}$

Using the equation, you can solve for r.

$12=\frac{4}{3} x-\frac{16}{3}$

This will bring the answer being r = 13

which of the following is a result of shiftinga circle with equation (×-2)+(y-3)^2= 25 to the left 2 unit ?

Paha777 [63]

Answer:

x^2+(y-1)^2=25

Step-by-step explanation:

eqn of circle : (x-h)^2+(y-k)^2=r^2

center of circle = (h,k)

hence, the center of the current circle is (2,3)

moving 2 units to the left would make the center (0,1)

the radius would remain the same (5) , hence the new eqn would be

(x-0)^2+(y-1)^2=25

x^2+(y-1)^2=25
