Answer:

The center is (-4,5) and the radius is 11.

Step-by-step explanation:

The center-radius form for a circle is:

(x-h)^2+(y-k)^2=r^2

where (h,k) is the center and r is the radius.

Compare:

(x-h)^2+(y-k)^2=r^2

(x+4)^2+(y-5)^2=121

-h=4 implies h=-4.

-k=-5 implies k=5

r^2=121 implies r=\sqrt{121}=11.

The center is (-4,5) and the radius is 11.

Answer:

(a) center: (−4, 5); radius: 11

Step-by-step explanation:

(x+4)² + (y−5)² = 121

(x-h)² + (y-k)² = r²

r² = 121

r =11

Find an equation for the line perpendicular to y= -4/3x+5 with​ y-intercept (0,-12). Write the answer in​ slope-intercept form
Arisa [49]

Answer:

y=3/4x−12.

Step-by-step explanation:

Slope of the perpendicular line is negative inverse: m=34.

The equation of the perpendicular line is y=3x4+a.

To find a, we use the fact that the line should pass through the given point: −12=(34)⋅(0)+a.

a=−12.

Therefore, the equation of the line is y=3x4−12.

If you were to use the substitution method to solve the following system, choose the new equation after the expression equivalen
Alisiya [41]
The answer is <span>2(–4y + 13) – 3y = –29

Step 1: Express </span><span>x from the second equation
Step 2: Substitute x into the first equation:

The system of equations is:
</span><span>2x – 3y = –29 
x + 4y = 13

Step 1: 
</span>The second equation is:    x + 4y = 13
Rearrange it to get x:         x = - 4y + 13

Step 2:
The first equation is:          2x – 3y = –29 
The second equation is:    x = - 4y + 13
Substitute x from the second equation into the first one:
2(-4y + 13) - 3y = -29

Therefore, the second choice is correct.
