Answer:

(x − 4)2 + (y + 6)2 = 25

(x − 4)2 + (y − (-6))2 = 52

When I compare my equation with the standard form, (x − h)2 + (y − k)2 = r2, I get h = 4, k = -6, and r = 5. The center is at (4, -6), and the length of the radius is 5.

Answer:

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

Step-by-step explanation:

Here, we want to write the standard equation of the circle

We have this as;

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

The above equation is the standard equation for the circle

Choose the best reason for using the median as the measure of central tendency.
Alchen [17]

Answer:

The median is usually preferred in these situations because the value of the mean can be distorted by the outliers. However, it will depend on how influential the outliers are. If they do not significantly distort the mean, using the mean as the measure of central tendency will usually be preferred.

What is 45% of 90 ?
Liula [17]

Answer:

40.5

Step-by-step explanation:

This answer makes sense because we know that 50% of 90 is 45.

Since 45% of 90 is 40.5, we can self-check our answer.

Hope I helped!

Solve the system of equations and choose the correct ordered pair. 3y=4x+7 and 5y=4x+25​
Luba_88 [7]

Answer:

(5,9)

Step-by-step explanation:

3y=4x+7

5y=4x+25​

Subtract the two equations to eliminate x

5y=4x+25

-( ​3y=4x+7)

------------------

2y = 0x +18

Divide by 2

2y/2 = 18/2

y =9

Now find x

3y = 4x+7

3*9 = 4x+7

27 = 4x+7

Subtract 7

20 = 4x

Divide 4

20/4 = 4x/4

5 =x

(5,9)
