Answer:

(x+9)^2 + ( y-2) ^2 = 25

Step-by-step explanation:

The equation of a circle can be written as

(x-h)^2 + ( y-k) ^2 = r^2 where ( h,k) is the center and r is the radius

(x--9)^2 + ( y-2) ^2 = 5^2

(x+9)^2 + ( y-2) ^2 = 25

The table represents a linear function.<br> What is the slope of the function?

TEA [102]

Answer:

-4

Step-by-step explanation:

The function is linear; therefore, the slope of the line joining any two points is the same.

We take any two points from the table and compute the slope or rise/ run between them— let is take points (-4, -2) and (-2, -10).

The slope $m$ of the line joining the points is

$m=\dfrac{\Delta y }{\Delta x } =\dfrac{-2-(-10)}{-4-(-2)} \\\\\boxed{m=-4}$

The slope of the function is -4.

Consider the following system of equations:

Kobotan [32]

Answer:

x=-15, y=25. (-15, 25).

Step-by-step explanation:

2x+3y=45

x+y=10

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

x=10-y

2(10-y)+3y=45

20-2y+3y=45

20+y=45

y=45-20

y=25

x+25=10

x=10-25

x=-15
