Answer:

D : {x ∈ R : x≠1}

Step-by-step explanation:

The domain is what values of x can we put into the function and it still works

We cannot have the denominator equal zero

x-1 ≠0

Add 1 to each side

x-1+1 ≠0+1

x≠1

The domain is all real values of x except x=1

D : {x ∈ R : x≠1}

Solve the system of equations - 8x - 5y = -13 and - 4x – 5y = 11 by<br> combining the equations.
Citrus2011 [14]

Answer:

(6,-7)

Step-by-step explanation:

subtract them:

-8x - 5y = -13

-4x - 5y = 11

you get

-4x = -24

so x = 6

plug x into the second equation:

-24 - 5y = 11

-5y = 35

y = -7

so your solution is (6,-7).

Find the equation of a circle whose endpoints of the diameter are (15, - 3) and (7,3). The equation of the circle is (Simplify y
Nana76 [90]

Answer:

(x - 11)² + y² = 25

Step-by-step explanation:

First find the center

O = ( (15 +7 / 2), (-3 + 3)/2 )

O = (11, 0)

Then find the radius squared

use the distance formula from the center to either end point of the diameter

r² = (15 - 11)² + (-3 - 0)²

r² = 16 + 9

r² = 25

Formula for circle

(x - h)² + (y - k)² = r²

(h, k) is the center = (11, 0)

The equation is

(x - 11)² + y² = 25
