What are the excluded values of x for
ss7ja [257]

Answer:

x = - 2, x = 9

Step-by-step explanation:

Given

f(x) = \frac{x^2-9x}{x^2-7x-18}

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the values that x cannot be.

x² - 7x - 18 = 0

(x - 9)(x + 2) = 0

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 9 = 0 ⇒ x = 9

The excluded values are x = - 2, x = 9

4x+8y=17<br> Solve for y
olasank [31]

Answer:

4x + 8y = 17  

Solve for y.

You want to get y on one side of the equal sign by itself so... you subtract 4x from both sides to get:

8y = -4x + 17

Then you divide both sides by 8 to get:

y= -4x/8 +17/8

Then simplify the fractions to get:

y = -2x/4 + 17/8
