Answer:

It should be a graph of two branches, one on the top right, and bottom left, and the center of them should be at (-2, 1).

Step-by-step explanation:

f(x)=(x^2-16)/(x^2-2x-8)

= (x+4)(x-4)/(x-4)(x+2)

=(x+4)/(x+2)

=((x+2)+2)/(x+2)

=1+2/(x+2)

So the center is at (-2, 1)

The ratio of the measures of the angles of a triangle is 3:4:8 what are the measures of the angles?

evablogger [386]

Answer:

36 and 48 and 96

Step-by-step explanation:

add 3+4+8=15

all of the angles in a triangle have to add up to 180

so 180÷15=12

now for this ratio, each part will equal 12

so we have to multiply each of the parts by 12

3×12=36

4×12=48

8×12=96

those are the measures of the angles

you can add them up again and see that they equal 180

you can try dividing and you will see that they also equal the ratio

Solve the equation by Completing the Square<br> x2 – 10x + 13 = 0

user100 [1]

Answer:

$x=5+\sqrt{12}$

$x=5-\sqrt{12}$

Step-by-step explanation:

$x^2-10x+13=0$

$x^2-10x=-13$

$x^2-10x+(\frac{10}{2})^2 =-13+(\frac{10}{2})^2$

$x^2-10x+(5)^2=-13+(5)^2$

$x^2-10x+25=-13+25\\x^2-10x+25=12$

Factor.

$(x-5)^2=12$

Extract the square root.

$x-5=\frac{+}{} \sqrt{12}$

Add 5

$x=5+\sqrt{12}$

$x=5-\sqrt{12}$

WHICH INEQUILITY IS EQUIVALENT TO X-4<9

frez [133]

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

Answer: $\textsf{x} < \textsf{13}$

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

Given: $\textsf{x - 4} < \textsf{9}$

Find: $\textsf{The simplified inequality}$

Solution: In order to simplify the inequality we can simply add 4 to both sides which would isolate x.

<u>Add 4 to both sides</u>

$\textsf{x - 4 + 4} < \textsf{9 + 4}$

$\textsf{x} < \textsf{9 + 4}$

$\textsf{x} < \textsf{13}$

Therefore, an inequality that would be equivalent to the one that was provided in the problem statement is x < 13.
