PLEASE HELP DUE IN 30 MINUTES!!!

liubo4ka [24]

Answer:

I'm pretty sure the answer to the third question is C

Step-by-step explanation:

We are solving for h(g(x)).

We already know that g(x) is equal to x^2+4.

So know, we can simplify our expression, h(g(x)), to h(x^2+4).

We also know that h(x)=1/x

we simply substitute x for x^2+4, giving us an answer of 1/(x^2+4)

Are the triangles congrouent? if so by what postulate

Roman55 [17]

Answer:

D Not enough information

Step-by-step explanation:

They give us one pair of congruent sides and we know there is a pair of congruent angles because of vertical angles however we can't say for sure that the sides are equal because there is no theorem to prove it and we can't guess by eye in Geometry

Solve 6/×-3 =x/3

Eduardwww [97]

Answer:

X = -3. non-extraneous

Step-by-step explanation:

The given equation is $\frac{6}{x-3} =\frac{x}{3}$

We cross multiply to get:

$6*3=x(x-3)$

Expand and multiply.

$18=x^2-3x$

$x^2-3x-18=0$

We factor to obtain:

$(x-6)(x+3)=0$

$x=-3,x=6$

Checking for extraneous solutions

Substitute x=-3 $\frac{6}{-3-3} =\frac{-3}{3}$

$\frac{6}{-6} =\frac{-3}{3}$

$-1=-1$

$1=1$ .....Non-extraneous

Checking for x=6

$\frac{6}{6-3} =\frac{6}{3}$

$\frac{6}{3} =\frac{6}{3}$

$2=2$ ....Non-extraneous
