Answer:
x=1
Step-by-step explanation:
if it is truly 9^(x-1)=27^(x-1), then you dont really need to use the quadratic fromula.
Find the equation of the line.

Answer:
y = 2/3x - 7
Explanation:
First we must turn 3x + 2y = 6 to slope intercept form. In order to do this first subtract 3x on both sides of the equal sign, so we can get 2y by its self. Now we're left with 2y = -3x + 6 .
Next divide 2 from both sides to get y by its self. Now you got y = -3/2x + 3 (since 6 can be divided by 2 it's a 3 now) <u>Look above to see y= -3/2x +3 graphed</u>. ⤴⤴⤴
To find out the other equation we first need to know what its y-intercept is, and luckily for us we've already been given -3.

This is a bit lengthy, but I hope you get it :)

Answer:
x = - 9 , 6
Step-by-step explanation:
The given function is
⇒
Therefore, the value of h(x) will be undefined for the denominator equal to zero.
So, (x + 9)(x - 6) = 0
⇒ x = - 9 and x = 6
Therefore, the values of x which are not in domain of function h(x) are x = - 9 , 6. (Answer)
Well, sine is 
,
but from the angle C, the opposite side, the one facing it off, is the side
AB, and we dunno what the side AB is
however, we know the hypotenuse is 8, and the adjacent side is 7,
and is right-triangle, thus, let us use the pythagorean theorem,
now, that we know what the opposite side is, that is AB, then
we can find the sine of angle C
