Answer:
The correct answer is "x = 4" and "x = -12".
Step-by-step explanation:
The given equation is:
⇒ 
On subtracting "18" from both sides, we get
⇒ 
⇒ 
On applying factorization, we get
⇒ 
On taking common, we get
⇒
⇒ 
⇒ 

or,

Answer:
y = -5(x +6) -9
Step-by-step explanation:
The point-slope form of the equation for a line can be written as ...
y = m(x -h) +k
for a line with slope m through point (h, k).
You have m=-5 and (h, k) = (-6, -9). Filling in these values gives ...
y = -5(x -(-6)) -9
Simplifying a bit, you get ...
y = -5(x +6) -9
Answer:
$125,500
Step-by-step explanation:
Make "x" equal the selling price of the house
7% of x is the commission --->
.07 * x = 8785
x= 8785/ .07
x= 125500
Answer:
a) 1/27
b) 16
c) 1/8
Step-by-step explanation:
a) 
One of the properties of the exponents tells us that when we have a negative exponent we can express it in terms of its positive exponent by turning it into the denominator (and changing its sign), so we would have:

And now, solving for x = 9 we have:

b) 
This is already a positive rational exponent so we are just going to substitute the value of y = 8 into the expression

c) 
Using the same property we used in a) we have:

And now, solving for z = 16 we have:
