Answer: C. 
=======================================================
Explanation:
The x intercept always occurs when y = 0.
Use the unit circle to determine that
when 
So if
, then we have

which shows us that
is the location of one of the infinitely many x intercepts for this function.
Quick Answer.
<span>To solve the slope of 3x + 2y = 8, the equation must first be put into slope intercept form with y on the left side and the remaining numbers on the right side. It can be transformed to 2y = -3x + 8, which will then be simplified down to y = -3/2x + 8. The slope of the line is </span>-3/2<span>.</span>
<span>y = kx find k
21 = k*3
k = 7
Equation:
y = 7x
Find x when y = 42
42 = 7x
x = 42/7
x = 6
answer: </span><span>x = 6 when y = 42</span>
Answer
Logarithm base 9 of 729 is 3.
Step-by-step explanation:
Answer: 
My step-by-step explanation:
1. First thing we do is: Distribute
(x+8)(x−5)x
(x−5)+8(x−5)
2. Second thing:Distribute
x(x−5)+8(x−5)
x^2−5x+8(x−5)
3.Third thing: Distribute
x^2−5x+8(x−5)
x^2−5x+8x−40
4. Fourth thing: Combine like terms
x^2−5x+8x−40
x^2+3x−40
5.And finnaly we find: The solution
x^2+3x−40
Good Luck!
