4(x + 9) + 5x = 9x - 36
=> 4x + 36 + 5x = 9x - 36
=> 9x + 36 = 9x - 36
=> 9x - 9x = -36 - 36
=> 0 = -72
You can see that the equation doesn't hold true.
So there is no solution for this equation.
Answer is C. no real solutions
Answer:
x-intercept: (-7.5 , 0) y-intercept: (0 , 5.5)
Step-by-step explanation:
<span>A common factor is a factor of 2 or more numbers.
the factors of 12 are: 1,2,3,4,6,12
the factors of 21 are: 1,3,7,21
1 and 3 are both common factors of 12 and 21.</span>
Answer:
D - x = 19 x = -17
Step-by-step explanation:
Factor the equation to make the problem easier - you should have this:
(x - 18) (x + 18) = 1
Set each binomial to 1:
x - 18 = 1
x + 18 = 1
This should give you x = 19 and x = -17
The correct answer is that a factor of f(x) is (x+1)
This is due to the zero product property, which states that if two binomials multiply to 0, then one of its factors must equal 0.
(x+1) must equal 0.
(x+1)=0
x=-1
If (x-1)=0, then x would equal 1 instead of -1 which is what the question is asking for.
