The product of the two is 0, so one of them have to equal 0 as any number multiplied by 0 is 0.
First solution: x - 4 = 0
If x - 4 = 0, then x = 4. So the first solution for <em>x </em>is 4.
Second Solution: -5x + 1 = 0
Solving...
-5x + 1 = 0
-5x = -1
x = -1/-5
x = 1/5 or 0.2
So x = 0.2 and 4
Answer:
34x
Step-by-step explanation:
22/x=9/100
22*100=9x
2200=9x
2200/9=x

Answer:
x = - 8, x = 2
Step-by-step explanation:
Given
f(x) = x² + 6x - 16
To find the x- intercepts equate f(x) to zero, that is
x² + 6x - 16 = 0 ← in standard form
(x + 8)(x - 2) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 8 = 0 ⇒ x = - 8
x - 2 = 0 ⇒ x = 2
