The value of x when h(x) = -1 is 3.5
Step-by-step explanation:
In the function f(x) = y
- x is the input
- y is the output
∵ h(x) = -6x + 20
∵ h(x) = -1
- Substitute h(x) by -1 in the function above to find the value of x
∴ -1 = -6x + 20
- Subtract 20 from both sides
∴ -1 - 20 = -6x + 20 - 20
∴ -21 = -6x
- Divide both sides by (-6)
∴ [tex]\frac{-21}{-6}=\frac{-6x}{-6}[/tex]
∴ 3.5 = x
The value of x when h(x) = -1 is 3.5
