Remember the f(x) is the same thing as y so...
y = -3x + 5
y = -1
To solve this plug -1 in for y in the equation y = -3x + 5 and solve for x
-1 = -3x + 5
-6 = -3x
2 = x
When f(x) is -1 then x is 2
Hope this helped!

Question:
Obtian the equation that can be used to solve for c
Answer:
Sin50 = 3/c
Step-by-step explanation:
A triangle showing the information given has been attached below for clarity :
Using trigonometry :
AC = 3 = opposite side of angle 50°
AB = c = hypotenus
Using the sine relation of a right angled triangle :
Sin θ = opposite / hypotenus
θ = 50°
Sin 50° = 3 / c
Sin50 = 3/c
Number eight would be 30 and number nine would be $6
