For the function, f(x) = -3x + 5.
If f(x) = -1, what is the value of x?
1 answer:
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!

Answer:
x=1.75 hour
Step-by-step explanation:
200km=2.5
140km=x
2.5 * 140=200x
350=200x
x=350/200
x=1.75
the time it will take is x=1.75 hour
5=1/5x-3
+3 +3
8=1/5x
8•5 1/5x•5
40=x
That would be 1 - 11/12 - 1/18 = 36/36 - 33/36 - 2/36 = 1/36 answer
