Answer: f(2) = -4
Step-by-step explanation: Here we're given the function f(x) = -3x + 2 and we are asked to find f(2).
In other words, if we put an <em>x</em> into our function, we get a -3x + 2 out so what happens when we put a 2 into the function?
Well if we put a 2 into the function,
that's f(2) and we get -3(2) + 2 out.
Now all we have to do is simplify on the right side.
-3(2) is -6 so we have -6 + 2 which is -4.
So f(2) is -4.
Answer:
D
Step-by-step explanation:
Alright, so we know that they can unload 25 trucks in 5 hours.
If we do 25/5 We find out that they can unload <u>5 trucks per hour</u>
Unfortunately, that is not one of the answers, so we will have to do some investigating to find something that is <u>equivalent</u>!
After evaluating the available answers, you can find that answer D lines up with our first assumption!
Every 1/5th of an hour the Fast-Pack people can unload a truck!
We can calculate this by writing:
1/5*25=<u>5</u>
<u></u>
Please let me know if you have any confusion! :)
-15x - 3y = 3
-15x - 3(5x-1) = 3 [input y]
-15x - 15x - 3 = 3 [distribute 3 over 5x and -1]
-30x - 3 = 3 [combine like terms]
-30x = 6 [add 3 to eliminate the negative]
x =

[divide by -30 to get x alone]
x =

[reduce the fraction]
Hopefully this is helpful enough to get you to your answer

Answer:
60
Step-by-step explanation:
x and 2x are linear pair angles.
Sum of linear pair angles is 180,
x + 2x = 180
3x = 180
x = 180 / 3
x = 60
Therefore,
the value of x is 60.
