2x+8x=30. x= #of pens
10x=30. combine like terms
x=3. divide by 10 to isolate (get by itself) x
2(3)=6. the # of white pens are represented by 2x
6 white pens
hope this helped!
Answer:
-4f
Step-by-step explanation:
Hi! Let's work on simplifying this.
f(4) = 4f
f(0) = 0, because anything x 0 is 0
f(-8) = -8f
Our equation is 4f + -8f
We can get rid of the plus negative...
4f - 8f
So we get:
-4f
This should help you out!
Some people call 'n' "zero" for the first term, others call 'n' "1".
-- If n=0 for the first term, then T(0) = 0² + 3 = 3 .
-- If n=1 for the first term, then T(1) = 1² + 3 = 4 .
