Step-by-step explanation:
i did the quiz
If f(1) =5-2(1)
F(2)=5-2(2)
Difference means subtract, so we use subtraction:
*first we need to make the fractions have the same denominator
1/4 = 3/12
2/3 = 8/12
126(3/12) - 78(8/12)
*since the fraction in the first term is smaller than the second, make it improper
125(15/12) - 78(8/12)
now simply subtract:
125 - 78
= 47
15 - 8
= 7
* this is now (7/12)
now put them back together:
47(7/12)
That's the final answer!
8/10 of a dollar is the correct answer
16r^2+ 2r -4r
16r^2 - 2r
2r ( 8r -1)
