We have equation:
t=20x+31
x is number of years after 1997.
To calculate number of laptops in 2005:
x=2005-1997
x=8
t=20*8+31
t=160+31
t=191
In year 2005 school had 191 laptops.
Note that f(1) = 6(1)+2 = 8. Next, evaluate g(x) at x=8: g(f(1)) = g(8) = 2(8) + 4/5, or 16 4/5.
Answer:
-12
Step-by-step explanation:
you have to divide 48 to (-4) and it equals to -12
so you multiply -12 to (-4) and it gives you 48
You take the whole number and put it in a fraction over 1 then divide by flipping the second fraction and multiplying
