Answer:
Step-by-step explanation:
g(t)=|17-t|
A)g(11)=|17-11|
= |6|
= 6
B)g(12)=|17-12|
=|5|
=5
To answer the question above, let x the number of hours for the two jobs to cost equal. Harry's charge can be expressed as 70x + 130 and that of Lou is 80x + 40. Equating both,
70x + 130 = 80x + 40 ; x = 9
Thus, the job should take 9 hours for both charges to be equal.
You have to distribute the 4 to the numbers in the parenthesese. So 4 times 3x which is 12x and 4 times 5 which is 20 so now you get 12x plus 20 equals 8. Now you have to subtract 20 from 8 which is -12 so now you have 12x=-12 now divide the 12 from x and 12 from -12 and so now you have x=-1
Answer:
-16
Step-by-step explanation:
fog(x)=f(gx)
= -5×4+4
= -20+4
= -16
Answer:
g(-3) = -10
Step-by-step explanation:
All you have to do is plug -3 in for x!
g(-3) = 2(-3) - 4
g(-3) = -6 - 4
g(-3) = -10
