<span>ƒ(x) = 1/2x + 4
inverse
x = 1/2 y + 4
2x = y + 8
y = 2x - 8
so inverse f-1(x) = 2x - 8
</span>ƒ -1(4) = 2(4) - 8 = 0
answer
ƒ -1(x) = 2x - 8
ƒ -1(4) = 0
Answer:
y = 4.8(x) + 0
Step-by-step explanation:
In this question, Javier managed to print 240 brochures in 50minutes from 8:00 to 8:50. If we divide these values we see that he printed 4.8 brochures per minute. The same result is given for the 10 minutes from 8:50 to 9:00 where he printed 48 brochures. Therefore, we can get the following linear formula from these values.
y = 4.8(x) + 0
In this case, b would equal 0 because Javier is starting from 0 brochures made when he gets to work at 8:00 a.m

Answer:
$2.25
Step-by-step explanation:
Let c represent the cost of a cup of coffee. Then the total amount paid for 3 cups is ...
3c + 3c·0.08 = 7.29
3.24c = 7.29
c = 7.29/3.24 = 2.25
A cup of coffee costs $2.25.
