G(x) = f(x) +5
= 4^x -6 +5
= 4^x -1
The 3rd selection is appropriate.
A)your equation for t-mobile would be
y=20x+100
Topar equation
y=30x
B) you’d set the two equation equal to each other
20x+100=30x
giving you the answer x=10
C) when x>13
D) when x<14
i’m a bit iffy on the last two but that’s the conclusion i came to
160/55.
Simplified version is 32/11
d = r · t ⇒ t = d/r
going
t = 54/(r + 4)
coming
t = 30/(r - 4)
54/(r + 4) = 30/(r - 4) times are equal
54(r - 4) = 30(r + 4) product means/extremes
54r - 216 = 30r + 120 distribute
24r - 216 = 120 subtract 30r from both sides
24r = 336 add 216 to both sides
r = 14 divide both sides by 24
Alfonso bikes at 24 mph.
Subtract to find the amount of the increase:
168 - 140 = 28
The increase in price was $28.
Now divide the amount of increase by the original price.
This will give you a decimal, then multiply the decimal by 100 to get the percent:
28 / 140 = 0.2
0.2 x 100 = 20% increase.
