Step-by-step explanation:

f(g(10))

This is called a composite function. It's when you plug one function into another.

First, find g(10):

g(x) = √(x-9)

g(10) = √(10-9)

g(10) = √1

g(10) = 1

Then plug that into f(x):

f(x) = -9x - 9

f(g(10)) = -9 g(10) - 9

f(g(10)) = -9 (1) - 9

f(g(10)) = -9 - 9

f(g(10)) = -18

vaieri [72.5K]

This can be solve by establishing equations.
let x be the miles mrs. storey drove
y be the miles mr storey drovee

the first equation is
y = 3x

second equation
x + y = 3200
then substitute equation 1

x + 3x = 3200
4x = 3200
x = 800 miles mrs storey drove

37,253,956 what is the value of the first 5 in California population 10 times as great as the value of the second 5? Explain

Vadim26 [7]

The value of the first 5 is only 50 people. The second 5 is worth 50,000. So if 50 was ten times greater it would still be less because that only equals 500.

So No it isn't .

It usually took josh 2/5 of an hour to ride his bike to work. But on Monday, his bike was broken, so he took the bus to work whi

Snezhnost [94]

Answer: taking the bus to work takes 13 minutes longer.

Step-by-step explanation:

It usually took josh 2/5 of an hour to ride his bike to work. This means that the number of hours that it took Josh to ride his bike to work is

2/5 × 60 = 24 minutes

But on Monday, his bike was broken, so he took the bus to work which took 5/8 of an hour. This means that the amount of time that it took Josh spent on the bus to work is

5/8 × 60 = 37.5 minutes

The difference between the time spent riding the bike and time spent on the bus is

37.5 - 24 = 13 minutes
