After working for 25 hours, Larry made $375. After working for 40 hours, Kyle made $560. Who is paid the better rate? Explain ho

Juliette [100K]

Answer:

Larry.

Step-by-step explanation:

For Larry, do 375/25 = 15. He is getting paid $15 an hour.

For Kyle, you do 560/40 = 14. He is getting paid $14 an hour.

$15 is greater than $14 an hour, so Larry is getting paid at a better rate.

How to do this? (#21 and #23)

Readme [11.4K]

Answer:

$\large\boxed{21.\ g(x)=f(x-2)+1\to g(x)=\log_3(x-2)+1}\\\\\boxed{22.\ g(x)=f(x)-4\to g(x)=3^x-4}\\\\\boxed{23.\ g(x)=-f(x)\to g(x)=-\log_{\frac{1}{2}}x}$

Step-by-step explanation:

f(x) + n - shift the grapf n units up

f(x) - n - shift the grapf n units down

f(x + n) - shift the grapf n units to the left

f(x - n) - shift the grapf n units to the right

-f(x) - reflection about the x-axis

f(-x) - reflection about the y-axis

============================================

Look at the picture.

$21.\\f(x)=\log_3x\\\\g(x)=\log_3(x-2)+1$

move the graph 2 units to the right and 1 unit up

$22.\\f(x)=3^x\\\\g(x)=3^x-4$

move the graph 4 units down

$23.\\f(x)=\log_{\frac{1}{2}}x\\\\g(x)=-\log_{\frac{1}{2}}x$

reflection the graph about the X axis.

The function, f(x)=70n-400, models the profit the instructor of guitar class per month, where n is the number of students enroll

densk [106]

The instructor wants the profit to be positive, so
f(n) > 0
70n -400 > 0
n - 400/70 > 0
n > 5 5/7

The instructor must enroll at least 6 students to make a profit.
