Find the inverse of each given functions.<br> f(x) = 4x − 12

Paha777 [63]

Answer:

y=1/4x+3

Step-by-step explanation:

To find the inverse, switch x and y or f(x)

f(x)=4x-12

y=4x-12

x=4y-12

Add 12 to both sides

x+12=4y-12+12

x+12=4y

Divide both sides by 4

x+12/4=y

1/4x+12/4=y

1/4x+3=y

y=1/4x+3

8 cleaners can clean an office in 3 hours,if the block needs to be cleaned in 2 hours,how many cleaners will be needed?

romanna [79]

Answer:

12 cleaners

Step-by-step explanation:

8 cleaner can clean in 3 hours = 1 office

1 cleaner can clean in 3 hours = $\frac{1}{8}$ part of job

1 cleaner can clean in 1 hours = $\frac{1}{3 \times 8}$ part of job

Let the number of cleaner required to finish the job in 2 hours = x

hence

x cleaner can clean in 1 hours = $\frac{1 \times x }{24}$ part of job

x cleaner can clean in 2 hours = $\frac{2 \times x }{24}$ part of job

Hence

$\frac{2 \times x }{24}=1$

$\frac{2x}{24}=1$

$2x=24$

$x=12$

Hence we need 12 men to complete the same job in 2 hours
