What is the inverse of the function below? f(x)= x/3 -2

Mathematics

pychu [463]3 years ago

Answer:

The inverse is g(x) = 3x + 6

Step-by-step explanation:

f(x) = x/3 - 2

y = x/3 - 2

To find the inverse, swap x and y, then put it in y = mx + b

x = y/3 - 2

y/3 = x + 2

y = 3x + 6

g(x) = 3x + 6

PIT_PIT [208]

Set up two equations:

1st:  P (for Price family) + J (for Jenkins family) = 45 hours

2nd: 20P + 35J = 1200 liters

Rewrite the first equation as P = 45 – J

Replace P in the second equation:

20(45-J) + 35J = 1200

Simplify:

900 -20J + 35J = 1200

900 +15J = 1200

Subtract 900 from both sides:

15J = 300

Divide both sides by 15:

J = 300/15

J = 20

Jenkins used theirs for 20 hours

Price used theirs for 45-20 = 25 hours.

lana [24]

Answer:

UW=14

Step-by-step explanation:

First we know that UV+VW=UW, so:

4+x+10=2x+14

Solve for x first:

x+10=2x+10

10=x+10

x=0

Then, substitute the X

2(0+14)=14=UW

To check your answer, substitute and add UV and VW

4+(0)+10

14

erik [133]

Answer:

x=-0.08 and y=2.92

Step-by-step explanation:

123x + 2(x+3) = -4             y = -0.08 + 3

123x + 2x + 6 = -4                = 2.92

125x + 6 = -4

125x = -10

x= -0.08
