Ber [7]

Answer:

f^{-1}(x)=25(x-2)^2

Step-by-step explanation:

The inverse function can be found by solving ...

  f(y) = x

  (√y)/5 +2 = x

  (√y)/5 = x -2 . . . . . subtract 2

  √y = 5(x -2) . . . . . . multiply by 5

  y = 25(x -2)² . . . . . square both sides

The inverse function is ...

  f^{-1}(x)=25(x-2)^2

_____

<em>About the graph</em>

Help me fast PLEASE  The equation y = 1.6x represents the number of laps Henry can swim over time, where y is the number of laps
Phoenix [80]
The table is missing though but you may consider the following calculations :

Y = 1.6 x
for x = 1 minutes
 Y = 1.6 laps
for x = 2 minutes
Y = 3.2 laps
for x = 3 minutes
Y = 4.8 laps

How should i solve this using an algebraic equation
artcher [175]
House price = down payment + mortgage x number of months

430,000 = 250,000 + 2,000x where x is number of months

To find number or months solve for x
430,000 = 250,000 + 2,000x

Subtract 250,000
180,000 = 2,000x

Divide by 2,000
x = 90 months

12 months in one year
90 = 84 + 6 = 12 x 7 + 6

7 years and 6 months

3(x-4) = x + 14<br> How do you solve this equation
Dmitry_Shevchenko [17]

Answer:

x=13

Step-by-step explanation:

you have to isolate the variable

3(x-4)=x+14

distribute

3x-12=x+14

subtract 14 from each side

3x-26=x

subtract 3x from each side

-26=-2x

divide each side by -2

13=x

flip sides

x=13

hope this helps!!! :)
