If f(x)=4x-8, what is f^-1(x)

Mathematics
1 answer:
miv72 [106K]3 years ago
4 0
X = 4x - 8
let's replace x with y.
y = 4x - 8
y + 8 = 4x
x = y/4 + 8/4
x = y/4 + 2
and now replace y with x.
so x = x/4 + 2
and inverse f^-1
f^-1 (x) = x/4 + 2

Find the exact solution of the system of equations of x^2+y^2-4x-6y+4=0 and x^2-4x-3y+4=0
gavmur [86]
We can readily know the x^2-4x+4=3y then use it to replace the same function in the first equation which refers to the 3y+y^2-6y=0 
                                                              y^2-3y=0
                                                             y(y-3)=0
                                                               y1=0 -----------y2=3

Help me answer this please
Marizza181 [45]

Answer:

77 feet below sea level.

Step-by-step explanation:

Since y is the time the submarine is ascending, we can plug it in for y and find our answer. We can create an equation where D is the depth and y is time ascending: D = -230 + 17y

Substitute 9 for y:

D = -230 + 17(9)

D = -230 + 153

D = -77

The depth of the submarine after 9 minutes will be 77 feet below sea level. Hope this helps, and Brainly will be highly appreciated.

Just In case you want explanation-

1. 4 squared Meaning 4 x 4 = 16

3x 6 = 18

96- 18 = 78

in the denominator, 25/ 5 = 5

11 minus 5 = 6

78 divided by 6

it gives you 13
