Solve the system:
22-4y= 14
3y + 5z =9
a. or = 1, y=1
b. or = 1, y=-
c.or=3, y=2
d.o2 = 5, y=-1

Step-by-step explanation:

Given the following system of equations:

You can follow these steps to solve it using the Substitutiong method:

1. Solve for "y" from the first equation in order to finds its value:

2. Substitute the value for "y" into the second equation and solve for "z" in order to find its value. This is:

 -1

f     (x)  = sqrt(x - 3)

Step-by-step explanation:

Hope you won't mind the correction, but that's y = x^2 + 3.  Use " ^ " to indicate exponentiation.

Starting with y = x^2 + 3, interchange x and y:

x = y^2 + 3

Next, solve for y:  y^2 = x - 3, or y = +sqrt(x - 3).

Note that we'd normally write "plus or minus sqrt(x - 3)," but that would provide two y values for each x value (which violates the definition of "function').

Finally, replace "y" with the inverse function label:

 -1

f     (x)  = sqrt(x - 3)
