Sometimes a function:
The inverse function of y=x^2 is y=+/-sqrt(x), because remember the negative square of something is the same as the positive square of it.
y=+/-sqrt(x) fails the Vertical line test.
Inverses are only one to one if the original function is a bijection

Solve the following system pf equations

mr Goodwill [35]

Answer:

Step-by-step explanation:

If you need to do this by graphing, you need to change the format of each equation into slope intersect form

start with 3x-2y=-24

-2y=-3x-24

y=-3/2x+12

To graph this, the y intersect (where it crosses the y axis) is 12 and from there the slope is -3/2

For the next equation,

-3x-y=6

-y=3x+6

y=-3x-6

So the y intersect is -6 and the slope is -3.

Once you graph both of these, the point where both lines cross AKA the intersecion is the solution to the problem.

Answer:

$4\frac{7}{8}$

Step-by-step explanation:

The three heaviest eggs are between $1\frac{1}{2}$ and $1 \frac{3}{4}$

$1\frac{1}{2} +1 \frac{3}{4}/2$
$1+1+\frac{2}{4}+\frac{3}{4}/2$
$2\frac{5}{4}/2$
$1\frac{5}{8}$

$1\frac{5}{8}*3=\frac{13}{8}*3=\frac{39}{8} = 4\frac{7}{8}$

Hope this helps and please feel free to comment, ask questions, give feedback, and correct me if I am wrong!

Have a great day!
