The graph in the top right—-when trying to figure these out, just plug numbers in for x to find the y.
For example: plug 0 in for x on both equations—
2^0 -1=0 so you get it passing thru 0,0
0+2=2 so it passes through 0,2

zysi [14]

It is possible

Group 1 : 684 divided by 36 = 19$

Group 2 : 456 divided by 24 = 19$

Therefore, both groups 1 and 2 charge $19 for each ticket

X-intercept and y-intercepts og y=x^2-3

Rufina [12.5K]

Answer:

Part 1) The y-intercept is the point $(0,-3)$

Part 2) The x-intercepts are the points $(-\sqrt{3},0)\ and\ (\sqrt{3},0)$

Step-by-step explanation:

we have

$y=x^{2}-3$

This is a vertical parabola open upward

step 1

Find the y-intercept

we know that

The y-intercept is the value of y when the value of x is equal to zero

For x=0

$y=(0)^{2}-3$

$y=-3$

The y-intercept is the point (0,-3)

step 2

Find the x-intercepts

we know that

The x-intercept is the value of x when the value of y is equal to zero

For y=0

$x^{2}-3=0$

solve for x

Adds 3 both sides

$x^{2}-3+3=0+3$

$x^{2}=3$

take square root both sides

$x=(+/-)\sqrt{3}$

The x-intercepts are the points $(-\sqrt{3},0)\ and\ (\sqrt{3},0)$

24 over 32 as an equivelent fraction

andrew-mc [135]

12/16,
6/8,
3/4, and
45/60

are all equivalent to 24/32.

Now that I've listed those four, there are
only an infinite number of others remaining.
