You want to leave a 15% tip on a meal that cost $65.00.

First, convert the 15% to an actual number that can be used in a calculation. For percents,this is always done by simply dividing the percent (in this case 15%) by 100%.So, the conversational term "15%" becomes 15% / 100% = 0.15 in terms of a real mathematical number.

Second, you need to find out what 15% of your $65.00 meal cost is.This is always done by multiplying 0.15 by $65.00, or

0.15 x $65.00=$9.75.

So, the amount of tip you are going to leave is $9.75.

This makes the total cost of your meal (to write on your charge slip or other payment)

$65.00 + $9.75 = $74.75.

x=-17, y=5. (-17, 5).

Step-by-step -2x-5y=9

3x+11y=4

---------------

3(-2x-5y)=3(9)

2(3x+11y)=2(4)

---------------------

-6x-15y=27

6x+22y=8

-----------------

7y=35

y=35/7

y=5

3x+11(5)=4

3x+55=4

3x=4-55

3x=-51

What value of m does the graph y = 18x2 + mx + 2 have exactly one x-intercept?

Vlada [557]

To get the graph to have one x-intercept, we must find the m value where the discriminant of the equation will equal 0.

The discriminant for a graph with one x-intercept is found with the following formula:

$b^2 - 4ac = 0$

Plug in the values of the equation into this formula:

$\text{a = 18, b = m, c = 2}$
$m^2 - 4(18)(2) = 0$
$m^2 - 144 = 0$

Add 144 to both sides:

$m^2 = 144$

Square root both sides to get m by itself:

$\sqrt{144} = \pm 12$
$m = 12, \ m = -12$

In order for the graph to have one x-intercept, m must equal -12 or 12.
