LuAnn is playing a math game. She chooses three cards. The value of each of her cards is shown. First card: -12, Second card: 3, Thirds card: -5. What is the sum of the values of LuAnn's three cards?

Answers

Answer: -14

Step-by-step explanation:

Can you please solve this

Answers

Step-by-step explanation:

To get the x intercepts you need to set y = 0.

So you will get:

[tex]x^{2}[/tex] - 4x - 12 = 0

which can then be put in the form of:

(x - 6) (x + 2) = 0

The x intercepts are: (6,0) and (-2,0).

For the vertex you would need to convert the equation to vertex form.

which is : y = a[tex](x-h)^{2}[/tex] =k

[tex]x^{2}[/tex] - 4x - 12 = y

turn it in to square form:

([tex]x^{2}[/tex] - 4x + 4) - 12 - 4 = y

[tex](x-2)^{2}[/tex] - 16 = y

so the vertex is = (2, -16)

If arcLM = 8x-56 and arcNP = 5x+22, find arcLP.

Answers

Answer:

arcLP = 19

Step-by-step explanation:

Given the following

arcLM = 8x-56

arcNP = 5x+22

Required

arcLP

Given that arcLM = arcNP

8x-56 = 5x+22

8x - 5x  = 22 + 56

3x = 78

x = 78/3

x = 26

Let assume arcLP = x - 7

arcLP = 26 -7

arcLP = 19

is it possible to have a regular polygon with measure of each exterior angle as 22

Answers

Answer:

No

Step-by-step explanation:

Number of sides of a polygon = 360°/measure each exterior angle

= 360°/22

= 16.36°

Since, answer is not a whole number, thus, a regular polygon with measure of each exterior angle as 22⁰ is not possible.

Thus the answer is no.

Answer:

No, it is not possible.

Step-by-step explanation:

The sum of the exterior angles = 360

360 divided by 22 = 16.36

As 16.36 is not a whole number an exterior angle of 22 degrees is not possible.

Determine the equation of a line that passes through the point (3,-2) and is PERPENDICULAR to the equation
y= 3x - 1

Answers

y= -1/3x + 5

If the line is perpendicular, it means the slope is negative reciprocal of 3, which is -1/3.

Equation where b (y-intercept) is unknown:
y= -1/3x + b

Replace x with 3 and y with -2 since the line passes through those points.

-2= -1/3(3) + b
-2= -3 + b

Add 3 to both sides of the equation:
1=b, the y-intercept is 1.

The full equation:
y = -1/3x + 1

Aubrey worked at the concession stand during a recent sporting event at her high school. During the first hour of the event, she sold 11 orders of nachos and 18 tacos for a total of 64.95 . During the second hour, she sold 6 orders of nachos and tacos 15 for a total of 43.20.

Answers

Answer:

cost of nachos = $3.45

Cost of tacos = $1.5

Step-by-step explanation:

Let

x = cost of nachos

y = cost of tacos

11x + 18y = 64.95 (1)

6x + 15y = 43.20 (2)

Multiply (1) by 6 and (2) by 11 to eliminate x

66x + 108y = 389.70

66x + 165y = 475.20

Subtract to eliminate x

165y - 108y = 475.20 - 389.70

57y = 85.50

y = 85.50/57

y = 1.5

Substitute y = 1.5 to find x

11x + 18y = 64.95 (1)

11x + 18(1.5) = 64.95

11x + 27 = 64.95

11x = 64.95 - 27

11x = 37.95

x = 37.95/11

x = 3.45

cost of nachos = $3.45

Cost of tacos = $1.5
