[tex]-\frac{b}{2a}=-\frac{12}{-4}=3[/tex]

axis of symmetry(x-value of the vertex): [tex]x=3[/tex]

input this value into the function to get the vertex

[tex]-2(3)^{2}+12(3)+5[/tex]

[tex]-18+36+5[/tex]

[tex]18+5[/tex]

[tex]23[/tex] is the y-value of the vertex

Answers

Answer:

Step-by-step explanation:

Slope m is defined as m=(y2-y1)/(x2-x1) in this case

m=(218-155)/(22-15)=63/7=9

y=mx+b

y=9x+b, using point (15,155) we can solve for the y intercept b

155=9(15)+b

155=135+b, b=20 so the line is

y=9x+20

In thirty days there will be

y=9(30)+20=290 coins

One month Mai rented 12 movies and 2 video games for a total of $53. The next month she rented 3 movies and 5 video games for a total of $38. Find the rental cost for each movie and each video game.

Answers

Answer:

Movie cost $3.5 and the video game cost $5.5

Step-by-step explanation:

Given data

Let the cost of movies be x

and the cost of video game be y

12x+2y= 53----------1

and

3x+5y= 38-----------2

solve 1 and 2

12x+2y= 53X 5

3x+5y= 38  X2

 60x+10y= 265

- 6x+10y= 76

 54x= 189

x= 189/54

x= $3.5

put x= 3.5 in  1

12(3.5)+2y= 53

42+2y= 53

2y= 53-42

2y= 11

y= 11/2

y= $5.5

Hence the movie cost $3.5 and the video game cost $5.5

Two line segments intersect at point B as shown.
What is the measure of angle ABC?

Answers

Answer:

the answer is b.) 24

Step-by-step explanation:

you would set 3x + 12 and 6x equal because they have the same angle

[tex]3x + 12 = 6x[/tex]

then subtract 12 on both sides

[tex]3x = 6x - 12[/tex]

then subtract 6x from both sides

[tex] - 3x = - 12[/tex]

now just divide by 3 on both sides

[tex]x = 4[/tex]

then add it into the equation 3(4) + 12

The requried measure of angle ABC is 24°. Option B is correct.

What are the angle?

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,
For two intersecting lines alternate angle is always equal.
3x + 12 = 6x
3x = 12
x = 4

Now,
6x = 6(4) = 24°

Thus, the requried measure of angle ABC is 24°. Option B is correct.
