Write an equation of the line in slope-intercept form.

Mathematics

Answer:

y=mx+b where m is the slope and b is where the line crosses the y axis.

THe line crosses the y axis at 0, 2 so 2 = b

the slope is how many units the point goes up/down and to the left/right from the y intercept. From 0, 2 to 3, 3 the point goes up 1 and over to the right 3 times. rise/run is slope so 1/3 is the slope:

y=1/3x+2

Answer:

Y= -1/3x + 4

Step-by-step explanation:

Slope equation= y2 - y1/x2 -x1

Subtract 2-3/ 0-3 = -1/3

Choose an ordered pair to use for this problem. I chose 3,3.

Y-intercept equation- y = mx + b

3 = -1/3 * 3 + b

Multiply-1/3 * 3

3 = -1 + b

Add 1 to get rid of -1 and get b alone

3 + 1 = -1 + 1 +b

4= b

Now plug in your numbers to your equation.

Y= -1/3x + 4

Admission for a movie is $8 for children and $12 for adults. On a certain day, 3200 people attend the movie theater and $33,040
Nezavi [6.7K]
Let us assume the number of children attending the movie = x
Let us also assume the number of adults attending the movie = y
Cost of admission for a children in the movie = $8
Cost of admission of an adult in the movie = $12
Number of people going to the movie on a certain day = 3200
Total amount collected from the movie theater = $33040
Then
x + y = 3200
And
8x + 12y = 33040
2x + 3y = 8260
Let us first take the equation
x + y = 3200
x = 3200 - y
Now we will put the value of x in the equation
2x + 3y = 8260
2(3200 - y) + 3y = 8260
6400 - 2y + 3y = 8260
y = 8260 - 6400
   = 1860
Now we will put the value of y from the above deduction in the equation
x + y = 3200
x + 1860 = 3200
x = 3200 - 1860
   = 1340
So the number of children going to the movie theater is 1340 and the number of adults going to the movie theater is 1860.

A diver jumps off a 20 foot high diving board with an initial upward velocity of 4 feet per second. Use the vertical motion mode
Pachacha [2.7K]

The height is represented by h = -16t² + 4t + 20 and There is only one solution, because the solutions indicate time and time cannot be negative.

<h3>How to solve vertical motion models?</h3>

We are given the vertical model of the diver's jump as;

h = -16t² + vt + s

where;

h is height

t is time

v is velocity

s is distance

A) We are given;

Distance; s = 20 ft

velocity; v = 4 ft/s

Thus;

h = -16t² + 4t + 20

B) The solution of the model is gotten from;

-16t² + 4t + 20 = 0

Solving this quadratic equation gives;

t = 1.25 seconds or -1 second

C) B. There is only one solution, because the solutions indicate time and time cannot be negative.
