Question 7 which graph represents a function

Answers

Answer 1

Answer:

Where are the graphs?

Step-by-step explanation:

Anyway use this method.

Use the vertical line test to determine whether or not a graph represents a function. If a vertical line is moved across the graph and, at any time, touches the graph at only one point, then the graph is a function. If the vertical line touches the graph at more than one point, then the graph is not a function.

Family Video charges $10 for
a monthly membership and
$2.50 per movie. Babe's
Movies charges a $12
membership and $2 per
movie. How many movies
must be rented before the
price is the same at both
stores? What is the cost?

Answers

Answer:

4 movies, $20

Step-by-step explanation:

Given data

Family Video

charges $10 for a monthly membership and

$2.50 per movie

let the number of movies be x

and the charge for x movies be y

y= 10+2.5x----------1

Babe's  Movies

charges a $12

membership and $2 per

movie.

let the number of movies be x

and the charge for x movies be y

y= 12+2x----------2

equate 1 and 2

10+2.5x= 12+2x

collect like terms

12-10= 2.5x-2x

2= 0.5x

x= 2/0.5

x= 4 movies

put x= 4 in equation 1 or 2

y= 12+2x----------2

y= 12+2*4

y= 12+8

y= $20

y = x - 4. 2x + 3y = -17 substitution method

Answers

Answer:

x = -1

y = -5

Step-by-step explanation:

y = x - 4                                     y = x - 4

2x + 3y = -17                             y = (-1) - 4

2x + 3(x - 4) = -17                      y = -1 - 4

2x + 3x - 12 = -17                       y = -5

5x - 12 = -17

5x - 12 + 12 = -17 + 12                 Check

5x = -5                                    2x + 3y = -17

5x/5 = -5/5                           2(-1) + 3(-5) = -17

x = -1                                        -2 + -15 = -17

                                                   -17 = -17

507 people use the public swimming pool , the daily price for children is 1.75 and the price for adults is 2.25 and the admission total was 971.75 how many children were at the public pool

Answers

Answer: 338 children

Step-by-step explanation:

Assume the children are represented by x and the adults are y.

Relevant equations will be:

x + y = 507 people

1.75x + 2.25y = 971.75

y = 507 - x

1.75x + 2.25 * ( 507 - x) = 971.75

1.75x + ‭1,140.75‬ - 2.25x = 971.75

1.75x - 2.25x = 971.75 - ‭1,140.75‬

-0.5x = -169

x = -169/-0.5

x = 338 children

Adults = 507 - 338

= 169 adults
