Write the standard form of the line with the given information. Include your work in your final answer. Type your answer in the
AURORKA [14]

Answer:

The standard form of line is

-3x+y=-2

Step-by-step explanation:

we are given a line

slope=3

so,

m=3

y-intercept of -2

so,

b=-2

now, we can use slope-intercept form of line

y=mx+b

now, we can plug values

y=3x-2

we can write it in standard form of line

ax+by=c

y=3x-2

we can subtract both sides by 3x

y-3x=3x-2-3x

y-3x=-2

-3x+y=-2

So, the standard form of line is

-3x+y=-2

The manager at a concert venue keeps track of the number of adult tickets and student tickets sold each day and the total money
poizon [28]

Answer: the number of adult and student tickets sold are (45, 29)

Step-by-step explanation:

Let x represent the number of adult tickets that were sold.

Let y represent the number of student tickets that were sold.

On Wednesday, a total of 74 tickets were sold. This means that

x + y = 74

x = 74 - y- - - - - - - - - - - - - - 1

If adult tickets are sold for $15 and student tickets are sold for $11 and the money collected was $994, it means that

15x + 11y = 994- - - - - - - - - - - - - - 2

Substituting equation 1 into equation 2, it becomes

15(74 - y) + 11y = 994

1110 - 15y + 11y = 994

- 15y + 11y = 994 - 1110

- 4y = - 116

y = - 116/ - 4

y = 29

Substituting y = 29 into equation 1, it becomes

x = 74 - 29 = 45
