Hello! is y = 3x - 3 proportional or non-proportional?? please help!

MissTica

A proportional graph is a straight line that goes through the origin while a non-proportional graph is a straight line that doesn't go through the origin.

y = mx + b

the b represents the y-intercept, so -3 is the y-intercept in the equation y = 3x -3

therefore, the line doesn't go through the origin and is a non-proportional equation

The table below shows the numbers of tickets sold at a movie theater on Friday.

prisoha [69]

Answer:

Number of Adult's tickets sold on Saturday = 3,356

Number of Children's tickets sold on Saturday = 2, 928

Total number of tickets sold over these two days is 8,938.

Step-by-step explanation:

Here, the number of tickets sold on FRIDAY:

Adult Ticket sold = 1,678

Children's Tickets sold = 976

So, the total number of tickets sold on Friday

= Sum of ( Adult + Children's ) tickets = 1,678 + 976 = 2,654 .... (1)

The number of tickets sold on SATURDAY:

Adult Ticket sold = 2 times the number of adult tickets sold on Friday

= 1,678 x 2 = 3,356

Children's Tickets sold = 3 x the number of children's tickets sold on Friday.

= 976 x 3 = 2, 928

So, the total number of tickets sold on Saturday

= Sum of ( Adult + Children's ) tickets = 3,356 + 2,928 = 6, 284 .... (2)

Now, the total number of tickets booked in these two days :

Sum of tickets booked on (Friday + Saturday)

= 2,654 + 6, 284 = 8,938

Hence, total number of tickets sold over these two days is 8,938.

What's the equation of the line passing through the points (3,8) and (-2,-17)?

erma4kov [3.2K]

Answer:

Step-by-step explanation:

1. First the slope: -17-8/-2-3= -25/-5=5

2. What is your line equation now? y=5x+b

3. Replace the x and y value with one of the coordinate points: 8=5(3)+b

4. Solve for b: 8=15+b -7=b

5. Substitute it in the equation: y=5x-7

Hope this helps!

Simplify 18 - 2[x + (x - 5)].

Phoenix [80]

First, distribute what's inside the parenthesis, and change all the subtractions to addition of negatives.

18 + -2 (x^2 + - 5x)

Next distribute the -2

18 + -2x^2 + 10x

Then I like to rearrange stuff to put it in standard form.

-2x^2 + 10x + 18
