Explain how you would graph the line -3x - y = 9 using intercepts.

Answers

Start by rearranging the question around where it’s y= so it would be y= 3x-9. Go down to -9 and place a point there, after go up three spots and move 1 point to the right. Keep doing that until you get your linear graph.
Hope that helped (:
-y=3x+9
y=-3x-9

it would be a line with a y intercept of -9 going up 3 and left 1 or down 3 and right 1 over and over again. it’s also linear

Answer:

Step-by-step explanation:

Let x=number of pencil boxes, and let y=packs of index cards

Part A: 39=1.95x

x=20

Part B: 20 x 12 = 240 pencils

Part C: 48=4.8y

y=10

Part D: 10 x 200 = 2000 index cards

Part E: Arnold and Phillip can create 80 bags of 3 pencils and 25 note cards.

A corn vendor at a farmer's market was selling a bag of 8 ears of corn for $2.56. Another vendor was selling a bag of 12 for $4.32. Which bag is the better deal? Explain or show your reasoning.

First one because if you cut it down you can get 12 corn for a dollar less.

An amusement park’s goal is to sell 1 million tickets within the first four months of its being open.


How many more tickets does the park need to sell in Month 4 to reach this goal?

About how many tickets will the park need to sell in Month 4?

≈______ tickets.

Answers

Answer:

look at the explenation

Step-by-step explanation:

Hello! does it say how many have already been sold? if not then each month is 250,000 tickets

The amusement park needs to sell 250,000 more tickets in Month 4 to reach its goal of 1 million tickets in four months.

We can calculate the average number of tickets the amusement park needs to sell each month in order to determine how many more tickets they need to sell in Month 4 in order to meet their target of selling 1 million tickets within the first four months.

1,000,000 tickets ÷ 4 months = 250,000 tickets per month

250,000 tickets per month × 3 months = 750,000 tickets sold in the first three months

1,000,000 tickets goal - 750,000 tickets sold = 250,000 more tickets needed in Month 4

To reach its objective of selling 1 million tickets within the first four months, the theme park needs to sell 250,000 more tickets in Month 4.

average monthly target ≈ 250,000 tickets.

I believe it is C

Step-by-step explanation:

Since it goes from 0 to 4 that means it has to start with a positive 4 so A and B are out. then it ends at -4 and the difference between 4 and -4 is 8 so it has to be a difference of 8(-8). Therefore, it becomes 4-8=C

The graph below represents the height of a golf ball in feet as a function of the elapsed time since it was hit. The golf ball was in the air for 4 seconds.
What are the domain and range of the representative function?
A)Domain: 0 ≤ x ≤ 4
Range: 0 ≤ y ≤ 80
B)Domain: 0 < x < 80
Range: 0 < y < 4
C)Domain: 0 < x < 4
Range: 0 < y < 80
D)Domain: 0 ≤ x ≤ 80
Range: 0 ≤ y ≤ 4

Answers

Answer:

It´s A

Step-by-step explanation:

You can eliminate B and D because the ¨x¨  would be 4 not 80 because it´s on the x-axis not on the y-axis. Secondly whenever you have a graph you need to have the less than or equal to sign with the line under.

Hope this helps :)

The domain and range of the representative function should be option A. Domain: 0 ≤ x ≤ 4

Range: 0 ≤ y ≤ 80

What are domain and range?

The domain of a function represent the set of values that should be permitted for putting into the function. In this set, the x values in the function like f(x). Here the range of the function represent the amount set where the function should be presumed.

Therefore, based on the given graph the correct option is A.

Step-by-step explanation:

Angle 4 is congruent to angle 8. This is enough information to prove that 'u' parallel to 'v'.

What are parallel lines?

For a pair of lines, the perpendicular distance is equal at every point, then the pair of lines are called parallel lines.

The given information are:

1. Angle 2 is congruent to angle 4.

Angle 2 and Angle 4 are opposite angles. They are always equal.

This information does not prove that 'u' parallel to 'v'.

2. Angle 4 is congruent to angle 8.

Angle 4 and Angle 8 are corresponding angles.

This information proves that 'u' parallel to 'v'.

Angle 6 + angle 7 = 180 degrees.

The sum of the angle 6 and angle 7 are always 180 degrees.

This information does not prove that 'u' parallel to 'v'.

Angle 3 + angle 4 = 180 degrees

The sum of the angle 6 and angle 7 are always 180 degrees.

This information does not prove that 'u' parallel to 'v'.
