Answer:

For part one 30000 and the slope for part two is -2000 and for part three it is y=30000=2000x.

Step-by-step explanation:

If it starts at 30,000 then that is on the 0 on the x-axis.

While the plane is descending by 2000 so that is the slope but because it is descending and not rising it is -2000. If it was rising it would be 2000.

And for part three because it starts and 30000 and it goes down 2000 by the x-axis.

Hope this helps.

I REALLY NEED HELP!!! If someone can answer this quickly and correctly I will give them Brainliest. 1. What is the function rule
Rainbow [258]

Answer:

y= -4x + 3

Step-by-step explanation:

Because the slope is -4/1 which is the same as 4 and 3 is the y-intercept.

Here's the work;

We can just use the first two coordinates which are (0,3) and (1,-1) to get from the x-value 0 to 1 we add 1. and to get from the y-value 3 to -1 we subtract 4. Therefore the slope is -4 and the y- intercept (when x is zero) is 3. Pop that into slope intercept form to get y=-4x +3

Hope that helps and have a great day!

Can someone please help me real quick?
Dima020 [189]

Answer:

3.5p ≤ 40

Step-by-step explanation:

The inequality that best describes this problem is 3.5p ≤ 40;

Given parameters:

Total amount with me = $40

Cost per package of hot dog  = $3.5

Unknown;

The inequality that represents the problem  = ?

Solution:

p is the number of hotdogs that can be bought.

  So, total hotdog that can be bought if each hotdog cost $3.5 per box is;

                    p x 3.5

Now,

    this will equal the total amount at hand;

       p x 3.5 ≤ 40

         3.5p ≤ 40
