State the ex and Y intercepts for the given function and then graph the function 2X-3Y=6
Ivahew [28]

Answer:

  a)  (3, 0), (0, -2)

  b)  see below

Step-by-step explanation:

The x-intercept is found by setting y=0 and solving for x:

  2x = 6

  x = 6/2 = 3 . . . point (3, 0), x-intercept

The y-intercept is found by setting x=0 and solving for y:

  -3y = 6

  y = 6/-3 = -2 . . . point (0, -2), y-intercept

__

No. of diners = 240
Musya8 [376]

Answer:

<u>We need to buy 3 cases of juice.</u>

Correct statement and question:

No. of diners = 240 Portions of juice served = 4 oz. per diner Size of juice can = 48 oz. How many cases of juice required if there are 8 cans in a case and you must buy a whole case?

Source:

Previous question that you can search at brainly

Step-by-step explanation:

Let's calculate the number of cases of juice are required this way:

Number of cases required = [(Number of dinners * portion of juice served)/Size of juice can]/Cans in a case

Replacing with the real values, we have:

Number of cases required = [(240 * 4)/48]/8

Number of cases required = [(960)/48]/8

Number of cases required = 20/8

Number of cases required = 2.5

<u>But let's remember that we must buy only whole cases, then we need to buy 3 cases of juice.</u>
