Which of the following is the equation of a line in slope-intercept form for a
Triss [41]

Answer:

A

Step-by-step explanation:

Slope m = 2

The point is (0,3)

x1 = 0 and y1 = 3

And y - y1 = m(x - x1)

y - 3 = 2(x - 0)

y - 3 = 2x

y = 2x + 3 this is the equation

If you help with the correct answer u are a god .pt2​
Brrunno [24]

a. Answer:  D: (∞, ∞)

                   R: (-∞, ∞)

<u>Step-by-step explanation:</u>

Theoretical domain is the domain of the equation (without an understanding of what the x-variable represents).

Theoretical range is the range of the equation given the domain.

c(p) = 25p

There are no restrictions on the p so the theoretical domain is All Real Numbers.

Multiplying 25 by All Real Numbers results in the range being All Real Numbers.

a) D: (∞, ∞)

   R: (-∞, ∞)

*********************************************************************************

b. Answer:  D: (0, 200)

                    R: (0, 5000)

<u>Step-by-step explanation:</u>

Practical domain is the domain of the equation WITH an understanding of what the x-variable represents.

Practical range is the range of the equation given the practical values of the domain.

The problem states that p represents the number of cups.  Since we can't have a negative amount of cups, p ≥ 0.  The problem also states that Bonnie will purchase a maximum of 200 cups. So, 0 ≤ p ≤ 200

The range is 25p →  (25)0 ≤ (25)p ≤ (25)200

                             →      0   ≤  25p  ≤  5000

b) D: (0, 200)

   R: (0, 5000)

The equation y = 7x+25 gives the number of minutes it takes to prepare a meal y given the number of people being served x. Which
klemol [59]

<u>Answer-</u> C. For every extra person served, the time it takes to prepare a meal increases by 7  minutes.

<u>Solution- </u>

<em>y = 7x+25</em>

Where y = the number of minutes it takes to prepare a meal

           x = the number of people being served.

If the number of persons increased by one, so x' = (x+1)

Then y' = 7x' + 25 = 7(x+1) + 25 = 7x + 7 + 25 = 7x + 25 + 7 = y + 7

∴ As y gets increased by 7 for every 1 more person , so C is the correct answer.
