Answer:

D has the same y-intercept

Step-by-step explanation:

<em>y-intercept of the function in the question is -3.</em>

<u>A) 2/3 x + 3y = -3</u>

<em>Make y the subject</em>

3y = -2/3x-3

y = -2/9-1

<em>The y-intercept is -1; it is not the same.</em>

<u>B) -2/3 x + 3y = 6</u>

<em>Make y the subject</em>

3y = 2/3x + 6

y = 2/9x + 2

<em>The y-intercept is 2; it is not the same.</em>

<u>C) x + 4y = 12</u>

<em>Make y the subject</em>

4y = -x + 12

y = -x + 3

<em>The y-intercept is +3; it is not the same.</em>

D) 6x - 7y = 21

Make y the subject

7y = 6x - 21

y = 6/7x - 3

The y-intercept is -3; it is the same.

Therefore, option D has the same y-intercept as the function given in the question.

Answer:

Option D.

Step-by-step explanation:

The given function is

y=\frac{2}{3}x-3

Substitute x=0 in the given function to find the y-intercept.

y=\frac{2}{3}(0)-3=-3

The y-intercept of the given function is -3. We need to find the equation whose y-intercept is -3.

Substitute x=0 in the given each of the equations to find the y-intercepts of those equation.

First equation is

\frac{2}{3}x+3y=-3

\frac{2}{3}(0)+3y=-3

3y=-3

y=-1

y-intercept is -1.

Second equation is

-\frac{2}{3}x+3y=6

-\frac{2}{3}(0)+3y=6

3y=6

y=2

y-intercept is 2.

Third equation is

x+4y=12

(0)+4y=12

4y=12

y=3

y-intercept is 3.

Fourth equation is

6x-7y=21

6(0)-7y=21

-7y=21

y=-3

y-intercept is -3.

Therefore, the correct option is D.

Tell whether the two quantities vary directly. Explain your reasoning. The cafeteria provides three meals per day.
Dafna11 [192]

Answer:

The cafeteria provides three meals per day.

<u>Reason 1</u>

Yes, they vary directly  

As number of days increases ,Total number of meals i.e

1st day ⇒ 3

2nd day⇒6

3 rd day⇒9

4th day⇒12

......................

.........................

increases.

Total number of Meals = k×Number of days

But there is another possibility also

<u>Reason 2</u>

1 st day ⇒ 3

2nd day ⇒3

3rd day⇒ 3

.....................

.....................

As you can see from the above expression On each day number of meals is  

constant.

So we can say that ,

On each Day=Constant amount of meal=3

So, there is no Proportionality between Days and Meal.

Find The Value x ~<br><img src="https://tex.z-dn.net/?f=%20%5Clarge%20%5Csf%20%5Cunderline%20%5Cbold%7B4x%20%2B%2026%20%3D%2016%
Nikitich [7]

The value of x in the algebraic equation is: -5/2.

<h3>How do you Find the Value of a Variable in an Algebraic Equation?</h3>

Given an algebraic equation, to find the unknown value of x, solve by isolating x in the equation.

Given:

4x + 26 = 16

Subtract 26 from both sides

4x = 16 - 26

4x = -10

Divide both sides by 4

x = -10/4

x = -5/2

Therefore, the value of x in the algebraic equation is: -5/2.
