The approximate volume in milliliters, y, for a volume of x fluid ounces is equal to 29.57 times the value of x. Which table rep
Angelina_Jolie [31]

The table which represents the relationship is:

Fluid ounces, x            Volume y ( in millimeters)

       1                                       29.57

       2                                      59.14

       3                                      88.71

       4                                     188.28

In mathematics, a relation describes how two distinct sets of information related to one another. If more than two non-empty sets are taken into consideration, a connection between their elements will indicate that more than two sets are being evaluated.

Let y be the volume of fluid x in millimeters.

Now, y is equal to 29.57 times the value of x.

Therefore,

y = 29.57 × x

y = 29.75x

So, when x = 1:

y = 29.75(1) = 29.57

When x = 2,

y = 29.57(2) = 59.14

When x = 3,

y = 29.57(3) = 88.71

When x = 4,

y = 29.57(4) = 118.28

Therefore, the table that represents the relationship is:

Fluid ounces, x            Volume y ( in millimeters)

       1                                       29.57

       2                                      59.14

       3                                      88.71

       4                                     188.28

Find the equation lines<br> (4, 5)(7, 3)
mash [69]

Step-by-step explanation:

Hey there!

The equation of a st.line passing through points (4,5) and (7,3) is;

(y - y1) =  \frac{y2 - y1}{x2 - x1} (x - x1)

<u>Put</u><u> </u><u>all values</u><u>. </u>

<u>(y - 5) =  \frac{3 - 5}{7 - 4} (x - 4)</u>

<u>Simplify</u><u> </u><u>it</u><u>. </u>

<u>(y - 5) =  \frac{ - 2}{3} (x - 4)</u>

<u>3(y - 5) =  - 2x + 8</u>

<u>3y - 15 =  - 2x + 8</u>

<u>2x + 3y - 23 = 0</u>

<u>Therefore the</u><u>required</u><u> </u><u>equation</u><u> </u><u>is</u><u> </u><u>2</u><u>x</u><u>+</u><u>3</u><u>y-23</u><u>=</u><u>0</u><u>.</u>

<em><u>Hope it helps</u></em><em><u>.</u></em><em><u>.</u></em>

The sum of 5 times the width of a rectangle and twice its length is 26 units. The difference of 15 times the width and three tim
Zinaida [17]

Answer: length = 8 units

Width = 2 units

Step-by-step explanation:

Let the length of the rectangle be represented by L

Let the width of the rectangle be represented by W

The sum of 5 times the width of a rectangle and twice its length is 26 units. This means that

5W + 2L = 26 - - - - - - - - 1

The difference of 15 times the width and three times the length is 6 units. It means that

15W - 3L = 6 - - - - - - - - 2

The system equations are equation 1 and equation 2.

Multiplying equation 1 by 3 and equation 2 by 2, it becomes

15W + 6L = 78

30W - 6L = 12

Adding both equations,

45W = 90

W = 90/45 = 2

15W - 3L = 6

15×2 - 3L = 6

-3L = 6 - 30 = - 24

L = - 24/ -3 = 8
