No, the measurements in the table given are not showing equivalent proportional relationships.

Proportional relationships are relationships between two variables where their ratios are equivalent.

Given is a table showing, Proportional relationships for four serving of pineapple-mango juice,

           Pineapple juice                                           Mango juice

                       2                                                                [tex]1\frac{1}{9}[/tex]

                      [tex]2\frac{1}{2}[/tex]                                                                4

                       3                                                                [tex]4\frac{1}{2}[/tex]

Checking for proportional relationships;

1) Pineapple juice / Mango juice = 2 ÷ 10/9 = 9 / 5

2) Pineapple juice / Mango juice = 5 / 2 ÷ 4 = 5 /8

3) Pineapple juice / Mango juice = 3 ÷ 9/2 = 2 / 3

As we see, that all three proportions are not equal.

Hence, we can that the given relations are not equivalent proportional relationships.

Answer:

[tex]y - 220x = -6405[/tex]

Step-by-step explanation:

Given

[tex]Rate = 220[/tex]

At [tex]time = 33\ hours[/tex], [tex]gallons = 855[/tex]

Required

Determine the equation

The rate means slope (m).

So:

[tex]m = 220[/tex]

From the question, x represents time and y represents the amount of water.

So:

[tex]x=33[/tex] when [tex]y = 855[/tex]

Or:

[tex](x_1,y_1) = (33,855)[/tex]

The equation is determined using:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 855 = 220(x - 33)[/tex]

[tex]y - 855 = 220x - 7260[/tex]

Collect Like Terms

[tex]y - 220x = 855 - 7260[/tex]

[tex]y - 220x = -6405[/tex]

Hence, the equation in standard form is:

[tex]y - 220x = -6405[/tex]

Answer:

x = -1

Step-by-step explanation:

y + 2x = -1

Subtract 2x from both sides;

y = -2x - 1

y = 3x + 4

-2x - 1 = 3x + 4

Subtract 3x from both sides;

-5x - 1 = 4

Add 1 to both sides;

-5x = 5

Divide both sides by -5

x = -1

Using the Pythagorean theorem, the length of the line is: √45 = 6.7 units.

The Pythagorean theorem is the equation that describes how the lengths of the three sides of a right triangle relate to each other. If a and b are smaller legs, and c us the hypotenuse of the triangle, the Pythagorean theorem states that:

c² = a² + b².

Consider the line above to be the hypotenuse of a right triangle that is formed by the rise and run of the line.

Rise = a = 3 units

Run = b = 6 units

Line = c

Therefore:

c² = 3² + 6²

c² = 9 + 36

c² = 45

c = √45

c = 6.7 units.

Question:

Determine the value of m and n so that the following system of linear equation have an infinite number of solutions.

[tex](2m-1)x+3y-5=0[/tex]

and

[tex]3x+(n-1)y-2=0[/tex]

Answer:

[tex]m=\frac{17}{4}[/tex]

[tex]n = \frac{11}{5}[/tex]

Step-by-step explanation:

Given

[tex]3x+(n-1)y-2=0[/tex]

[tex](2m-1)x+3y-5=0[/tex]

Rewrite both equations:

[tex]3x + (n - 1)y = 2[/tex]

[tex](2m - 1)x + 3y = 5[/tex]

For the expression to have a solution, the following condition must exist:

[tex]\frac{3x}{(2m - 1)x} = \frac{(n-1)y}{3y}= \frac{2}{5}[/tex]

Split to 2

[tex]\frac{3x}{(2m - 1)x} = \frac{2}{5}[/tex]

[tex]\frac{(n-1)y}{3y}= \frac{2}{5}[/tex]

Cross Multiply

[tex]5 * 3x = 2 * (2m - 1)x[/tex] -- (1)

[tex]5 * (n -1)y = 2 * 3y[/tex] -- (2)

Solving (1)

[tex]5 * 3x = 2 * (2m - 1)x[/tex]

Divide both sides by x

[tex]5 * 3 = 2 * (2m - 1)[/tex]
