Answer:

E

Step-by-step explanation:

The equation of proportion is

y = kx ← k is the constant of proportionality and

k = \frac{y}{x}

Substitute the values from the table into the equation for k, that is

k = \frac{2}{3} = \frac{4}{6} = \frac{6}{9} = \frac{2}{3}

Y is directly proportional to x.
Brums [2.3K]
If y is directly proportional to x then y:x.
When y = 30, x = 6 then 30/6 = 5:1. Therefor for every 1x there is 5y vice versa. When x = 12, then y = 5 * 12 = 60.
Therefore y = 60 hence 60:12

Which of the points listed below is not on the line with equation 7y+2=3x-5
kicyunya [14]

Answer: Second option.

Step-by-step explanation:

Given the folllowing Linear Equation:

7y+2=3x-5

You need to substitute the coordinates of each point given in the options into the equation and then evaluate.

1) Substituting  (2, -\frac{1}{7}) into the equation, you get:

7(-\frac{1}{7})+2=3(2)-5\\\\-1+2=6-5\\\\1=1\ (TRUE)

2) Substituting the point (3, -\frac{3}{7}). you get:

7(-\frac{3}{7})+2=3(3)-5\\\\-3+2=9-5\\\\-1=4\ (FALSE)

3) Apply the same procedure using the point (1, -\frac{4}{7}):

 7(-\frac{4}{7})+2=3(1)-5\\\\-4+2=3-5\\\\-2=-2\ (TRUE)

4)  Apply the same procedure using the point (-1, -\frac{10}{7})

 7(-\frac{10}{7})+2=3(-1)-5\\\\-10+2=-3-5\\\\-8=-8\ (TRUE)

5) Substituting  (0,-1) into the equation:

 7(-1)+2=3(0)-5\\\\-7+2=-0-5\\\\-5=-5\ (TRUE)

Therefore, the point (3, -\frac{3}{7})  is not on the given line.

The pond can hold 400 water lilies. By what day will the pond be full? Write and solve an equation. The pond will be full by the
egoroff_w [7]

The pond will be full by the end of the day in 93 days.

<h3>Linear system</h3>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

The pond can hold 400 water liters.

y = 3.915(1.106)x is an expression.

<h3>To find </h3>

The pond will be full by the end of the day.

<h3>How many days it will take?</h3>

Let x be the day and y be the hold of water.

When pond can hold 400 liters of water the x will be

400 = 3.915×1.106x

400 = 4.33 x

    x = 92.37 ≈ 93

Thus, the pond will be full by the end of the day in 93 days.

More about the linear system link is given below.
