Answer:

x = 3/8 or 0.375

Step-by-step explanation:

For this equation, you need to set it up so it's easier to work with. For example, 3x + x - 3 ÷ 2 = 0. Next, use the order of operations which is the acronym PEMDAS.

P = parentheses (first if there is any)

E = exponents (if there is any)

M/D = Multiply or Divide

A/S = Add or Subtract

Since we have a division problem to do, we need to simplify the division first based on the order of operations.

3x + x <u>- 3 ÷ 2 </u>= 0. -3 ÷ 2 is equal to -1.5. Every division problem is also a fraction. Next, you will have left 3x + x - 1.5 = 0. When you have both subtraction and addition in the equation, all you have to do is solve from left to right. There is an addition problem to solve first then the subtraction problem. For example: <u>3x + x</u> - 1.5 = 0, which equals to 4x - 1.5 = 0. Next, you add 1.5 to -1.5 and 0. Anything added or subtracted by a number and it's opposite will always equal 0. For example: 4x <u>- 1.5 + 1.5</u> =<u> 0 + 1.5. </u> You have to get rid of the -1.5 and 1.5 since it equals 0. This will be left with 4x = 1.5. Divide both sides by 4 to balance the equation. For example: <u>4x ÷ 4 = 1.5 ÷ 4. </u>Do you see that the 4's on one side cancel each other out? You are left with x = 3/8.

Volgvan

<h3>Answer:</h3>

b. The side length of a cube is dependent on the volume.

<h3>Step-by-step explanation:</h3>

The function definition V(s) means the volume (V) is dependent upon the side length (s), <em>not the other way around</em>.

A line passes through the points (2,4) and (5,6) .

Alenkinab [10]

Answer:

Option B and D are correct.

Step-by-step explanation:

Given: A line passes through the points (2,4) and (5,6).

* Case 1:

If a line passes through the points (2, 4) and (5, 6)

Point slope intercept form:

for any two points $(x_1,y_1)$ and $(x_2, y_2)$

then the general form $y -y_1=m(x-x_1)$ for linear equations where m is the slope given by:

$m =\frac{y_2-y_1}{x_2-x_1}$

First calculate slope for the points (2, 4) and (5, 6);

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{6-4}{5-2} = \frac{2}{3}$

then, by point slope intercept form;

$y-4=\frac{2}{3}(x-2)$

* Case 2:

If a line passes through the points (5, 6) and (2, 4)

First calculate slope for the points (5, 6) and (2, 4);

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-6}{2-5} = \frac{-2}{-3}= \frac{2}{3}$

then, by point slope intercept form;

$y-6=\frac{2}{3}(x-5)$

Yes, the only equation of line from the given options which describes the given line are;

$y-4=\frac{2}{3}(x-2)$ and $y-6=\frac{2}{3}(x-5)$
