Answer:

x = -4

Step-by-step explanation:

−6 − 3 = 21

−6 − 3 + 3 = 21 + 3

= −4

The solution to the equation -6x - 3 = 21 is x = -4.

We must separate the variable x on one side of the equation in order to determine the answer to the equation -6x - 3 = 21.

Here's how to accomplish that:

Step 1: Add 3 to both sides of the equation to start moving the constant term (in this example, -3), which is the first step:

-6x - 3 + 3 = 21 + 3

To put it simply, we have:

-6x = 24

Step 2: Subtract -6 from both sides of the equation to find the value of x:

(-6x) / -6 = 24 / -6

This can be written as x = -4.

Consequently, x = -4 is the answer.

Step-by-step explanation:

Answer: 1, 20!

Step-by-step explanation:

= kx. where k is the constant of variation. Since k is constant (the same for every point), we can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = = 3.

Simply so, which graph represents an equation in the form y KX?

Slope of y = kx Theorem The graph of the direct-variation function with equation y = kx has constant slope k. Now solve this system of equations for k. So by the definition of slope, k is the slope of the line through these points. Thus, k is the slope of the line with equation y = kx.

Also, which statement is always true about the graph of an equation in the form y KX Y KX? The equation y = kx is a proportional graph. It means that you multiply x by a number and you have k. The point (0, 0) will always be on the graph, because no matter what K is, if you are multiplying by 0 for x, you will get 0 for y.

Secondly, what is Y KX called?

In the equation y = mx + b, if m is a nonzero constant and b = 0, then you have the function y = mx (often written y = kx), which is called a direct variation. In this function, m (or k) is called the constant of proportionality or the constant of variation.

What is direct variation?

Direct Variation. Directly Proportional. A relationship between two variables in which one is a constant multiple of the other. In particular, when one variable changes the other changes in proportion to the first. If b is directly proportional to a, the equation is of the form b = ka (where k is a constant).

For this first one it's:

A. ---x = 13

Step-by-step explanation:

The perpendicular bisector of a line divides the line into two equal segments and is perpendicular to the line

The perpendicular distance of point P from the line l is equal to the distance of the lost point s from the line l and points P and s are on opposite sides of the line l

The point s can be marked by constructing the perpendicular to line l passing through P

The steps to construct a perpendicular line from a point to a line and mark point s are given as follows;

The constructed point s above is the required point and points P and s are located on opposite sides of the line l

Answer:

D.

Step-by-step explanation:

The triangles are congruent, and the correct answer is D.

D. △JKL is congruent to △MNP because △JKL can be mapped to △MNP by a rotation of 180° about the origin followed by a translation 2 units up.

Rotation of triangle JKL by [tex]180^{o}[/tex] will result in the triangle with corresponding vertices of (2, 4), (3, 2) and (-1, 2).

so translating the resulting triangle two units up will result in the triangle with corresponding vertices (4, -2), (2, -3) and (2, 1) which is the same triangle like the given triangle MNP.

The figures is congruent because the 270° rotation about the origin or then the reflection over the x-axis would mapped ΔABC into ΔLMN.
