Answers

Answer:

x = -5

Step-by-step explanation:

In both questions you want to get the x alone.

1.

-3x + (-6) = 9

First you want to add 6 to both sides so you'll be left with:

-3x = 15

Next, you want to divide both sides by -3 and you'll get:

x = -5

2.

-4x + (-12) = 8

You want to do the same thing as the first one so you'll add 12 to both sides:

-4x = 20

Then, you will divide both sides by -4 and get:

x = -5

The following table shows the values of y for different values of x:



x y

1 0


2 5




Which statement best explains whether the table represents a linear function or a nonlinear function?

It represents a linear function because its points are on a straight line.

It represents a linear function because its points are not on a straight line.

It represents a nonlinear function because its points are on a straight line.

It represents a nonlinear function because its points are not on a straight line.

Answers

Let's graph the points

Option A is correct

The true statement is It represents a linear function because its points are on a straight line.

What is Linear equation?

A linear function is a function that, when plotted, creates a straight line. Typically, it is a polynomial function with a maximum degree of 1 or 0. Nevertheless, calculus and linear algebra are also used to represent linear functions. The function notation is the only distinction. It is also important to understand an ordered pair expressed in function notation. When an is an independent variable on which the function depends, the expression f(a) is referred to as a function.

Given:

x y

0 -5

1 0

2 5

Now, the equation to represent the linear function is

y +5 = (0+5)/(1-0) (x- 0)

y+5 = 5x

y= 5x - 5

Now, plot the above equation on graph.

The graph represents the straight line.

Hence, It represents a linear function because its points are on a straight line.
