Is the equation 2x + 5 = 1 true, false, or open? Explain.

Answers

Answer:

open

Step-by-step explanation:

beacause

2x+5=1

2x=1-5

2x=-4

x=-4/2

x-2 so its open

An open statement is a statement that has an unknown variable

[tex]2x + 5 = 1[/tex] is an open statement

The equation is given as:

[tex]2x + 5 = 1[/tex]

From the equation, we have the following observations.

2, 5 and 1 are constants

x is a variable

Because the equation has a variable (i.e. x), then it is an open statement

Hence, [tex]2x + 5 = 1[/tex] is an open statement

What is the equation of the line written in slope-intercept from?

Answers

Answer:

Step-by-step explanation:

As we move along the graph from x = 2 to x = 3 (a change of 1), y decreases from y = 100 to y = 0 (a change of -100).  Thus, the slope of this line is

m = rise / run = -100/1 = -100.

The y-intercept is the point where the graph crosses the y-axis, and is (0, 200).

The equation of this line in slope-intercept form is  y = -100x + 200
