Solve the inequality x-4 < - 3.Then graph the solution set.show your work.
bearhunter [10]

Answer:

x < 1

Step-by-step explanation:

x - 4 < - 3

<u>  + 4    +4</u>                        Do inverse operations by adding 4 on both sides

    x < 1

Therefore, the answer is x < 1.

(It isn't allowing me to attach a photo but I am just going to try make a visual of the graph below)

-4    -3    -2    -1     0    1     2    3      4

The circle is open because based on the concept that in inequalities, <em>less/greater than and/or equal to (such as these ≥ ≤ )</em> signs are graphed with closed circles, while less/greater than (like these > <) signs are graphed with open circles. The direction of the arrow is moving to the left on the number line because all possible values for x would be less than 1. When graphing the inequality you would use a solid line rather than a dashed line (I had to improvise since I could not attach an image).

Help Me Figure Out With This Question Please
adoni [48]

Answer:

Step-by-step explanation:

Since you know the angle is a right angle, you can say that the two equations equal 90. A right angle is 90 degrees

3x+40+4x-6=90

Then Simplify

7x+34=90

Then Subtract:

7x=56

Then Divide:

x= 8

After, plug x into the angle equations

1. 3(8)+40= 64

2.4(8)-6= 26

The angles are 64 and 26
