Decide whether 0 is a solution of the inequality: a.) 2x – 1 9 c.) x – 3 > 1

Mathematics
1 answer:
marin [14]3 years ago
5 0

Step-by-step explanation:

How to check a solution: Just as you can check the solution to an equation, you can check a solution to an inequality. First, you check the end point by substituting it in the related equation. Then you check to see if the inequality is correct by substituting any other solution to see if it is one of the solutions.

How to tell if its true or false: An inequality is a statement that shows the relationship between two (or more) expressions with one of the following five signs: <, ≤, >, ≥, ≠. Like an equation, an inequality can be true or false. 34 - 12 > 5 + 2 is a true statement. 1 + 3 < 6 - 2 is a false statement.

5x+4.27xy+20y+36y-19x+9.11
mote1985 [20]
So what I did was the terms that were alike like this: (5x -19x)+(20y+36y)+4.27xy+9.11. Then I simplified and got -14x+56y+4.27xy+9.11. The terms 4.27xy and 9.11 were not in ()'s because they were the only ones with an alike term. Hope that helps and also try to doing the steps and see what you get. If you get it wrong look to see where you messed up and try again! If I am wrong please notify me, I would appreciate it!

What is y+1=2(x-4) written in standard form
IrinaVladis [17]

Answer:

2x - y = 9

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

Rearrange y + 1 = 2(x - 4) into this form

y + 1 = 2x - 8 ( add 8 to both sides )

y + 9 = 2x ( subtract y from both sides )

9 = 2x - y ⇒ 2x - y = 9 ← in standard form
