Properties of operations can be used to subtract expressions because <span>If you don't, you'll get the wrong answer, because you'll perform the solution steps in the wrong order. Also The Order of Operations provides us with a fixed approach to solving algebraic expressions. Without them, it would be impossible to get the same results because everyone would solve algebraic expressions in their own unique way. With the Order of Operations, everyone who solves a given problem will arrive at the same solution(s). This is what makes it possible to tackle problems like predicting the orbit path of Mars so we can land a probe on it...or develop software that does your math homework for you.;) </span>
Answer:
Here's one way to do it
Step-by-step explanation:
1. Solve the inequality for y
5x - y > -3
-y > -5x - 3
y < 5x + 3
2. Plot a few points for the "y =" line
I chose
You should get a graph like Fig 1.
3. Draw a straight line through the points
Make it a dashed line because the inequality is "<", to show that points on the line do not satisfy the inequality.
See Fig. 2.
4. Test a point to see if it satisfies the inequality
I like to use the origin,(0,0), for easy calculating.
y < 5x + 3
0 < 0 + 3
0 < 3. TRUE.
The condition is TRUE.
Shade the side of the line that contains the point (the bottom side).
And you're done (See Fig. 3).
