Math Problem Statement

determine if (2,10) is a solution for the inequality y>5x−2 ? Be sure to state if (2,10) is a solution or not.

Solution

We are tasked with determining if the point (2,10)(2, 10) is a solution to the inequality y>5x2y > 5x - 2.

Step 1: Substitute x=2x = 2 and y=10y = 10 into the inequality.

The inequality is y>5x2y > 5x - 2.

Substitute x=2x = 2 and y=10y = 10 into the inequality:

10>5(2)210 > 5(2) - 2

Step 2: Simplify the right-hand side.

10>10210 > 10 - 2 10>810 > 8

Step 3: Check if the inequality holds true.

Since 10>810 > 8 is true, the point (2,10)(2, 10) satisfies the inequality.

Conclusion:

Yes, (2,10)(2, 10) is a solution to the inequality y>5x2y > 5x - 2.


If you would like further clarification or details, feel free to ask!

Here are five related questions you may find interesting:

  1. How do you graph the inequality y>5x2y > 5x - 2?
  2. How would the solution change if the inequality were y5x2y \geq 5x - 2?
  3. What happens if the point is on the boundary line y=5x2y = 5x - 2?
  4. How do you test a point for inequalities with "less than" instead of "greater than"?
  5. What is the significance of the slope and y-intercept in graphing inequalities?

Tip: When solving inequalities, always test points carefully by substitution to verify whether they satisfy the inequality!
