Answer 3

To solve the inequality -5x + 2 > 0, you can follow these steps:

Step 1: Simplify the equation -5x + 2 = 0 by isolating the variable x.

-5x + 2 = 0 Subtract 2 from both sides: -5x = -2 Now, to isolate x, divide both sides by -5: x = -2 / -5 x = 2/5

So, the solution for the equation -5x + 2 = 0 is x = 2/5.

Step 2: Determine the solution for the inequality -5x + 2 > 0.

Since we have already found the value of x to be 2/5, now we need to determine whether the inequality is true for x = 2/5 or any value of x greater than 2/5.

Plug in x = 2/5 into the inequality and see if it holds:

-5(2/5) + 2 > 0 -2 + 2 > 0 0 > 0

The inequality is not true for x = 2/5 since 0 is not greater than 0. It means that x = 2/5 is not part of the solution.

Step 3: Represent the solution on a number line.

Since x = 2/5 is not part of the solution, we can represent the solution on a number line by using an open circle at 2/5 to show that it is not included:

---o---o---------------------------- 0 2/5

Step 4: Determine the solution intervals.

The inequality -5x + 2 > 0 is true for all x values greater than 2/5 since the expression -5x + 2 is positive for those values.

Therefore, the solution interval is (2/5, ∞), which means all real numbers greater than 2/5 are solutions to the inequality.

In interval notation, the solution is (2/5, +∞).
