Answer 1

System of Inequalities

To solve the system of inequalities {2x + 3 > x + 4x - x < 3}, we need to solve each inequality separately and then find the intersection of their solution sets.

Let's start with the first inequality: 2x + 3 > x + 4x - x.

Simplifying the inequality, we have:

2x + 3 > 4x

Subtracting 2x from both sides, we get:

3 > 2x

Dividing both sides by 2, we have:

3/2 > x

So the solution to the first inequality is x < 3/2.

Now let's move on to the second inequality: x < 3.

The solution to this inequality is x < 3.

To find the intersection of the solution sets, we need to find the values of x that satisfy both inequalities. In this case, the values of x that satisfy both inequalities are x < 3/2 and x < 3.

Therefore, the solution to the system of inequalities is x < 3/2.

Additional Questions

1. Solve the inequality 4x > 5x - 7.

To solve the inequality 4x > 5x - 7, we need to isolate x on one side of the inequality sign.

Subtracting 5x from both sides, we get:

-4x > -7

Dividing both sides by -4 (remember to reverse the inequality sign when dividing by a negative number), we have:

x < 7/4

Therefore, the solution to the inequality 4x > 5x - 7 is x < 7/4.

2. Find the inverse function of y = 3x - 5.

To find the inverse function of y = 3x - 5, we need to swap the x and y variables and solve for y.

Let's start by swapping the variables:

x = 3y - 5

Now, let's solve for y:

x + 5 = 3y

Dividing both sides by 3, we get:

y = (x + 5)/3

Therefore, the inverse function of y = 3x - 5 is y = (x + 5)/3.
