the region enclosed by 2y=5xy=5 and 2y+3x=8.

Decide whether to integrate with respect to x or y, and then find the area of the region.

The area is

you must have a typo in 2y=5xy=5

yeah its 2y=5x, y=5

To find the area of the region enclosed by the given equations, we need to determine which variable to integrate with respect to: x or y.

Let's start by looking at the given equations: 2y = 5xy = 5 and 2y + 3x = 8.

Looking at the equation 2y = 5xy = 5, we can see that there are two different expressions equal to 2y, which implies that the equation is written incorrectly. It seems like there might be a typo. Let's assume that the correct equation is 2y = 5.

Now, we have two equations: 2y = 5 and 2y + 3x = 8.

To decide whether to integrate with respect to x or y, we can graph the equations and observe the region they enclose.

Plotting the graph of 2y = 5 and 2y + 3x = 8, we find that both equations are lines. The equation 2y = 5 represents a horizontal line passing through y = 2.5 (or y = 5/2), while the equation 2y + 3x = 8 represents a line with a negative slope.

Next, we need to find the points where these lines intersect. By substituting y = 2.5 into the second equation, we get 2(2.5) + 3x = 8, which simplifies to 5 + 3x = 8. Solving for x, we find x = 1.

So, the lines intersect at the point (1, 2.5).

Now, we need to determine whether to integrate with respect to x or y. Since the region is defined by two vertical lines (the line passing through y = 2.5 is vertical) and one horizontal line (2y = 5), it makes sense to integrate with respect to y.

To find the limits of integration, we need to determine the y-values that enclose the region. From the graph, we can see that the region is enclosed between y = 2.5 and y = 5.

Now, we can proceed to find the area of the region by integrating with respect to y.

Integrating the equations 2y = 5 and 2y + 3x = 8 with respect to y, we get the following:

∫(2y = 5) dy and ∫(2y + 3x = 8) dy

The integral of 2y with respect to y is y^2, and the integral of 5 with respect to y is 5y.

The integral of 2y + 3x with respect to y involves treating x as a constant. So, we integrate 2y with respect to y to get y^2, and the constant term 3x remains unchanged.

Now, we can set up the definite integral to find the area:

Area = ∫[from y = 2.5 to y = 5] [(2y + 3x) - (2y = 5)] dy

Simplifying this, we get:

Area = ∫[from y = 2.5 to y = 5] (3x) dy

Since x is treated as a constant, we can move it outside the integral:

Area = 3x ∫[from y = 2.5 to y = 5] dy

Integrating with respect to y, we get:

Area = 3x [y] [from y = 2.5 to y = 5]

Substituting the limits of integration, we have:

Area = 3x [(5) - (2.5)]

Simplifying, we get:

Area = 3x (2.5)

Therefore, the area of the region enclosed by the given equations is 7.5x square units.
