The x intercept is the value of x when y=0
the y intercept is the value of y when x=0
when y=0: 4x-0=24 => x=4
when x=0: 0-8y=24 => y=-3
so the x intercept is 4, and the y intercept is -3

4x-8y=24
move variables to the right side and change its sign
4x=24+8y
divide both sides by 4
x=6+2y

4x-8y=24
move variable to the right and change the sign
-8y=24-4x
divide both sides by -8
y=-3+1/2x

Determine whether the improper integral converges or diverges, and find the value of each that converges.

____ [38]

Answer:

$\int_{-\infty}^0 5 e^{60x} dx = \frac{1}{12}[e^0 -0]= \frac{1}{12}$

Step-by-step explanation:

Assuming this integral:

$\int_{-\infty}^0 5 e^{60x} dx$

We can do this as the first step:

$5 \int_{-\infty}^0 e^{60x} dx$

Now we can solve the integral and we got:

$5 \frac{e^{60x}}{60} \Big|_{-\infty}^0$

$\int_{-\infty}^0 5 e^{60x} dx = \frac{e^{60x}}{12}\Big|_{-\infty}^0 = \frac{1}{12} [e^{60*0} -e^{-\infty}]$

$\int_{-\infty}^0 5 e^{60x} dx = \frac{1}{12}[e^0 -0]= \frac{1}{12}$

So then we see that the integral on this case converges amd the values is 1/12 on this case.

There are 4,200 adults in Lakeview. Three-eighths of the adults in Lakeview do not have children. How many adults in Lakeview ha

Inessa [10]

To answer this, you first have to find 3/8 of 4200 by multiplying those two numbers.

$\frac{4200}{1} *\frac{3}{8}$

First, multiply the numerators.

4200x3=12600

Next, multiply the denominators.

1x8=8

You end up with $\frac{12600}{8}$ .

This fraction can be simplified to 1575.

All that's left is to subtract that number from 4200.

4200-1575=2625

The final answer is 2625 adults in Lakeview have children.
