Answer:

-30

Step-by-step explanation:

To find slope, subtract two y's and then subtract the x's in the same order.

12-(-18)=30=-30

11-12 -1

You could also switch the order like this...

-18-12=-30=-30

12-11 1

As you can see, both of the ways of solving for slope resulted in -30.

Hope this helps!! Have a great day :3

The ellipse with x-intercepts (2, 0) and (-2, 0); y-intercepts (0, 4) and (0, -4).

masya89 [10]

Answer:

$\dfrac{x^2}{4}+\dfrac{y^2}{16}=1$

Step-by-step explanation:

If the ellipse has its x-intercepts at points (2, 0) and (-2, 0) and y-intercepts at points (0, 4) and (0, -4), then its symmetric across the y-axis and across the x-axis.

Moreover,

$a=2\\ \\b=4$

The equation of such ellipse is

$\dfrac{x^2}{a^2}+\dfrac{y^2}{b^2}=1$

Hence, the equation of the ellipse is

$\dfrac{x^2}{2^2}+\dfrac{y^2}{4^2}=1\\ \\ \\\dfrac{x^2}{4}+\dfrac{y^2}{16}=1$

A principal of $3500 is invested at 3.75% interest, compounded annually. How much will the investment be worth after 12 years? R

Thepotemich [5.8K]

Use the compound amount formula:

A = P*(1+r/n)^(nt)

Here,

A = $3500*(1+0.0375/12)^(12*12) = $5485.24
