Answer:

Smaller number = 12

Larger number = 24

Step-by-step explanation:

Let's call X the smallest number, while Y is the largest number.

In this case, Y = 2X

The equation that represents the given case is,

X + Y = 36

But being Y = 2X we substitute in the equation, obtaining ...

X + 2X = 36

Now we add the X ...

3X = 36

We isolate the X to know its value ...

$x=\frac{36}{3}$

X = 12

Now we calculate the value of Y ...

Y = 2X

Y = 2 (12)

Y = 24

Smaller number = 12

Larger number = 24

Both conditions are met:

(1) The largest number is twice the smallest number: 12 * 2 = 24

(2) The sum of the two numbers is 36: 12 + 24 = 36

Hope this helps!

12 and 24
The equation is 2x + x =36
So 3x = 36
Then divide each side by 3
So x =12
That is the smaller number
Multiply it by 2 to get the bigger number since it's twice the number

Find the average rate of change over the interval [-1,2] (from x = -1 to x = 2) for the graph below

Lyrx [107]

Hello!

Find the coordinate where x = -1:

At x = -1, y = 1, so the coordinate is (-1, 1).

Find the coordinate where x = 2:

At x = 2, y = -2, so the coordinate is (2, -2).

Find the rate of change between the points using the slope formula:

$slope = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Plug in the coordinates above:

$slope = \frac{-2-1}{2-(-1)}$

Simplify:

$slope = \frac{-3}{3} = -1$

Thus, the rate of change between the points is -1.

What is the value of (7 + 2i)(3 - i)?

Harrizon [31]

There are two ways to work this out: normal variables or using "imaginary" numbers.

Normal variables:
$(7+2i)(3-i)\\(7*3)+[7*(-i)]+(3*2i)+[2i*(-i)]\\21-7i+6i-2i^{2}\\\\21-i-2i^{2}$

Imaginary numbers:
Using the result from earlier:
$21-i-2i^{2}$
Now since $i = \sqrt{-1}$ , then the expression becomes:
$21-i-2i^{2}\\21-i-2(\sqrt{-1})^{2}\\21-i+(-2)(-1)\\21-i+2\\\\23-i$
