Answrr is 2) {2,4,6,8}

It you be {2, 4, 6, 8} because they both include those number.

1=The non-intersection points of (B)
3=The non-intersection points of (A)
4=All of the points together dis-including doubles :)

Hope this helped :)

Multiply (-3a + 4b) by 5a.

Tasya [4]

Answer:

-15a^2+20ab

Step-by-step explanation:

Given data

We are given the expression

(-3a + 4b) to be multiplied by 5a

hence we have

(-3a + 4b)*5a

open bracket

-15a^2+20ab

Hence the answer is

-15a^2+20ab

If a boat with a value of $23, 000 depreciates at a rate of 18% per year, what is the value

Naily [24]

Using an exponential function, it is found that the value of the car after 5 years will be of $8,527.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

$A(t) = A(0)(1 - r)^t$

In which:

A(0) is the initial value.

r is the decay rate, as a decimal.

For this problem, the initial cost and the decay rate are given as follows:

A(0) = 23000, r = 0.18.

Hence the value of the boat after t years is given as follows:

$A(t) = A(0)(1 - r)^t$

$A(t) = 23000(1 - 0.18)^t$

$A(t) = 23000(0.82)^t$

The value after 5 years will be of:

$A(5) = 23000(0.82)^5 = 8527$

The value of the car after 5 years will be of $8,527.

First answer get best marks

Karo-lina-s [1.5K]

Answer:

The three expressions are the first option, the third option, and the forth option

Step-by-step explanation:

I don't really know how to explain my math lol but I solved 5(1/3x+7)-3(1/2x-), and got x, and plugged in x to the equation. I got my answer, and plugged in x to the rest of the equations and the first one, third one, and fourth ones were the ones that had equal answers. You may want to check my math though because i am not the best but that is what I got.

18. There are 56 fish in a tank, and each fish is yellow, blue, or black. There are six more yellow fish than blue fish, and fou

Alex73 [517]

Answer:

There are 24 yellow fish

Step-by-step explanation:

Blue: x

Yellow: x + 6

Black: x - 4

x + (x + 6) + (x - 4) = 56

3x + 2 = 56

3x = 54

x = 18

For each call to the following method, indicate what console output is produced:public void mysteryXY(int x, int y) { if (y == 1

soldi70 [24.7K]

Answer:

1. mysteryXY(4, 1); = 4

2. mysteryXY(4, 2); = 8, ,4

3. mysteryXY(8, 2); = 16, , 8

4. mysteryXY(4, 3); = 12, , 8

5. mysteryXY(3, 4); = 12, , 9

Step-by-step explanation:

public void mysteryXY(int x, int y) {

if (y == 1) {

System.out.print(x);

}

else

{

System.out.print(x * y + ", ");

mysteryXY(x, y - 1);

System.out.print(", " + x * y); }

}

mysteryXY(4, 1); = 4

On line 2, the value of Y is tested;

Y = 1. So the operation on line 3 will be executed.

The values of X will be printed

X= 1

For question 2 through 5, the value of Y is not 1, so it'll skip line and jump to 6.

The statement on line 6 print x * y appended with a comma

On line 7, the values of y is reduced by 1

On line 8, it prints , and the result of x * y.

So, we have

2. mysteryXY(4, 2); = 8, ,4

4 * 2 = 8

Reduce y by 1

Then, 4 * 1 = 4

Output: 8, , 4

Applying the same logic to 3 to 5

3. mysteryXY(8, 2); =

Output: 16, , 8

4. mysteryXY(4, 3); =

Output: 12, , 8

5. mysteryXY(3, 4); =

Output: 12, , 9
