Answer:

8 cups of shampoo concentrate.

Step-by-step explanation:

Set up a proportion and solve for x.

$\frac{Shampoo}{Water}\\\\\frac{2}{9}=\frac{x}{36}\\\\36(\frac{2}{9})=36(\frac{x}{36})\\\\8=x$

its 8

Step-by-step explanation:

use ratio solution ..

2 shampoo : 9 water

8 shampoo : 36 water

9x4 = 36

same goes too shampoo.. it needs to be multiplied with 4 as to get 36 water u multiplied 9 with 4

Answer:

(a) $8 x(5 x-6)=40 x^{2}-48 x$

Step-by-step explanation:

(a) To find verify the answer we need to multiplying the equation $8 x(5 x-6)$

$8 x(5 x-6)=40 x^{2}-48 x$

Thus, this statement is true.

(b) To find verify the answer we need to multiplying the equation $-4 x\left(2 x^{2}+1\right)$

$-4 x\left(2 x^{2}+1\right)=-8 x^{3}-4 x$

Hence, the given statement is false.

$\begin{aligned}(x-3)(5 x-6) &=5 x^{2}-6 x-15 x+18 \\&=5 x^{2}-21 x+18\end{aligned}$

Hence, the given statement is true.

(d) To find verify the answer we need to multiplying the equation $(2 x+3)\left(x^{2}+3 x-5\right)$

$\begin{aligned}=(2 x+3)\left(x^{2}+3 x-5\right) &=2 x^{3}+6 x^{2}-10 x+3 x^{2}+9 x-15 \\&=2 x^{3}+9 x^{2}-x-15\end{aligned}$

Hence, the given statement is false.

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
