Answer:

y=24

Step-by-step explanation:

<u>Given:</u>

y=kx

<u>Substitute:</u>

\left \{ {{y=12} \atop {x=2}} \right. into y=kx

12=k\times2

<u>Swap the sides:</u>

<u />k\times2=12

<u>Divide both sides of the equation by the coefficient of variable:</u>

<u />k=\frac{12}{2}

<u>Cross out the common factor:</u>

<u />k=6

<u>Find the equation of the function:</u>

<u />y=6x

<u>Substitute:</u>

<u />y=6\times4

<u>Calculate the product or quotient:</u>

<u />y=24

There are 100 people in a wedding house, including children, men and women, and there are 100 pappadas to give with Sadya Te.
olga nikolaevna [1]

Answer:

Two possible sets of answers.

5 men, 11 women and 42 children, or

10 men, 2 women and 88 children

Selamat Sadhya!

Step-by-step explanation:

M = number of men

W = number of women

100-M-W = number of children

Total number of pappadas

5M+3W+(100-M-W)/2 = 100

Solve for W

W = (100-9M)/5 .......................(1)

Examine equation (1).

In order to have W as a whole number, M must be multiple of 5

Therefore M = 5 or 10

If M = 5, W = (100-45)/5 = 11 and children = 100-5-11 =  84

If M = 10, W = (100-90)/5 = 2 and children = 100-10-2 = 88

Simplify x0 y-3/x2 y-1
Natali5045456 [20]

Answer:

x^0 y^-3 / x^2 y^-1  

= 1 /  x^2 y^-1 (y^3)  ...because  x^0 = 1 and  [(y^-1) (y^3)] = y^2

= 1/(x^2 y^2)

Help me please help me thank you
kow [346]

Answer: 110, 35, 70, G, J, F, E, B, A, H, C, D, I

Step-by-step explanation:

8. For number 8, you will be using the exterior angle theorem. The exterior angle theorem states that the exterior angle equals the two angles inside the given triangle. Since we have 50 and 60, you will add 50 + 60 to get 110.

9. In this problem, you shall use the vertical angle theorem. The vertical angle theorem is simply that any angles vertical from one another are congruent. So a will be also 35 degrees.

10. This is an image depicting two lines cut by a transversal, creating multiple congruent angles. With this, you will be using the alternate interior angle theorem. Alternate interior angles are angles on different sides of the transversal but inside both of the lines that were cut into, as shown above. So,  b will also equal 70 degrees.

Part B:

1. G

2. J

3. F

4. E

5. B

6. A

7. H

8. C

9. D

10. I
