I'm giving Brainliest to CORRECT answers. (IF I GET AN UNKNOWN LINK I WILL DESTROY YOU) a. List all the factors of 42. b. What is the greatest common factor of 42 and 15? c. What is the greatest common factor of 42 and 50?

Step-by-step explanation:

a) 1,2,3,6,7,14,21,42

b)3

c)2

A) 1, 2, 3, 6, 7, 14, 21, 42

B) 3

C) 2

Step-by-step explanation:

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
