Write an equation that relates the number of tennis balls (y), with the number of cans (x). (Do not put spaces between numbers, variables, and operations)

y = 3x

Step-by-step explanation:

Since, line given in the graph passes through origin (0, 0), relation between the number of tennis balls (y) and the number of cans (x) will be proportional.

y ∝ x

y = kx

Here 'k' = proportionality constant

Since the given line is passing through (1, 3),

3 = k(1)

k = 3

Therefore, equation of the line will be,

y = 3x

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✌✌✌
