How do you solve and graph this equation

Step-by-step explanation:

<, > - dotted line

≤, ≥ - solid line

<, ≤ - shaded region below a line or to the left if is a vertical line

>, ≥ - shaded region above a line or to the right if is a vertical line

----------------------------------------------------------

We have x ≥ 4:

solid vertical line x = 4

shaded region to the right

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✌✌✌
