Is the function y = 3x + 7 a proportional relationship? if it is, what is the slope of the line? a. this is a proportional relationship. the slope is 3 7 . b. this is a proportional relationship the slope is 7 3 . c. this is a proportional relationship. the slope is 3. d. this is not a proportional relationship.

D. This is NOT a proportional relationship

Any equation with a '+b(7 in this case)' or y-intercept otherthan (0,0) is not proportional.

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✌✌✌

step-by-step explanation:

we have

using a graphing tool

see the attached figure

this is a quadratic equation (vertical parabola) open up

the vertex is a > vertex

the domain of the function is all real > interval (-∞,∞)

the range of the function is the > [-6.125,∞)

the function has two x->   and

the function is increasing over the > (0.25,∞)

the function is decreasing over the > (-∞,0.25)
