Which statement best applies to the slope of the line below?
a the slope is negative
b. the slope is zero
c. the slope is positive
d. the line has no slope

B. the slope is zero

Step-by-step explanation:

The line shown is a horizontal line.  Horizontal lines have zero slope.

Vertical (up and down) lines do not have a slope ( or what we usually call undefined slope)

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
