The following set {x: x is a natural number, and a divisor of 9} in roaster form isa) { -1,-3.-9. 0 , 1,3, 9} b) { 9, 27, 81}c ) { 1,2,3} d) None of these

bull

step-by-step explanation:

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17

multiple all that

step-by-step explanation:

27×17

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
