pls provide full explanation !! Given that a varies inversely as (b + 2) and that the sum of the values of a when b = -1 and when b = 2 is 60 , find the value of a when b = -5. (b) Given that 5 men can pave a stretch of road of length 200 m in 4 hours, how long will it take 8 men pave a 500 m stretch of road?​

b. x + 1

step-by-step explanation:

i'am smart

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
