Marcie wants to enclose her yard with a fence. her yard is in the shape of a rectangle attached to a triangle. the formula for the area of the enclosed space is a = lw + 0.5bh. solve for b.

a. b = a divided by the quantity l times w plus 0.5 times h

b. b = the quantity a minus l times w all divided by 0.5 times h

c. b = a – lw – 0.5h

d. b = a + lw + 0.5h

no idea : o

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
