3. Alonzo knows that in the following diagram points 4, B, C, and te wees. AB + BC = BC +CD. He correctly concludes that ABCD. Which of the following would
reason for this conclusion?
(1) a midpoint divides a segment into two
equal segments
(2) the whole is the sum of its parts
(3) the subtraction property of quality
(4) the addition property of quality

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.

the answer is a) a healthy economy because it results from a steady rise in demand.

step-by-step explanation:

i'm truly not sure if this is correct, but if you just want to simplify the equation, you would divide everything by two to get x + 6x= 16

if you want to solve-

7x=16

x= 16/7
