A. X + 2y = 8 x = -5
b. 3x = 8
3x + y = 15
c. y= -7x + 13
y =-1
d. y =2x - 7
4+ y = 12

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.

i think asking google will you get the answer to that question

well your weight will go up if you are not going to burn the calories/ carbs

step-by-step explanation:

answer: i believe it is c
