In an inverse variation, y = 4 when x = 25. Write an inverse variation equation that shows the relationship between x and y.
Write the equation using a decimal or an integer.

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18

i think it is 18

step-by-step explanation:

positive

step-by-step explanation:

the quadrant is facing upwards

if you was gonna solve for a, a is a   < -12
