Which property of equality justifies the following sequence of statements?

if 3x+2y=72

and 2y=3z ,

then 3x+3z=72

a. addition property
b. subtraction property
c. multiplication property
d. division property
e. none of the above

e. None of the above

Step-by-step explanation:

If

and

then     [By Substitution property]

is being substituted by

Since substitution property is not there in the choices, therefore 'none of the above' is correct.

1/2*qr*rs

step-by-step explanation:

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9
