name the property of equality or congruence that justifies going from the first statement to the second statement.
st=qr
qr=st
a) reflexive property of congruence
b) symmetric property of congruence
c) transitive property of congruence
d) substitution property of congruence

b.Symmetric property of congruence.

Step-by-step explanation:

We are given that

ST=QR

QR=ST

We have to find the name of the property of equality or congruence that justifies going from the firs statement to the second statement.

When AB=CD

CD=AB

It is called symmetric  property of congruence.

Therefore, given property is symmetric  property of equality that justifies going form the first statement to the second statement.

b.Symmetric property of congruence.

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,

answer4 to the second power is 16

and 4 to the third power is 64,
