Figure abcde was reflected across the line y = x to
create figure a'b'c'd'e'. what are the coordinates of
the pre-image of e?

See below.

Step-by-step explanation:

If the coordinates of E' were (a, b) the coordinates of  the pre-image E would be (b, a).

y = x  is the line so the coordinates will flip.

It would be -2, 6

Step-by-step explanation:

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
