Which ordered pair is a solution of x-y=2 and
3y-x=8

The ordered pair is a solution of x - y = 2 and  3y - x = 8 is (x, y) = (7, 5)

Given two equations are:

x - y = 2 and 3y - x = 8

To find: orderes pair i.e (x, y)

Let us consider:

x - y = 2 eqn 1

3y - x = 8 eqn 2

Let us solve eqn 1 and eqn 2 to find values of "x" and "y"

On rearranging eqn 2, we get

-x + 3y = 8 eqn 3

Add eqn 1 and eqn 3

x - y = 2

-x + 3y = 8

(+)

0 + 2y = 10

2y = 10

Therefore from eqn 1,

x - y = 2

x - 5 = 2

x = 5 + 2 = 7

Thus the ordered pair to the given equations are (x, y) = (7, 5)

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

d. 8

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
