How do I tell whether the ordered pair is a solution of the given system ? {3x+y=4 and x-3y=-4

1 answer:

5 0

You plug the x and y values back into both equations. If both come out to be true statements ie. 4=4, 7=7 your answer is correct. If one or both of the equations turn into false statements, the ordered pair is not the solution to the system.

What is the value of x in 15x-10= 20

Brut [27]

15x-10=20
+10 +10
15x=30
\15 /15
x=2

you add 10 to both -10 (they cancek eachother out) and 20 (equals 30)
Then you divide 30 by 15 (equals 2) and 15 by 15 (they cancel eachother out)
Then you get x=2

F(x)=2x an$ g(x)=2x+3,what is the value of f(g(-8))

Fudgin [204]

First plug in g(x) into f(x)

F((g(x))=2(2x+3)

And now you plug in -8

F(g(-8))=2(-16+3)

F(g(-8))=2(-13)

F(g(-8))=-26
