How do you complete each ordered pair (_, -10) so that it is a solution to 6x - y = 7?

Answer 1

Ethan Adkins

See the entire solution process below:

7 - 10# = #6x + color(red)(10) - 10

#6x plus 0 equals -3#

#6x equals -3#

Color(red)(6) - 3 #(6x)/color(red)(6)

Cancel(color(black)(6)) #(color(red)(x)/cancel(color(red)(6)) = -1/2#

#x equals -1/2#

The pair that is ordered is #(-1/2, -10)#.

To complete each ordered pair so that it is a solution to ( 6x - y = 7 ), substitute -10 for y in the equation and solve for x:

( 6x - (-10) = 7 )

( 6x + 10 = 7 )

( 6x = -3 )

( x = -\frac{1}{2} )

So, each ordered pair would be (-1/2, -10).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
