Which of the following points is a solution to the system of equations x - y = 1 and -x + 3y = - 7?

kiruha [24]

Answer:

(-2,-3)

Step-by-step explanation:

Put the equations over each other.

$\binom{x - y = 1}{ - x + 3y = - 7 }$

Subtract the x values.

$\binom{ - y = 1}{3y = - 7}$

Subtract on both sides.

$2y = - 6$

Divide on both sides.

$y = - 3$

Insert the y value into one of the equations.

$x - ( - 3) = 1$

Get rid of the parenthesis.

$x + 3 = 1$

Subtract on both sides.

$x = - 2$

You could also individually plug in each solution into both equations to see if they are true.

Please help with the question.

Tju [1.3M]

Answer:

Step-by-step explanation:

Let y = f(x) and rearrange making x the subject

y = x² + 7 ( subtract 7 from both sides )

y - 7 = x² ( take the square root of both sides )

± $\sqrt{y-7}$ = x

Change y back into terms of x, thus

$f^{-1}$ (x) = ± $\sqrt{x-7}$
