This is a system of equations. The best way to solve it is by realizing that you have two equations equal to y. Since y = y, it follows that $-x+7=x-1$ . Solving for x, you get 4.

$7=2x-1 \\ 8=2x \\ 4=x$

Then, substitute 4 into one of the original equations to find y.

$y=(4)-1=3$ .

The solution is $(4,3)$ . I have attached a graphical representation of the solution as well.

Which relation below represents a one to one function

Scilla [17]

Answer:

<h2>Second table</h2>

Step-by-step explanation:

<em>One-to-one function is a function that preserves distinctness: it never maps distinct elements of its domain to the same element of its codomain. Every element of the function's domain is the image of at most one element of its domain.</em>

First table:

No. Because for x = 7.25 and x = 8.5 we have the same value of y = 11

Second table:

Yes. Because for all values of x we have different values of y.

Alright, lets get started.

The base price is given : $ 24990

The dealer pays 76% of the base price means

he pays for base price : $24990 * \frac{76}{100}$
