Is the point (1, -3) a solution to the system? Show all work

The point P(1,-3) is not a solution to the system.

Step-by-step explanation:

Given    

Let a point be P(1,-3)

Here x = 1 ; y = -3

Substituting the values of x,y in the function

For y<x-1

-3 < 1-1

-3<0 (True)

now for,

y>-x+2

-3 > -1 + 2

-3 > 1 (False)

Hence the point is not a solution to the system.

y=mx+b

step-by-step explanation:

m slope

b y-intercept

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
