Answer:

Step-by-step explanation:

x + y = 5 => x = 5 - y

y - 4 = - x

=> y - 4 = - ( 5 - y)

=> y - 4 = - 5 + y

=>4 = 5 , not true

So, no solution => system is inconsistent

How do I find the domain n range of this graph

motikmotik

Domain = {-3, 2}

Range = All real numbers

We can represent the range in interval notation as $(-\infty, \infty)$ which is basically saying $-\infty < y < \infty$ . The range is all real numbers due to the arrows meaning the graph extends up and down forever. So any y value is possible.

Notice with the domain we only have 2 valid x values -3 and 2. No other x values are allowed. Normally we use an interval of some kind to set up the domain, but we only have a set of values instead. The curly braces indicate "set".
