X+x+(x-45)+(x-45)+(x-45)=540 and they're all degrees

1 answer:

6 0

x + x + (x-45) + (x-45) + (x-45) = 540

x + x + x + x + x - 45 - 45 - 45 = 540

5x - 135 = 540

5x = 540 + 135

5x = 675

x = 675/5

x = 135

x = 135°

Use the graph to determine the domain and range of the relation, and whether the relation is a function.

Westkost [7]

Answer:

Step-by-step explanation:

We can use vertical line test to determine if a relation is a function.

If a vertical line passes the graph at any point only once, then the relation is a function, if there is even 1 line that passes the graph at 2 points, then it is NOT a function.

The domain is the set of allowed x-values of the function. The range is the set of allowed y-values of the function.

Looking at the graph, we see that there are a lot of vertical lines that cuts the graph two times. Suppose x=3, x=4, x= 5 etc. So it is not a function.
As for domain, we see that curve swings from x = -8 to x = 8, so the domain is from -8 to 8.
As for range, we that the curve stretches all the way from negative infinity to positive infinity, so the range is the set of all real numbers.
