Determine which is the graph of the given function.

The answer is the fourth graph

Step-by-step explanation:

f(x) = 2x + 5 ⇒ x < 0

Represented by line its slope is 3 and its y-intercept 5

f(x) = 5 ⇒ 0 ≤ x ≤ 10

Represented by horizontal line at y = 5 from x = 0 to x = 10 with black circle on the point because x = 10

f(x) = 2x - 10 ⇒ x > 10

Represented by line its slope is 2 and start from y = 10 at x = 10 with empty circle on the point because x ≠ 10

1470

Step-by-step explanation:

4 + 3 = 7 + 7 = 14

105 × 14 = 1470

He ran 4 miles east and then 3 miles north. Since he burned calories using the diagonal line, he will burn calories from there as well. So, that's an extra 7 miles. To clarify, he burned a total of 1,470 calories on his run.
