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

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
