The solution to an inequality is graphed on the number line.
a number line going from negative 5 to positive 5. a solid circle appears between positive 4 and positive 5. the number line is shaded from the circle to negative 5.
what is another way to represent this solution set?
a. {x | x < 4.5}
b. {x | x ≤ 4.5}
c. {x | x > 4.5}
d. {x | x ≥ 4.5}

Hey!

Open Dot - (< less than) or (> greater than)

Closed Dot - (≤ less than or equal to) or (≥ greater than or equal to)

Solution:

Then number-line shows a closed dot at 4.5. This shows that x is a number that is less than or equal to 4.5!

B. {x | x ≤ 4.5}

Hope This Helped! Good Luck!

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510
