Range is when you subtract the smallest number from the largest number. So X’s range would be 9-0 = 9 & Y’s range would be 8- -12 = 20 I believe.
Answer:
It has 0 distinct real number zeros. The function does not touch the x-axis
<u>Equation/Question:</u>
Sarah began the week with $2.60 in her lunch account. She deposited $20 on Monday, and then spent $4.75 each day that week for lunch. What was the balance in her lunch account at the end of the day on Friday?
<u>Answer/Way I did it:</u>
2.60+20.00 = 22.6
4.75 * 5 = 23.75 (There's obviously 5 school days)
22.60 - 23.75 = 1.15
(Simplify)

Answer:
Step-by-step explanation:
BC|| ED so <B=<D, <C=<E so the triangles are similar
the opposite sides of the equal angles are proportional
CD/AE=BD/AD=BC/DE
Ann wants to choose from two telephone plans. Plan A involves a fixed charge of $10 per month and call charges at $0.10 per minute. Plan B involves a fixed charge of $15 per month and call charges at $0.08 per minute.
Plan A $10 + .10/minute
Plan B $15 + .08/minute
If 250 minutes are used:
Plan A: $10+$25=$35
Plan B: $15+$20=$35
If 400 minutes are used:
Plan A: $10+$40=$50
Plan B: $15+$32=$47
B is the correct answer. How to test it:
Plan A: $10+(.10*249 minutes)
$10+$24.9=$34.9
Plan B: $15+(.08*249 minutes)
$15+$19.92=$34.92
Plan A < Plan B if less than 250 minutes are used.
