Answer: The slope is 2
Step-by-step explanation: For questions like these, find 2 points on the graph that are on whole numbers, for example (10,60) and (20,80). Then use the formula y2-y1/x2-x1 to solve for the slope, which would be the same thing as rate of change. 80-60/20-10 which equals 2. The slope would be 2.
Hello!
First, you'll need to multiply 1.33 by 15, since the value of the card increases by $1.33 every year. After you've multiplied, you'll get $19.95. NExt you'll need to add 8.95 to 19.95 to get the value of the card after 15 years. After, you should get a value of $28.90 for the card.
So yes, having the hope of making at least $26 off the card IS a viable option.
I hope this helps!

Answer:
Below in bold.
Step-by-step explanation:
Total number of marbles = 3+4+5 = 12
P(white, red) = 4/12 * 3/11
= 12/132
= 1/11,
P(blue, white, red) = 5/12 * 4/11* 3/10
= 60/1320
= 6/132
= 1/22.
