Five dimes and one quarter = .75.
9.75/.75=3.25*4/1=13
there are 13 "5 dimes and 1 quarter"s
so 65 dimes
50,000 answerrrrrrrrrrrrrrr
First find the slope using the two points (2,225) and (5,480)
(480-225)/(5-2) = 85
Then find b.
225 = 85*2 + b
225 = 170 + b
55 = b
y = 85x + 55 OR f(x) = 85x + 55 This is the answer to PART B.
Standard form PART A is 85x - y = 55
PART C Plot the y intercept, 55. From the y intercept count the slope 85 up right 1 and plot a point, draw a line through the points
The x axis is the number of days so it would be in intervals of 1.
The y axis is money, I would do intervals of $5
Answer: 4 weeks and 5 days
Step-by-step explanation:
9 weeks = 63 days
63 + 2 = 65
4 weeks = 28 days
28 + 4 = 32
65 - 32 = 33
7 * 4 = 28
33 - 28 = 5
28 days = 4 weeks
It sounds like you want to vertically compress an exponential growth function. If so, then the answer is (1/3)(3)^x, which is choice A.
This is because anything with (1/3)^x represents a decay function, allowing us to rule out C and D.
Choice B is a growth function, but comparing y = (3)^x to y = 3(3)^x, and we see there is a vertical stretch as opposed to a vertical compression going on. So we can rule out choice B as well. The only thing left is choice A.
