Answer:
Step-by-step explanation:
<u>Given function</u>
<u>Its inverse is</u>
- x = (f^-1(x) - 3)/5
- 5x = f^-1(x) - 3
- f^-1(x) = 5x + 3
The second option is correct
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:
(x²-16x)
Step-by-step explanation:
thats all just multiply then
<h3>
Answer: Choice C) 11y+4 = 37</h3>
Explanation:
If we replaced y with 3 in choice A, then we get
2y-3 = 6
2(3)-3 = 6
6-3 = 6
3 = 6
which is a false statement. So choice A's solution is not y = 3. We can cross choice A off the list. The same applies with choices B and D as well.
Choice C is the answer because,
11y+4 = 37
11(3)+4 = 37
33+4 = 37
37 = 37
which is true. This confirms choice C.
Answer:
23/12
Step-by-step explanation:
2 1/2 = 5/2(3/3) = 15/6
1 1/3 = 4/3(2/2) = 8/6
15/6 - 8/6 = 7/6
7/6(1/2) = 7/12
16/12 + 7/12 = 23/12
