<span>The table shows the outputs, y, for different inputs, x:
Input (x) 1 3 5 7
Output (y) 8 6 5 4
Part A: Do the data in this table represent a function? Justify your answer. (3 points)
Yes, the data in the table represent a function. The reason is that given an input (value of x), in the domain of the function (which is 1, 3, 5, 7), you can state the correspondent output (value of y) without ambiguity.
Part B: Compare the data in the table with the relation f(x) = 4x + 8. Which relation has a greater value when x = 3? (2 points)
x = 3 => f(3) = 4(3) + 8 = 12 + 8 = 20
While the image of 3 in the data is y = 6.
So, the function f(x) = 4x + 8 has a greater value when x = 3.
Part C: Using the relation in Part B, what is the value of x if f(x) = 76? Be sure to show all your work.
f(x) = 76 = 4x + 8 => 4x = 76 - 8 = 68
=> x = 68/4 = 17</span>
Answer
5 to the power of 7
Explanation
Multiply the length by the width. When multiplying numbers with exponents and similar bases, you can just add the exponents. If this doesn't make sense I'll show you.
The length is 5*5*5*5.
The width is 5*5*5.
Multiply this, and you get 5*5*5*5*5*5*5.
This is 5 times itself seven times.
The area of the rectangle is 5 to the power of 7.
The rule is add 18 each time and the mistake is 55
Answer:1. 5/6
2. 7/10
3. 11/12
4. 7/10
5. 13/15
6. 19/20
7. 5/8
8. 7/9
9. 5/12
10. 5/12
11. 11/12
12. 9/14
Step-by-step explanation:
multiply each to make common denominators and then add the numerators together. simplify if needed.

Answer: Income is left each week after those deductions = $ 388.216
Explanation:
Amount Seth earns per week = $ 560
So, income is left each week after those deductions is given by
Hence , Income is left each week after those deductions = $ 388.216
