Answer:
We make the table of these values at different values of x.
x A B C D
2 66.66 49.3 52.5 50
4 94.57 71.44 106.3 104
6 134.14 103.57 160.1 158
8 190.27 150.14 213.9 212
10 269.91 217.64 267.7 266
12 382.85 315.5 321.5 320.
Hence, the function that best represents the data is:
Option C.
y=26.9x-1.3
Step-by-step explanation:
390, because 10% of 1300 is 130 so 130 times 3 = 390
B


b=

Where k is a constant of proportionality.
b=18, c=4,d=9, e=6
Finding the value f k,
18=

6k=18
k=3
The equation then is;
b=

The constant of variation=3
The answer is 7, 2(7x5) + 2(4x7) + 2(5x4) = 166
Answer:
y=3x - Linear Function
y=4x-1 - Linear Function
y=x²+1 - Non-Linear Function
y=0.75x+2 - Linear Function
y=0.5x³ - Non-Linear Function
(For a function to be linear, both x & y must equal 1.)
