Let x = number of students in each of the remaining rows
266 = (10 x 20) + (5 x 8) + 2x
266 - (10 x 20) - (5 x 8) = 2x
266 - 200 - 40 = 2x
26 = 2x
x = 26/2
x = 13
Answer: B. g(x)=3x-2-7
Hope this helps someone in the future. :D
The direct variation between x and y may be written as,
y = kx
where k is the constant of variation. From the first set of values of the variables,
12 = k(8)
the value of k is 1.5. Substituting the next set to the same equation,
y = 1.5(14)
The value of y is 21.
The tangent meets the radius at a right angle.
We use (the converse of) the Pythagorean Theorem to check:

Not a right triangle
Answer: FALSE
Answer:
No
Step-by-step explanation:
No function, because the same output can't have two different inputs.
