Find the constant of variation k for the direct variation. x f ( x ) 0 0 3 6 4 8 7 14 a.) k = –2 b.) k = 0.5 c.) k = 2.5 d.) k = 2

The correct option is D.

Step-by-step explanation:

It is given that x is directly proportional to f(x) and constant of variation is k.

Therefore k is the slope.

Slope formula is

From the table the two points are (0,0) and (3,6).

Therefore the value of constant of variation is 2 and option D is correct.

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
