When something varies directly as something else, their ratio of change always stays the same.

56 / 7 = 8

Therefore,

8 * 3 = 24

If x = 3 then y = 24

Answer:

0

Step-by-step explanation:

Solution for cosx=-3/2 equation:

cos((3*pi)/5)*cos((3*pi)/20) = 0

(60*x^3)/(60*x^5) = 0

cos((3*pi)/5)*cos((3*pi)/20) = 0

cos((3*x)/5)*cos((3*x)/20) = 0

1.5/100 = 0

Write an explicit formula for the sequence 7, 2, –3, –8, –13, find the 14th term
Ilia_Sergeevich [38]

The 14th term is equal to -44.

y = 12 - 5x

The sequence can be represented by this function.

Each term is being subtracted by 5.

Using this function we can find the 14th time.


y = 12 - 5(14)

y = 12 - 56

y = -44
