To solve a problem like this, we can setup a basic algebraic equation.

52+14=x
66=x

We know this equation is true because 14 years ago, she was 52 so 14 years later, she is 66.

The first term of a sequence is a multiple of 3 The second term of this sequence is 6 less than the first term. The third term i
Mekhanik [1.2K]

Answer:

First term = 15

Second term = 9

Third term =  3

Step-by-step explanation:

Given,

First term = 3x

Second term = 3x - 6

Third term =  \frac{1}{5} (3x) =  \frac{3x}{5}

Also,

3x -  \frac{3x}{5}  = 12

\frac{15x}{5}  -  \frac{3x}{5}  = 12

\frac{15x - 3x}{5}  = 12

15x - 3x = 12 \times 5

12x = 60

x =  \frac{60}{12}

x = 5

With the value of x, we conclude that the first three terms are as follows:

First term = 3x = 3×5 = 15

Second term = 3x - 6 = 15 - 6 = 9

Third term = \frac{3x}{5} =\frac{15}{5}= 3

Find dy/dx by implicit differentiation for x + 2y = xy.
Stella [2.4K]
Ok to find dy/dx of x+2y=xy we take derivative of both sides with respect to x

1+2dy/dx = x*dy/dx +y*dx/dx
1+ 2dy/dx = x*dy/dx + y* 1
2dy/dx +1 = x*dy/dx + y

2y’ + 1 = xy’ + y

2y’ + 1 - xy’ = y

2y’ -xy’ = y - 1

y’(2-x) = y - 1

so we get finally

y’= (y-1)/(2-x)

Hope this helps you understand the concept! Any questions please ask! Thank you so much!!
