Rewrite the given parametric equations in Cartesian from x(t) = 2t– 1 y(t) = 5t
docker41 [41]

Hi there!

\large\boxed{(-\frac{5}{3},-\frac{5}{3})}

We can begin by setting the two expressions equal to solve for t:

2t - 1 = 5t

Subtract 2t from both sides:

-1 = 3t

Divide both sides by 3:

t = -1/3

Plug in this value of t into x(t) and y(t):

x(-1/3) = 2(-1/3) - 1 = -2/3 - 1 = -5/3

y(-1/3) = 5(-1/3) = -5/3

Thus:

(-5/3, -5/3) are the corresponding coordinates.

Given f (x)=2x-5x-3 and g (x)=2x^2+x what is (f/g)(x)<br>​
Rufina [12.5K]

ANSWER

( \frac{f}{g} )(x ) =   \frac{x - 3}{x}  \: where \:  \: x \ne0, -  \frac{1}{2}

EXPLANATION

Given:

f(x) = 2 {x}^{2}  - 5x - 3

and

g(x) = 2 {x}^{2}  + x

Then,

( \frac{f}{g} )(x ) =  \frac{f(x)}{g(x)}

Substitute the given functions;

( \frac{f}{g} )(x )  =  \frac{2 {x}^{2} - 5x - 3}{2 {x}^{2}  + x}

Factor

( \frac{f}{g} )(x ) =  \frac{2 {x}^{2} - 6x + x - 3 }{x(2x + 1)}

( \frac{f}{g} )(x ) =   \frac{2x(x - 3) +1 (x - 3)}{x(2x + 1)}

( \frac{f}{g} )(x ) =   \frac{(2x + 1)(x - 3) }{x(2x + 1)}

Cancel the common factors.

( \frac{f}{g} )(x ) =   \frac{x - 3}{x}  \: where \:  \: x \ne0, -  \frac{1}{2}
