Answer:

(X , Y) = (3 , -2)

Step-by-step explanation:

Assuming this is solved via the comparison method ...

-5/3x+3 = 1/3x-3 which gets you x = 3

Now, substitute the given value of x into the equation, y=1/3x-3(-3)

Solve for Y, Y=-2

The possible solution of the system is the ordered pair (X , Y)

(3 , -2)

What is the inverse of the function f(x) = 2x + 1?

BaLLatris [955]

Answer:

$f^{-1} = \frac{x-1}{2}$

Step-by-step explanation:

$f(x) = 2x+1$

Replace it with y

$y = 2x+1$

Exchange the values of x and y

$x = 2y+1$

Solve for y

$x = 2y+1$

Subtracting 1 from both sides

$2y = x-1$

Dividing both sides by 2

$y = \frac{x-1}{2}$

Replace it by $f^{-1}$

So,

$f^{-1} = \frac{x-1}{2}$

(0.4y - 3)/(1.5y + 9) = -7/5

Jlenok [28]

Answer:

y = -3.84.

Step-by-step explanation:

(0.4y - 3)/(1.5y + 9) = -7/5

Cross multiply:

2y - 15 = -10.5y - 63

12.5y = -48

y = -3.84
