Simply the rational expression.state any restrictions on the variable. k2-k-2/k2-4k-5

hjlf

We are given

$\frac{k^2-k-2}{k^2-4k-5}$

Firstly, we will factor numerator and denominator

$\frac{k^2-k-2}{k^2-4k-5}=\frac{(k-2)(k+1)}{(k-5)(k+1)}$

Restrictions:

we know that denominator can not be zero

so, we can set denominator =0

and solve for k to get restrictions

$(k-5)(k+1)=0$

$k=-1,k=5$

Simplification:

$\frac{k^2-k-2}{k^2-4k-5}=\frac{(k-2)(k+1)}{(k-5)(k+1)}$

we can see that k+1 gets cancelled

so, we get

$\frac{k^2-k-2}{k^2-4k-5}=\frac{(k-2)}{(k-5)}$ ..........Answer

F(x) = 3x + 2 replace f(x) with y

kirill [66]

Answer:

-1 x - 2

f (x) = -----------

Step-by-step explanation:

Then we have y = 3x + 2.

Next, interchange x and y, obtaining x = 3y + 2

Next, solve this result for y: 3y = x - 2; then divide both sides by 3:

y = (x-2)/3

Last, replace "y" with the inverse function label:

-1 x - 2

f (x) = -----------

Determine which equations below, when combined with the equation 3x-4y=2, will form a system with no solutions. Choose all that

svetoff [14.1K]

Two equations will not have solution if they are parallel and have different y-intercepts. Parallel lines have the same slope. In a slope-intercept form, the equation of the line can be expressed as,

y = mx + b

where m is slope and b is the y-intercept.

Given: 3x - 4y = 2
Slope-intercept: y = 3x/4 - 1/2

A. 2y = 1.5x - 2
Slope-intercept: y = 3x/4 - 1

B. 2y = 1.5x - 1
Slope-intercept: y = 3x/4 - 1/2

C. 3x + 4y = 2
Slope-intercept: y = -3x/4 + 1/2

D. -4y + 3x = -2
Slope-intercept: y = 3x/4 + 1/2

Hence, the answers to this item are A and D.
