Simplify the rational expression. State any restrictions on the variable.

AveGali [126]

Answer:

The last choice.

Step-by-step explanation:

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

The value of k must be restricted from being one that makes the original denominator zero. Hence k ≠ -1 or 5.

Okay so this problem basically is saying if the value is 90000 and per every 1000 she has to pay 31$ in tax

So first divide $90,000 by $1,000 you should get 90
Now you can do 90 times $31 to find how much tax she will have to pay which equals $2,790 tax total

The table below represents the distance of a car from its destination as a function of time.

KIM [24]

We are given the table that projects the distance of the car per hour. x is associated to time while y is associated to distance. The equation of the line after plotting in MS Excel is y = 900 - 50x. Hence the y-intercept is equal to 900 while the slope is equal to -50. The domain of the function that is x is all positive numbers.

Find the area giving brainlieas

Lelu [443]

Answer: 6.5 in

Step-by-step explanation:

Given the information we have, we first need to turn this into a parallelogram. So, now that we have a parallelogram, we need to find the area of that and divide it by two. So 3 1/4 x 4 = 13

So now that we have the area of the square, we need to divide it by two. $\frac{13}{2} = 6.5$ .

So our answer is <u>6.5 in</u>
