Okay, so this is basically telling you that there is no solution. You don't have to worry about there being one. You just have to justify (or explain) why there isn't one.

Basically, neither y or x is equal to anything. You couldn't make x equal to a value in y because x and y are both together in the equation and equal to numbers.

We can always move a factor to the other side. So,

x-2y= -8

Add 2y to the other side.

x= -8+2y

Now, plug in -8+2y as x.

3(-8+2y)- 6y=-12

-24+6y-6y= -12

The 6y's cancel out. So, we can't figure out what y is.

-24=-12 <- no y.

These two lines are parallel. They have direct proportion in each other. That is why there is no solution because the lines never cross. Parallel lines do not cross.

I hope this helps!

Answer:

z^ {8/5}

Step-by-step explanation:

$(z^{\frac{-4}{3})^{\frac{-6}{5} } \\We\ know\ that\ a^{(b)^c} = a^{bc}\\\\Hence, \\\\{z^{\frac{-4}{3})^{\frac{-6}{5}}\\}={z^{\frac{-4}{3}*\frac{-6}{5}\\}\\=z^{\frac{24}{15}}\\=z^\frac{8}{5}$

Two different airlines have a flight from Los Angeles to New York that departs each weekday morning at a certain time. Suppose t

marusya05 [52]

Answer: 0.8167

Step-by-step explanation:

Let E denotes the event that the first airline's flight is fully booked on a particular day, and F denotes the event that the second airline's flight is fully booked on that same day.

Given : P(E) = 0.7, P(F) = 0.6, and P(E ∩ F) = 0.49.

Then, by conditional probability formula , we have

$P(E|F)=\dfrac{P(\cap F)}{P(F)}\\\\=\dfrac{0.49}{0.6}=0.816666666667\approx0.8167$

Hence, the probability that the first airline's flight is fully booked given that the second airline's flight is fully booked.= 0.8167

Because it is a square all sides are equal so all sides are 20.25 because half of 81 is 40.5 and half of that is 20.25.
