Solve the system with elimination 4x+3y=1 -3x-6y=3

Mathematics
1 answer:
Nuetrik [128]4 years ago
5 0

Answer:

x = 1, y = -1

Step-by-step explanation:

If we have the two equations:

4x+3y=1 and -3x - 6y = 3, we can look at which variable will be easiest to eliminate.

y looks like it might be easy to get rid of, we just have to multiply 4x+3y=1  by 2 and y is gone (as -6y + 6y = 0).

So let's multiply the equation 4x+3y=1  by 2.

2(4x + 3y = 1)\\8x + 6y = 2

Now we can add these equations

8x + 6y = 2\\-3x-6y=3\\

------------------------

5x = 5

Dividing both sides by 5, we get x = 1.

Now we can substitute x into an equation to find y.

4(1) + 3y = 1\\4 + 3y = 1\\3y = -3\\y = -1

Hope this helped!

The probability that Fred's bus is late on any day is 0.09.
miv72 [106K]

Answer:

The bus would be 36 times late in 400 times of when Fred takes the bus

Step-by-step explanation:

Given that the probability of being the bus late is 0.09.

In order to find the number of times the bus will be late will be calculated by multiplying the total number of observations by probability.

It is also given that the total number of days he waits for bus is 400 times.

So,

The bus will be:

= 0.09*400\\=36

Hence,

The bus would be 36 times late in 400 times of when Fred takes the bus
