Since the slopes of the two lines are the not equal, they will have only one solution. The solution will be a point and can be found using the method given below.
We can find the solutions by simultaneously solving the two equations.
From first equation, the value of y comes out to be:

Using this value of y in second equation, we get:

Using this value of x, we can find y:
Therefore, there is only one solution to the given equations is which is (12, -9)
The full road trip is 50 miles.
Step-by-step explanation:
Given,
Distance traveled by Joe's family = 30 miles
This represents 60% of the total distance to be traveled.
Let,
x be the total distance.
60% of x = 30

Dividing both sides by 0.6

The full road trip is 50 miles.

The answer is A.
The population doubles every year, so that means we multiply the original population of 150 by 2 each year.
The probability of multiple events happening is found by multiplying the probabilities of each event together.

So yes, 1/10 is the answer :)
