There are 5280 ft in a mile. 55*5280=290400. So the car is travelling 290,400 ft/hour
We have been given a system of equations.
and
. We are asked to find the solution of our given system of equations.
The solution of our given system of equations will be the point, where both lines will intersect.
To find intersection point, we will equate both equations as:





Now we will substitute
in equation
and solve for y.

Therefore, the point
is the solution of our given system of equations.
We can verify our answer by graphing both equations.
= (1 - tan^2 (x)) / (1 + tan^2 (x))
= (1 - (-4/3)^2) / (1 + (-4/3)^2)
= (1 - (16/9)) / (1 + (16/9))
= (9 - 16) / (9 + 16) [By multiplying numerator and denominator with 9]
= (-7) / (25)
= -7/25
Answer:
There is only one solution
Step-by-step explanation:
14x + 2 = 10x + 5
Isolate the x to solve:
4x + 2 = 5
4x = 3
x = 
There is only one solution
This answer is already in simplest form so the answer is simply 5409/50
