The answer is (1,-10)

You solve this by equating the two equations:
-x2 -5x -4 = -x2 +9x -18
-14x = -14
x =1

You then substitute 1 to either of the equations to find y:
y = -(1)2 -5(1) -4
y = -10

Therefore, the solution is (1,-10)

Answer:

The approximate probability is 0.7325.

Is not unlikely that a driver in that age bracket is involved in a car crash during a​ year, so there are reasons to be concerned.

Step-by-step explanation:

The approximate probability can be estimated using the sample proportion:

p=\dfrac{X}{n}=\dfrac{293}{400}=0.7325

A probability of 0.7325 is high, so it is not unlikely that a driver in that age bracket is involved in a car crash during a​ year.

As this value is high, there is reasons to be concerned about it.
