Answer:

The speed of the jet is 410 mph.

Step-by-step explanation:

The jet and the passenger plane flew in opposite directions.

Given that the passenger plane flew at a speed of 450 mph, then after 11 hours, the passenger plane will fly (450 × 11) = 4950 miles.

Again, given that after 11 hours the passenger plane and the jet are 9460 miles apart.

Therefore, in 11 hours the jet flew (9460 - 4950) = 4510 miles.

Hence, the speed of the jet is $\frac{4510}{11} = 410$ mph. (Answer)

The subtraction function

$(k-x)(x)$

is defined as the subtraction of the two equations, representing each function:

$(k-h)(x)=k(x)-h(x)$

So, we have

$(k-h)(x)=k(x)-h(x)=14x-2-(2x^3+4x-8)=-2x^3+10x+6$
