We want to factorize 6x² + 7x - 10
Note that
6x² = x * 6x or 3x * 2x
10 = 2 * 5 or 1 * 10
We can obtain 7x as (6x)*(2) - (x)*(5) = 12x - 5x = 7x.
Therefore
6x² + 7x - 10 = (6x - 5)(x + 2)
Answer: (6x - 5)(x + 2)
To get the answer, you need to solve the equation for x = 7.
f(7) = 3/7 + 2 - sqrt(7) - 3.
= 3/7 - 1 - sqrt(7).
If you need to simplify it further:
= -4/7 - sqrt(7).
If you need it in decimal form: = -3.2171798824

Step-by-step explanation:
Car A: Started at 0 and ended at 300, thus, car A travels 300 miles.
It travels 6 hours, so car A speed is
mph.
Car B: Started at 100 and ended at 300, thus, car B travels 300-100=200 miles.
It travels 5 hours, so car B speed is
mph.
Since 50>40, car A traveled faster than car B.
The graph for the car A is steeper than the graph for the car B.
