Answer:
D. (2, 6)
General Formulas and Concepts:
<u>Algebra I</u>
- Solving systems of equations by graphing
Step-by-step explanation:
The solution set of the systems would be where the 2 lines intersect. We see from the graph that our 2 lines intersect at (2, 6). Therefore, our solution set would be D. (2, 6).
Answer:
Car a travels (300) miles in 6 hours
Car B travels (200) miles in 5 hours
Car A speed is (50) miles per hour
Car B speed is(40) miles per hour.
Car A traveled (faster than) Car B.
The graph for Car A is(steeper than) the graph for Car B
Step-by-step explanation:

where x is starting location and y is the ending location

the rest we see once we have solve for distance and speed of the 2 cars
Answer:
30 men
Step-by-step explanation:
In order to be sure that the sample mean does differ from the population mean by more than 0.90, the sample size (n) that should be used is given by:

Where 'Z' , for a 95% probability is 1.960, 's' is the standard deviation of 2.5 inches:

Rounding up to the nearest whole number, the sample size should be at least 30 men.
