Answer:
The jet will cover 2585 miles in 11 hours.
Step-by-step explanation:
Given that:
Distance travelled by jet in 2 hours = 470 miles
Speed of jet =
Speed of jet = 470/2
Speed of jet = 235 miles per hour
Time = 11 hours
Distance travelled in 11 hours = Speed * Time
Distance = 235 * 11
Distance = 2585 miles
Hence,
The jet will cover 2585 miles in 11 hours.
Given:
The dotted boundary line passes through the points (-3,-8), (1,-2) and (9,10).
Above line is shaded.
To find:
The inequality for the given graph.
Solution:
Consider any two points on the line. Let the two points are (1,-2) and (9,10). So, the equation of the line is:
Multiply both sides by 2.
Above line is shaded and the boundary line is a dotted line. So, the sign of inequality must be >.
This inequality is not in the equations. So, multiply both sides by -1 and change the inequality sign.
Therefore, the correct option is D.
