Answer:
A. 525 feet
Step-by-step explanation:
If every hour their altitude increased by 135 then their would be an increase of 675 (135 × 5) after 5 hours. To find their altitude 5 hours earlier then you would subtract 675 from their current altitude. 1,200-675=525 feet
Answer:
208.00015
Step-by-step explanation:
Use a calculator. I'm sorry, there's no other way
The choices are in the slope-intecept form: y = mx + b, where m is the slope and b is the y-intercept. Looking at the graph, the y-intercept is the point at which it intersects the y-axis. That would be -1. So, the answer is either the 1st or 2nd choice. Next, we find the slope. Take 2 points that lie along the line. For example, points (1,2) and (2,5). Calculate for the slope.
m = (y2-y1)/(x2-x1)
m = (5-2)/(2-1)
m = 3
Hence, the graph is y = 3x - 1
Answer:
the answer is 15 subtract the highest number from the lowest
Answer: Reflection about x-axis
Step-by-step explanation:
Given
Initially, vertices are 
After reflection they become 
It is clear that the x coordinate remains unchanged and the y coordinate changes its sign. It occurs when reflection is done about the x-axis.
For example, when (a,b) is reflected about the x-axis, it becomes (a,-b).
So, here reflection is being done about the x-axis.
