Step-by-step explanation:
5x + 2 < 4x - 3
5x - 4x < -3 - 2
x < -5
Answer:
77% is greater than 3/5
3/5 = 0.60
Which as a percent is 60 % after moving the decimal to the right two places (multiply by 100)
20*15=300
It's "too short", but there's not much else to say here.
Answer:
Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m
Step-by-step explanation:
Let
x -----> the time in seconds
y ----> altitude in meters
we have


This is a vertical parabola open upward
The vertex is a minimum
To find out the lowest altitude, find the vertex
Complete the square
Factor the leading coefficient


Rewrite as perfect square


The vertex is the point (50,-125)
therefore
Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m (below the sea level)
