Answer:
Step-by-step explanation:
Let
y ----> the altitude in feet
x ----> the time in seconds
we know that
The linear equation in slope intercept form is equal to
where
m is the slope ot unit rate
b is the y-intercept or initial value
In this problem we have
Your hot air balloon
The slope is equal to
The y-intercept is ---> represent a proportional relationship
The linear equation is
----> equation B
Another aircraft
The slope is equal to ---> is negative because is a decreasing function
The y-intercept is
The linear equation is
----> equation B
Equate equation A and equation B
solve for x
Adds 30x both sides
Divide by 34 both sides
12 + 32+ 14 feet, equals 58 feet
Answer:
-4x² - 5(x + 3) + x²
= -4x² - 5x - 15 + x²
= -3x² - 5x - 15
