Answer:
Step-by-step explanation:
Let us assume that the eagle's elevation is 100 meters above.
We can multiply -14.2 by 0.8.
We now get -11.36.
We can add this to (-14.2*4).
We now get -11.36 + -56.8.
We can add those together to get the answer.
-11.36 + -56.8 = -68.16.
Then we can add that to 100 (since it is negative).
100 + (-68.16) = 31.84.
The eagle's elevation would be 31.84 meters if its starting position was 100 meters, meaning that the equation would be (a - 68.16).
Answer:
Equation of the perpendicular line is 
Step-by-step explanation:
Given equation is y = 5x - 4
By comparing this equation with slope-intercept form of the equation,
y = mx + b
Slope of this line 
Let the slope of the perpendicular line = 
By the property of perpendicular lines,
Equation of the perpendicular line passing through a point 
and slope m is represented by
If the given point is (10, -1) and slope 'm'= 
Answer:
f(x) = 9x - 1,200
Step-by-step explanation:
Let x represent the number of movie tickets sold.
9x will represent the profit made from selling movie tickets that day, since each ticket is 9 dollars.
To determine the profit, subtract 1,200 from 9x.
9x - 1,200 will represent the profit. Turn this into a function:
f(x) = 9x - 1,200 where x is the number of movie tickets sold and f(x) is the profit
Answer:
x = -11
Step-by-step explanation:
Add 9 to both sides of the equation
3 − 9 = −42
3 − 9 + 9 = −42 + 9
Simplify
Add the numbers
3 = −33
Divide both sides of the equation by the same term
3 = −33
3/3 = −33/3
Simplify
Cancel terms that are in both the numerator and denominator
Divide the numbers
= −11
