Solve for y
minus 10x from both sides
5y<-10x+15
divide both sides by 5
y<-2x+3
dot on top of earth = plane position at the time of observation (right one when 37°, left one 53°)
then the geometry is zoomed on the left side
Answer:
x = -2
Step-by-step explanation:
Step 1: Define
f(x) = -x - 5
f(x) = -3
Step 2: Substitute and Evaluate
-3 = -x - 5
2 = -x
x = -2
The answer is 2x^2-3x-2.
Just align the polynomials and combine like terms.
