Two planes, a and b, start from the same place and move in different directions, making an angle of 50º between them. the speed of plane a is 200 miles per hour, and the speed of plane b is 300 miles per hour. the two planes are miles apart after one hour.

x is variable or an unknown value to find

example:

2x = 5 which means x = 3

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
