<=> cosx = +1/2 or cosx = -1/2;
cosx = +1/2 => x = +π/3 + 2kπ, where k is an integer or x = -π/3 + 2kπ, where k is an integer;
cosx = -1/2 => x = +2π/3 + 2kπ, where k is an integer or x = -2π/3 + 2kπ, where k is an integer;
I hope this helps. Keep in mind the 1/3 is slope and the 3 is y-intercept.
Answer:
$10.10
Step-by-step explanation:
$7.50 + $2.60 = $10.10
It is 3y because of the calculation being equivalent
Graph 1: -3 is the slope
Graph 2: 4/5 is the slope
