Answer:
The less sign looks like a weird L the greater sign looks like a backwards L the equal sign means the two sides are equal. I hope this is the answer you were looking for
Step-by-step explanation:
Answer: you can use 260 min, 60 min at a fixed price ($20) and extra 200.
Step-by-step explanation:
C(x) = 20 + 0.20(x − 60)
C(x) ≤ 60
20 + 0.20(x − 60) ≤ 60
0.20(x − 60) ≤ 60 - 20
0.20x - 12 ≤ 40
0.20x ≤ 40 + 12
0.20x ≤ 52
x ≤ 52/0.2
x ≤ 260
This way, you can use 260 min, 60 min at a fixed price ($20) and extra 200.
Answer:
32
Step-by-step explanation:
36-4
Use Pythagorean theorem
(-3.5, 8)
You figure this out with the midpoint formula
3 types
There are three types of systems of linear equations in two variables, and three types of solutions. An independent system has exactly one solution pair (x,y) . The point where the two lines intersect is the only solution. An inconsistent system has no solution.
