Answer:
Do what it says and i'll give you the answer.
Step-by-step explanation:
1. Because the slopes are negative recipricals of each other then these lines are perpendicular. y=x+7 (red line) y=-x+2 (green line) +graph%28+300%2C ...
2.
When it comes to graphing, Desmos is a lifesaver!
I believe its B
Pi/3 is in the first quadrant, and all trigonometric functions are positive in the first quadrant,
Therefore, cos pi/3 is positive.
Answer:
279.50
Step-by-step explanation:
4,300 x 0.065 = 279.50. Hope this helps!
Step 1. Solve both inequalities for
:
Step 2. To check a point in the solution of the given system of inequalities, look for the intercepts of the lines
and
:
(1)
(2)
Replace (1) in (2):
Solve for
:
(3)
Replace (3) in (1):
We can conclude that the point (-2,3) is in the solution of the system if <span>
inequalities</span>
; also any point inside the dark shaded area of the graph of the system of inequalities is also a solution of the system.
