Answer:
The function f is graphed.
f is an even function as it has U- form.
As per the graph there is one local maximum at (0, 4) and one local minimum at (6, 1).
The global minimum is (-9, -2) and the global maximum is infinity.
The minimum and maximums are the borders of the increasing or decreasing intervals.
<u>Intervals when the function is increasing: </u>
<u>Intervals when the function is decreasing: </u>
Answer:
x=2, y=-3
Step-by-step explanation:
This type of problems is called a system of equations, or simultaneous equations.
When solving simultaneous equations, you need to first make sure you have two unknown terms of the same number but different signs - this is so one unknown cancels out because we can only solve when there's one unknown. We already have this ('2y' and '-2y'). Now we just add the 'x's, the 'y's and the numbers:
2x+2y=-2
3x-2y=12
(2x+3x)+(2y-2y)=(-2+12)
5x=10
x=2
Now that we know the value of x, use it to find y:
2x+2y=-2
2(2)+2y=-2
4+2y=-2
2y=-6
y=-3
The answer to the question is 4x - y ≥ 4

Answer:
35
Step-by-step explanation:
Alright this is like a linear pair. All three angles add up to 180; so this is the set up:
40 + 2x + 30 + 40 = 180
2x + 110 = 180
2x = 70
x=35
