Minimum is (5,0)
There is no maximum so maximum is N/A
Where the function is increasing is x>5
Function decreases where x<5
Answer:
zero product property of multiplication
Step-by-step explanation:
step 2 is valid, because for the main expression in step 1 to be true, only one of the 2 factors need to be 0, as
0 × something is always 0.
therefore, it is sufficient to find the values of x that renders the expression of one factor to 0.
Ok, so I worked out the problem.
So for part a) you just multiply 8 by 25% then add the product to get the new perimeter.
Part B you Add all sides for the original square and the new square to get the perimeters of each then you divide the old square perimeter by the new square perimeter to get the percentage.
Part C you get the areas pf bother squares then divide the old square area by the new square area to get the percentage change.
If you have any questions, let me know.
Answer:
11/20
Step-by-step explanation:
Solution
y = -3
y = 2x - 3
Substitute y for -3
-3 = 2x - 3
Add 3 to both sides
-3 + 3 = 2x - 3 + 3
Simplify the equation
0 = 2x
Switch sides so that the 2x is on the left side of the equation
2x = 0
Now divide both sides by 2
2x/2 = 0/2
Simplify the equation
x = 0
Therefore y = -3 and x = 0
