The simplified polynomial is; xy(x²y - xy² +1) and; the value when x=-3 and y=2 is; -186
From the polynomial given;
The polynomial can be factorised to yield a simpler form as follows;
This is so because, xy is a common factor.
The value is therefore;
- (-3×2)((-3)²2 - (-3×2²) +1)
= -186

Answer:
(1,2)
Step-by-step explanation:
y = 2x. y = -x+3
Set the two equations equal
2x = -x+3
Add x to each side
2x+x = -x+x+3
3x = 3
Divide by 3
3x/3 = 3/3
x = 1
Now find y
y =2x = 2(1) = 2
(1,2)
Answer:
A' (3/2, -9/4)
B' (-3, 9/4)
C' (3/2, 9/4)
Step-by-step explanation:
1. You have the following coordinates of the vertices of the triangle ABC:
A (-2, 3) B (4, -3) C (-2, -3)
2. The given scale factor is -3/4, therefore, to calculate the coordinates of the triangle A'B'C', you must multiply each coordinate of the triangle ABC by the scale factor.
3. Therefore, you obtain that the the coordinates of the triangle A'B'C' are:
A'=((-2)(-3/4), (3)(-3/4))=(3/2, -9/4)
B'=(4(-3/4), (-3)(-3/4))=(-3, 9/4)
C'=((-2)(-3/4), (-3)(-3/4))=(3/2, 9/4)
Answer:
Example: the median is not affected by very large or very small values (outliers).
Step-by-step explanation:
Suppose my income for 5 months is $1000, $1500, $1550, $2000, $90,000. (I hit the lottery in the last month!).
The median is the number in the middle: $1550. That $90,000 would increase the <u>mean</u> ("average") by a lot, but the median is unchanged.
If a newspaper story reports the median house price in a neighborhood is $93,000, that million dollar mansion on the corner won't change the median. Half the prices are less than $93,000 and half are greater.
It would be 50 times because 15 divided by 3 is 5 and you just add your 0 back and get 50! hope this helps!
