Answer:
w-2u-v
Step-by-step explanation:
Given are three vectors u, v and w.
In R^2 we treat first element as x coordinate and 2nd element as y coordinate.
Thus we mark (1,2) in the I quadrant, (-3,4) in II quadrant and (5,0) on positive x axis 5 units form the origin.
b) 
We have to find the values of a and b
]
Equate the corresponding terms

Divide II equation by 2 to get

Eliminate a
-5 = 5b: b=-1
a=-2
Hence
w = 2u-v
Answer:
The point-slope form of the line is:

Hence, option B is correct.
Step-by-step explanation:
We know the point-slope form of the line equation is
where
- m is the slope of the line
Given
The slope m = 4
From the graph, we can take the point (-3, -4)
So, in our case:
(x₁, y₁) = (-3, -4)
m = 4
now substituting m = 4 and (x₁, y₁) = (-3, -4) in the point-slope form of the line equation



Therefore, the point-slope form of the line is:

Hence, option B is correct.
- The graph of the line is also attached.
Given:
40 people
box plot data:
minimum age : 20
Q1: 28
Median: 34
Q3: 42
maximum age: 48
Q1 represents 25% of the data set.
40 x 25% = 10
There are 10 people who are aged 28 and below.
1st quartile is equal to 25% of the data set, the median is equal to 50% of the data set, 3rd quartile is equal to 75% of the data set.
Answer:
it's B
Step-by-step explanation:
the text gives you clues "times" is a form of multiplication. therefore it would be 8 TIMES 4
