Answer:
w = -7/4
Step-by-step explanation:
-3w - 4 = w + 3
-3w - w = 3 + 4
-4w = 7
w = -7/4
Answer:
Coordinates of X is (7/2,9/2)
Coordinates of C is (6,7)
Explanation:
x is the midpint of DB and AC
coordinates of X = ( (5+2)/2 ,(6+3)/2)
= (7/2,9/2)
Coordinates of X is (7/2,9/2)
Let (a,b) be the coordinates of C.
Then,
coordinates of x = ((a+1)/2, (b+2)/2)
(7/2,9/2) = ((a+1)/2, (b+2)/2)
Hence,
7/2=(a+1)/2
7=a+1
a = 6
9/2 =(b+2)/2
9 =b+2
b =7
Coordinates of C is (6,7)
Answer:
![\left[\begin{array}{ccc}-32\\4\\20\\-36\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-32%5C%5C4%5C%5C20%5C%5C-36%5Cend%7Barray%7D%5Cright%5D)
Step-by-step explanation:
The product of a scalar times the matrix involves the product of that scalar times each of the elements of the matrix, resulting on the multiplication by "-4" of each of the four elements as shown below. These new product values end up being the new matrix elements.
![-4*\left[\begin{array}{ccc}8\\-1\\-5\\9\end{array}\right] = \left[\begin{array}{ccc}-32\\4\\20\\-36\end{array}\right]](https://tex.z-dn.net/?f=-4%2A%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D8%5C%5C-1%5C%5C-5%5C%5C9%5Cend%7Barray%7D%5Cright%5D%20%3D%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D-32%5C%5C4%5C%5C20%5C%5C-36%5Cend%7Barray%7D%5Cright%5D)
Answer:
it's C
Step-by-step explanation:
Imagine a coordinate plane. Move 5 units away, you'll end up with (-5, 2).
