Answer:
700 -1 -200
75 1 5000
Step-by-step explanation:
1. the rule for the required matrix is:
![\left[\begin{array}{ccc}x_1;y_1;a\\x_2;y_2;b\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7Dx_1%3By_1%3Ba%5C%5Cx_2%3By_2%3Bb%5Cend%7Barray%7D%5Cright%5D)
2. if to re-write the given equations, then:
700x-y= -200 and 75x+y=5000.
3. Finally, the answer is:
column№1 | column№2 | column№3
==============+===========+=============
row№1 700 | -1 | -200
row№2 75 | 1 | 5000
Answer:
- 3
Step-by-step explanation:
Differentiate f(x) using the power rule
(a
) = na
Given f(x) =
= 3
, then
f'(x) = - 3
= - 
f'(1) = -
= - 3
Answer:
21.6 feet
Step-by-step explanation:
Assuming the desk is a rectangular shape, you would find the perimeter of his desk.

OR
6.5 + 6.5 + 4.3 + 4.3
=21.6
Hope this helped! :)
