Answer:
Step-by-step explanation:
The given function is
We need to find first partial derivatives of the function.
Differentiate partially w.r.t. x and y, z are constants.
Differentiate partially w.r.t. y and x, z are constants.
Differentiate partially w.r.t. z and x, y are constants.
Therefore, the first partial derivatives of the function are .
Answer:
Step-by-step explanation:
Therefore,
Answer:
Step-by-step explanation:
5x=y+6 --------- equ 1
2x-3y=4 -------- equ 2
5x - 6 = y
y = 5x - 6
substitute in equ 2
2x-3(5x - 6) =4
2x - 3*5x + 3*6 = 4
2x - 15x + 18 = 4
- 13x = 4 - 18
-13x = -14
x = -14/-13
x = 14/13
substitute in equ 1
5*14/13 = y+6
70/13 - 6 = y
y = ( 70 - 78)/13
y = -8/13
Answer:
60cm^2
Step-by-step explanation:
1. turn triangle into rectangle measuring 15x8
2. find area of rectangle (area = base*height): 8*15 = 120
3. Find area of triangle (divide rectangle area by 2): 120/2 = 60cm^2
So if his homework takes 25 minutes , and his math takes m minutes , and then as a while it takes h minutes, here’s an example of two equations you can use ;
M+25= h of 25+m=h you can do either one as you please because it doesn’t matter the order as long as they
Both equal h !! Hope this helps , sorry that it’s overdue :( have a great day:))))
