Answer:
dy/dx = 
Step-by-step explanation:
-y + 2x²- x = -5y³
2x² - x = y - 5y³
4x - 1 = dy/dx - 15y².dy/dx
dy/dx(1 - 15y²) = 4x - 1
dy/dx =

Answer:
Trinomial
Step-by-step explanation:
This is because there are three terms involved in the equation. 
One of them is -7ab^4. Another is 4c^3. The third one is 25.
 
        
             
        
        
        
The sequence is " Algebraic, common difference = −10 " ⇒ 1st answer
Step-by-step explanation:
Let us revise the algebraic and geometric sequences
- The Algebraic sequence is the sequence that has a common difference between each two consecutive terms, like 2 , 5 , 8 , 11 , 14 , .......... the difference between the 5 and 2 is equal to the difference between 8 and 5, and the difference between 11 and 8 and the difference between 14 and 11
- The geometric sequences is the sequence that has a common ratio between each two consecutive terms, like 3 , -9 , 27 , -81 , ...... the ratio between -9 and 3 as the ratio between 27 and -9 as the ratio between -81 and 27
→  x   :    1    :    2    :    3    :    4
→ f(x) :    5   :   -5    :    -15  :    -25
x represents the positions of the terms
f(x) represents the value of each term
∵ 1st = 5 and 2nd = -5
∵ -5 - 5 = -10
∵ 2nd = -5 and 3rd = -15
∵ -15 - (-5) = -15 + 5 = -10
∵ 3rd = -15 and 4th = -25
∵ -25 - (-15) = -25 + 15 = -10
∴ There is a common difference -10 between each two 
    consecutive terms
∴ The sequence is algebraic with common difference -10 
The sequence is " Algebraic, common difference = −10 "

Answer:
350
Step-by-step explanation:
so the first step is to find the values of each of them 
7x10^6=7000000
2x10^4=20000
then we divide 7000000 by 20000
7000000/20000=350 
so the answer is 350 
hope this helps :)
