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:
C
Step-by-step explanation:
move the x over
-x+y=6
move the y over
-x = -y+6
times each number by a -
x=y-6
Answer:
the radius of the circle is 6cm
Step-by-step explanation:
the area of a circle is given to be = 36πcm²
radius of the circle = ?
to find the radius of the circle lets start by applying the formula for finding the area of a circle.
area of a circle = πr²
36πcm² = πr²
36π = πr²
divide both sides by π
36π/π = πr²/π
36 = r²
to get the value of r we are going to look for a way of getting rid of the square on "r" by squaring 36
r² = 36
r =√36
r = 6cm
therefore the radius of the circle is 6cm
Answer:
m= 8n-7/10
Step-by-step explanation:
n- 5/2 + 5/4 m= -27/8 + 2n
n- 5/2 + 5/4 m-n = -27/8 +2n-4
-5/2 +5 /4m=- 27/8 +n
- 5/2 + 5/4 m + 5/2 = - 27/8+n+ 5/2
5/4 m =n- 7/8
4. 5/4 m=4n -4 . 7/8
5m=4n- 7/2
5m/5 = 4n/5 - 7/2 /5
m= 8n-7/10
