Distributive property. the property used is distributive property.
Hello here is a solution :
<span>direct variation equation relates x and y is : y = 10x</span>
X=2W+1-1/Y
YOU SUBTRACT 2/Y TO START TO GET X ALONE.
WHICH WOULD MAKE IT 2X=4W+2-2/Y.
THEN YOU MUST DIVIDE BOTH SIDE BY TO FINISH GETTING X ALONE WHICH WOULD GIVE YOU YOUR ANSWER
Hello :
y² =x^3+3x²
the derivate is : 2yy' = 3x²+6x
where x= 1 and y = 2
2(2)y' = 3(1)²+6(1)
4y' = 9
y' = 9/4
an equation at (1.2) is : y = (9/4)(x-1)+2
y= (9/4)x-1/4
