16mph
Step-by-step explanation:
128 ÷ 8 = 16
<em>good luck, i hope this helps :)</em>
Do 2/5+5/7 and there's your answer. 2/5+5/7=14/35+25/35=39/35=1 4/35. :)

The distance from a point to a line is
distance(ax+by+c=0,(x0,y0)) = abs(ax0+by0+c)/sqrt(a^2+b^2)
So first convert the formula for the line to standard form
5x+2y=4
5x+2y-4=0
a=5, b=2, c=-4, x0=15, y0=-21
abs(5*15+2*(-21)-4)/sqrt(5*5+2*2)
= abs(75-42-4)/sqrt(25+4)
= 29/sqrt(29)
= sqrt(29)
= 5.385165 (approximately)
I assume you are studying implicit differentiation. Solving for dy/dx.
For the Left side use product rule. For Right side, use chain rule. Remember any time you take derivative of "y-term" you must multiply it by dy/dx.

Get dy/dx terms on one side:

Factor out dy/dx and solve:
