Recall that the derivative of a constant is 0.

\bf y=x^2-4x+4\implies y=(x-2)^2\implies \stackrel{inverse}{x=(y-2)^2}
\\\\\\
\sqrt{x}=y-2\implies \sqrt{x}+2=y\implies x^{\frac{1}{2}}+2=y
\\\\\\
\cfrac{1}{2}x^{-\frac{1}{2}}+0=\cfrac{dy}{dx}\implies \cfrac{1}{2}x^{-\frac{1}{2}}=\cfrac{dy}{dx}

C. There is no solution.

6(x+4)=5(x-5)+x
6x+24=5x-25+x
6x+24=6x-25
24=-25
The statement is false for any value of x
∴ There is no solution.

A traveler traveled for 6 hours and covered a distance of 520 km. He traveled the first 260 km by car, and the rest of the way b
Shkiper50 [21]

Answer:

57.78 km/hr

Step-by-step explanation:

Total time taken, t = 6 hours

Total distance covered, d = 520 km

Distance by car = 260

Distance by train = 520 - 260 = 260 km

Train speed = x

Car speed = 2x

Average speed speed = 3x /2

Speed = distance / time

1.5x = 520 / 6

9x = 520

x = 520 / 9

x = 57.777

Average speed of train = 57.78 km/hr

Snezhnost [94]

Answer:

x = 28

Step-by-step explanation:

With 3 angles I'm guessing its a triangle so all triangles equal 180 degrees

42 + 110 = 152

180 - 152 = 28
