P=2a+b+c solve for c

Harman [31]

P = 2a + b + c

Subtract 2a + b on both sides

c = P - (2a+b)
c = P - 2a - b

Hope that helps :)

This graph shows a proportional relationship.<br> What is the constant of proportionality?

krek1111 [17]

hookes law gives the equation F=kx where F is the elastic force and k is the constant and x or small e is extension if we draw a graph you'll see that the graph increases by the same ratio every single time hence giving a straight line show that they are F and x are propotional to a certain limit

Solve for x

Ulleksa [173]

Answer:

C. x = 1

Step-by-step explanation:

To solve this problem the best way is to use the quadratic formula. First make everything equal to 0 by adding 3 to both sides.

3x^2 - 6x + 3 = 0

The quadratic formula is: $\frac{-b\pm\sqrt{b^2-4ac} }{2a}$ . Substitute the values of a, b, and c into the formula. Keep in mind:

a = 3
b = -6
c = 3

$\frac{-(-6)\pm\sqrt{(-6)^2-4(3)(3)} }{2(3)} \rightarrow \frac{6\pm\sqrt{36-4(9)} }{6} \rightarrow \frac{6\pm\sqrt{0} }{6} \rightarrow \frac{1\pm0}{1} \rightarrow 1$

Therefore, x = 1.
