Step-by-step explanation:

\frac{2a}{a + b - c}  =  \frac{2b}{b + c - a}  =  \frac{2c}{a + c - b}  = k \\  \\ by \: theorem \: on \: equal \: ratios \\   \\ \frac{2a + 2b + 2c}{a + b - c + b + c - a + a + c - b}  = k \\  \\  \frac{2(a + b + c)}{a + b + c}  = k \\ \\   \therefore \: k = 2

6th grade math, help me please
stira [4]

Answer:

1. 2/5

Step-by-step explanation:

When it says the ratio is 5 to 2, that means 5 is always first:

5 : 2 is correct

5/2 is correct

10 : 4 is correct (multiplied 2 on both sides)

2/5 is incorrect because 2 is first. That means that this ratio would be 2 to 5, not 5 to 2.

How to Find the vertex of f(x)=-8x^2-8x+7
charle [14.2K]

Answer:

The answer to your question is: (1/2, 5)

Step-by-step explanation:

Parabola                     f(x) = 8x² - 8x + 7

                                     y = 8x² - 8x + 7

Vertical Parabola equation

( x - h)² = 4p (y - k)            Transform the original equation to this form

8x² - 8x       = y - 7            

8(x² - x  + (   )²)  = y - 7       Complete squares

8 (x² - x + (1/2)²) = y - 7 + 2    Simplification

8 (x² - x + 1/4) = y - 5

                                 (x - 1/2)² = 1/8 (y - 5)

Finally Vertex

                        (1/2 , 5)
