Answer:3

Step-by-step explanation:

3x+6=6x-3

Dave won a hot dog eating contest by eating 18 hot dogs in 10 minutes. He ate two more than twice the amount of the runner-up. W

IrinaVladis [17]

Answer:

The correct anser is option

B. 2x + 2 = 18

Step-by-step explanation:

Let the number of hot dogs eaten by the runner up be represented by x

If Dave ate 2 more than twice x, this means that the number eaten by him = 2x + 2

Since the total number of hot dogs eaten by Dave is 18

Therefore, the equation will be

2x + 2 = 18

So the number of hot dogs eaten by the runner-up is determined by solving for x

2x= 18-2

2× = 16

x = 16/2

x = 8

The runner up are 8

While Dave are

2×8 + 2 = 18.

What is the slope of the line through (-9,6) and (-6,-9)? Your answer must be exact.

iogann1982 [59]

The formula for slope is:

$m=\frac{y_{2}-y_{1}}{x_{2}-{x_{1}}$

So just plug in the values:

$m=\frac{-9-6}{-6+9}=\frac{-15}{3}=-5$

So $m=-5$ !

H(x) = −(x − 5)2 + 3

aleksandr82 [10.1K]

Max(f(x)) = f(3) = 4

Max(g(x)) = g(π/2) = 2

Max(h(x)) = h(5) = 3

Of these values, f(3) = 4 is the largest.

The function with the largest maximum is f(x).
