How do I solve -0.4r=16?
Leviafan [203]

Answer:

r = -40

Step-by-step explanation:

1. Move constants to the other side of the equation

r = 16/-.04

2. Simplify (by calculator)

You can use a calculator and plug in 16/-.04

r = -40

2. Simplify (by fraction)

You can turn -.4 into a fraction.

-.04 = - 4/10

r = 16/-(4/10)

r = 16*10/-4

r = -40

Round 1 of a tennis tournament starts with 64 players. After each round, half of the players have lost and are eliminated from t
Nostrana [21]

Answer:

It can not be modeled by a linear function

Step-by-step explanation:

The given parameters can be represented as:

(x_1,y_1) = (1,64)

(x_2,y_2) = (2,32)

(x_3,y_3) = (3,16)

Where: x = rounds and y = players

Required:

Determine if it can be represented by a linear function

To do this, we simply calculate the slope (m)

m = \frac{y_2 - y_1}{x_2 - x_1}

and

m = \frac{y_3 - y_2}{x_3 - x_2}

Using: m = \frac{y_2 - y_1}{x_2 - x_1}, we have:

m = \frac{32 - 64}{2 - 1}

m = \frac{-32}{ 1}

m = -32

Using m = \frac{y_3 - y_2}{x_3 - x_2}, we have:

m = \frac{16 - 32}{3 - 2}

m = \frac{-16}{1}

m = -16

<em>Since both slopes are not the same, the relationship be modeled by a linear function</em>
