Answer:

(goh) (4) = 7

Step-by-step explanation:

(goh) (x) = g(h(x))

Plug in

g(h(x)) = 5(√x) - 3

if x = 4 then

g(h(4)) = 5(√4) - 3

g(h(4)) = 5(2) - 3

g(h(4)) = 10 - 3

g(h(4)) = 7

Which ordered pair is a solution of this

natali 33 [55]

Answer:

(- 3, 2 )

Step-by-step explanation:

To determine which ordered pair is a solution, substitute the x and y- coordinates of the given points into the left side of the equation.

If the result is equal to the right side then the pair is a solution.

(2, - 2)

- 6(2) - 7(- 2) = - 12 + 14 = 2 ≠ 4 ← not a solution

(- 2, 2 )

- 6(- 2) - 7(2) = 12 - 14 = - 2 ≠ 4 ← not a solution

(- 3, 2 )

- 6(- 3) - 7(2) = 18 - 14 = 4 = right side ← a solution

(2, - 3 )

- 6(2) - 7(- 3) = - 12 + 21 = 9 ≠ 4 ← not a solution

(- 3,2 ) is a solution of the equation

Zanzabum

Answer:

Step-by-step explanation:

Put the values of P and Q to the equation Px - 45 = Qx + 75:

15x - 45 = 15x + 75 subtract 15x from both sides

-45 = 75 FALSE

In other cases, we get some value x.

Example:

A. P = -45 and Q = -75

-45x - 45 = -75x + 75 add 45 to both sides

-45x = -75x + 120 add 75x to both sides

25x = 120 divide both sides by 25

x = 4.8

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:

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

$m = \frac{-16}{1}$

$m = -16$

Since both slopes are not the same, the relationship be modeled by a linear function
