Xavier plays a video game that allows him to control many different characters.

Each character starts the game with 200 gold coins.

Each character receives 30 gold coins for each month that passes within the game.

Xavier controls 50 characters in the video game.

Which function shows the relationship between A(x), the total number of gold coins that Xavier has collected playing the game, and x, the number of months that have passed within the video game?

Your answer would simply be C. A(x) = 50(30x + 200)

Answer:

It would be 24m

Step-by-step explanation:

The longest side of a right triangle is the hypotenuse.

Use the Pythagorean theorem to solve for the hypotenuse:

X = sqrt(7^2 + 24^2)

X = sqrt( 49 + 576)

X = sqrt(625)

X = 25

The longest side is 25m

Answer:

The answer is 30

Step-by-step explanation:

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

If 60% of nickel is present in the metal bar that weighs 50 ounces.

The amount of ounces of nickel in the metal bar is 30 ounces.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% of 100 = 50/100 x 100 = 50

20% of 40 = 20/100 x 40 = 8

We have,

Weight of the metal bar = 50 ounces.

The percentage of nickel in the metal bar = 60%

The amount of nickel in the metal bar:

= 60% of 50 ounces

= 60/100 x 50 ounces

= 30 ounces

Thus,

If 60% of nickel is present in the metal bar that weighs 50 ounces.

The amount of ounces of nickel in the metal bar is 30 ounces.

Step-by-step explanation:

[tex]\frac{x}{5}[/tex] + 6 < 2

subtract 6 from both sides of the equation

[tex]\frac{x}{5}[/tex] < 2 - 6

[tex]\frac{x}{5}[/tex] < -4

multiply both sides of the equation by 5

x < -4 * 5

x < -20

Answer:

seems like this.

Step-by-step explanation:

From set theory, the factorial combinations are 2^N where N are the number of induvidual mambers of the set and that includes the null set. If we require that one element be the minimum to form a set, this eliminates the empty set (and there is only one empty set) so we must subtract one from the formula. The correct answer is therefore 2^N-1. In this case that is 2^5–1 = 31.

Answer:

x + 8 = x8

Step-by-step explanation:

This is one of the many ways to rewrite this equation. The reason this is a way of rewriting it is because 3x plus 5x equals 8x and if you take away the variable from 3 and 5 and add the numbers together you get 8. So take the variable x add it to 8 and you get x8. Both equations have the same answer so therefor this is another way of writing the equation.
