Answers

Answer: A, C, A, B

Step-by-step explanation:

For all of these, we can use indecy laws such as when there is a power of a power, you can multiply the powers.

Using this, we get 6^-3 x -1 or,

6^3

For the second one we get (6)^-3 x 3 or,

6^ of negative 9 which is neither.

I am guessing that the last 2 are fractions. (1/6)^-3 is equal to 216 which is 6^3.

For the last one, (1/6)^3 is basically the opposite so the answer is 6^-3.

Which statement about the solving process when an equation has no solution or infinite solutions is TRUE?
The variable will always end up on the left-hand side of the equation.
The constant terms will always be a multiple of 3.
Collecting the like terms will result in the elimination of the variable.
Gathering the like constant terms will always result in the value 0.

Answers

Answer:

A

Step-by-step explanation:

The variable will always end up on the left-hand side of the equation

The statement that is true about the solving process when an equation has no solution or infinite solutions is: “The variable will always end up on the left-hand side of the equation.” Hence, Option A is correct.

What are infinite solutions?

Both sides are equivalent in an endless solution. For instance, 12x + 4y - 16 = 6x + 2y - 8 Using a formula or method for infinite solutions, one can simplify the equation and make both sides equal to one another, making it an infinite solution. Infinity is a symbol for boundlessness or infinity. The sign "" is typically used to denote it.

When the lines are parallel and they share the same y-intercept, the system of equations has an infinite number of solutions. If the slope and y-intercept of two lines match, they are in fact the exact same line. The variable, which always appears on the left side of the equation, has infinite solutions.

Therefore, Option A is correct.

This table shows the populations of the four largest cities in the state of Wyoming. How many more people live in Cheyenne than in Laramie?

Answers

Answer:

28650

Step-by-step explanation:

just subtract 59,466-30,816

The number of more people who live in Cheyenne than in Laramie given the population of each city in the state is 28,650 people

How many more people live in Cheyenne than in Laramie?

Population can be defined as the total number of people living in a particular geographical location at a period of time.

Population of Cheyenne = 59,466

Population of Laramie = 30, 816

The number of more people who live in Cheyenne than in Laramie = Population of Cheyenne - Population of Laramie

= 59,466 - 30, 816

= 28,650 people

Hence, 28,650 more people live in Cheyenne than in Laramie.
