Solve the equation: 3x − x − 5 = 2(x + 2) − 9 No solution, 1, All real numbers, 0

Answers

Answer:

I hope this helps

Step-by-step explanation:

Simplifying

3x + -1x + -5 = 2(x + 2) + -9

Reorder the terms:

-5 + 3x + -1x = 2(x + 2) + -9

Combine like terms: 3x + -1x = 2x

-5 + 2x = 2(x + 2) + -9

Reorder the terms:

-5 + 2x = 2(2 + x) + -9

-5 + 2x = (2 * 2 + x * 2) + -9

-5 + 2x = (4 + 2x) + -9

Reorder the terms:

-5 + 2x = 4 + -9 + 2x

Combine like terms: 4 + -9 = -5

-5 + 2x = -5 + 2x

Add '5' to each side of the equation.

-5 + 5 + 2x = -5 + 5 + 2x

Combine like terms: -5 + 5 = 0

0 + 2x = -5 + 5 + 2x

2x = -5 + 5 + 2x

Combine like terms: -5 + 5 = 0

2x = 0 + 2x

2x = 2x

Add '-2x' to each side of the equation.

2x + -2x = 2x + -2x

Combine like terms: 2x + -2x = 0

0 = 2x + -2x

Combine like terms: 2x + -2x = 0

0 = 0

Solving

0 = 0

Couldn't find a variable to solve for.

This equation is an identity, all real numbers are solutions.

What is the length of segment BC?

Answers

The length is 10 because this is a right triangle and based on the pythagorean theorem, the sum of the squares of the legs equals the square of the longest side.

6 squared plus 8 squared is 100, which is 10 squared.

The answer is 10.

Answer:

C. 10

Step-by-step explanation:

The Pythagorean Theorem states that a² + b² = c²

a² can be found by multiplying 6 by 6, which is 36

b² can be found by multiplying 8 by 8, which is 64

36 + 64 = 100.

The square root of 100 is 10, you can double-check this because 10 x 10 = 100

Because of this, we know that the line segment BC is equal to 10

what is the slope and y-intercept of y=4x+2

Answers

Answer:

slope: 4

y-intercept: 2

Step-by-step explanation:

We are given an equation, y = 4x + 2, and we are asked to find the slope and y-intercept of the line. Looking carefully, we can see that the equation is given to us in slope-intercept form.

Slope-intercept form is:

y = mx + b

where m is the slope and b is the by-intercept.

Knowing this, we can find that 4 is the slope of the line and 2 is the y-intercept.

You invest $1000 in an account that has an annual interest rate of 4%, compounded monthly for 12 years. What is the equivalent interest rate and how many times will the money be compounded?
0.33% and 1 time
3% and 4 times
3% and 144 times
0.33% and 144 times

Answers

Answer:

The final balance is $1,612.23.

The total compound interest is $612.23.

Step-by-step explanation:

The required equivalent interest rate and money compounded is 0.33% and 144 times respectively. Option b is correct.

Equivalent interest rate for 4% and how many times the money will be compounded to be determine.

What is arithmetic?

In mathematics it deals with numbers of operations according to the statements.

Here, the equivalent interest rate = 4%/12
                                                     = 1/3
                                                     = 0.33%


Now, number of times money compounded = 12 years
                                                                    = 12 x 12 months
                                                                    = 144

Thus, the required equivalent interest rate and money compounded is 0.33% and 144 times respectively.
