Answer: The equation 3x + 2 = 3x - 2 has no solutions.

Step-by-step explanation:

So far, we know that we have four equations, and we have to find one that has no solutions. We can first examine them like Jubal did:

7x + 1 = 7x+ 1

3x + 2 = 3x - 2

4x + 1 = 3x + 8

-2x + 1 = -2x + 1

Just by looking at this, we see here that two of these equations look exactly the same even on the other side of the equation sign:

7x + 1 is the same as 7x + 1       AND

-2x + 1 is the same as -2x + 1

So we know that these are identities, meaning, they have infinitely many solutions. So, they cannot have no solutions because they are the ultimate opposite of that.

Next, looking at the other problems, we see that:

4x + 1 = 3x + 8       AND

3x + 2 = 3x - 2

Let's just take a look at the second equation from this selection. We see that this equation looks almost exactly the same on both sides of the equation sign, EXCEPT that the constants are different ( I mean 2 and -2 ). IF we WERE to add/subtract two from both sides, they wouldn't cancel out but instead leave you with 4. If you had subtracted the 3xs, then you would have been left with 0. So, 0 does NOT equal 6, so therefore, this has no solutions.

And what about 4x + 1 = 3x + 8?

If you just take a look at it, it only has one solution.

Hence, 3x + 2 = 3x - 2 has no solutions.

Answer:

n = 4

Step-by-step explanation:

3 + 4n + n = 2n +15

3 + 5n = 2n + 15

5n - 2n = 15 - 3

3n = 12

n = 12 / 3

  = 4

Answer:

N=4

Step-by-step explanation:

Simplifying

3 + 4n + n = 2n + 15

Combine like terms: 4n + n = 5n

3 + 5n = 2n + 15

Reorder the terms:

3 + 5n = 15 + 2n

Solving

3 + 5n = 15 + 2n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

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

3 + 5n + -2n = 15 + 2n + -2n

Combine like terms: 5n + -2n = 3n

3 + 3n = 15 + 2n + -2n

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

3 + 3n = 15 + 0

3 + 3n = 15

Add '-3' to each side of the equation.

3 + -3 + 3n = 15 + -3

Combine like terms: 3 + -3 = 0

0 + 3n = 15 + -3

3n = 15 + -3

Combine like terms: 15 + -3 = 12

3n = 12

Divide each side by '3'.

n = 4

Simplifying

n = 4

Answer:

CBE = 112.5 degrees

Answer:

x=13

Step-by-step explanation:

Q is the midpoint of PR

PQ + QR = PR

PQ= QR

PQ+QR = PR

QF + QR = PR

2QR = PR

2*43 = 9x-31

86 = 9x-31

Add 31 to each side

86+31 = 9x-31+31

117 = 9x

Divide each side by 9

117/9 = 9x/9

13 =x

Answer:

x = 13

Step-by-step explanation:

since Q is the midpoint of PR and QR is 43, then

PR = QR * 2 ⇒ 43 * 2 = 86

PR = 9x - 31

⇒ 9x - 31 = 86

⇒ 9x = 86 + 31

⇒ 9x = 117

Divide both sides by 9 ⇒ [tex]\frac{9x}{9} = \frac{117}{9}[/tex]

⇒ x = 13

It is convenient to start with a point-slope form of the equation.

  y = m(x -h) +k . . . . . line with slope m through point (h, k)

__

6) m = -7, (h, k) = (2, -3)

  y = -7(x -2) -3 = -7x +14 -3

  y = -7x +11

__

8) m = -1/3, (h, k) = (-3, 0)

  y = (-1/3)(x -(-3)) +0

  y = -1/3x -1

__

10) m = 5/4, (h, k) = (4, 3)

  y = 5/4(x -4) +3 = 5/4x -5 +3

  y = 5/4x -2

The square root of the given number is 5i√3. Therefore, option D is the correct answer.

The square root of a number is the inverse operation of squaring a number. The square of a number is the value that is obtained when we multiply the number by itself, while the square root of a number is obtained by finding a number that when squared gives the original number.

The given number is √(-75).

Here, √(-75) can be written as √(-25×3)

Answer:

d linear

Step-by-step explanation:

It looks a bit like a linear equation

The function g(x) = 5x - 3 is a linear function as the degree of x is one.

An equation of degree one is known as a linear equation.

A linear equation of two variables can be represented by ax + by = c.

g(x) = 5x - 3 is not a constant it is a function in x.

g(x) = 5x - 3 is not a quadratic function as the degree of x is one.

g(x) = 5x - 3 is also not an absolute function as we can see.

Hence g(x) = 5x - 3 is a linear function as the highest power of x or the degree of x is 1 and it is a linear function in variable x.

Answer:

y = 17.5

Step-by-step explanation:

y is directly proportional to x means that

y = k.x

when y=5, x=2 --> k = y/x = 5/2

when x=7

y = k.x = 5/2 . 7 = 35/2 = 17.5

If y is directly proportional to x and y = 5 when x = 2 the value of y is 17.5

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that  y is directly proportional to x

y = 5 when x = 2

We need to find the value of y when x is 7

To find the value of y when x is 7 we have to construct a proportional formula as below

2/5=7/y

Apply cross multiplication

2y=35

Divide both sides by 2

y=35/2

y=17.5

Hence, If y is directly proportional to x and y = 5 when x = 2 the value of y is 17.5

Answer:

y = -1

Step-by-step explanation:

1y + 14 = -4y + 9

Isolate the variable, y. Note the equal sign, what you do to one side, you do to the other. Add 4y and subtract 14 from both sides:

1y (+4y) + 14 (-14) = -4y (+4y) + 9 (-14)

1y + 4y = 9 - 14

5y = -5

Divide 5 from both sides:

(5y)/5 = (-5)/5

y = -5/5 = -1

-1 is your answer for y.

The average is the middle value of a set of numbers. This isn't to be confused with the median, which is the middle of a set of numbers. The average is the middle value of the numbers. If you need to find the average of a set of numbers, you add them all together and divide by the amount of numbers.

Formula of average:

According to the question

A student has scores on four quizzes : 85,83,98,77

she score on the fifth quiz to have an average of at least 84

Let fifth quiz score = x

By using formula of average:

[tex]Average = \frac{Sum of terms }{Number of terms }[/tex]

As average should be at least 84

[tex]84 < \frac{85+83+98+77+x }{5 }[/tex]

Answer:

Max is 9 feet above Brett.

Step-by-step explanation:

If you subtract how far Max is below the surface to how far Brett is below the surface you find the difference of how much more above Brett Max is.

This would be the mathematical process:

34-25=9

Max is 9 feet above Brett.

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

Given that Brett is 34 feet below the surface and Max is 25 feet below the surface.

Max is more than twice as deep below the surface as Brett,

Thus we can determine this difference by subtracting Max's depth from Brett's.

The mathematical solution would be as follows:

⇒ 34 - 25

⇒ 9

Hence, Max is 9 feet above Brett.
