Expression:

The expression means a mathematical statements that have two terms at least that contain variables, numbers, or both connected by the arithmetic operators.

Given,

Here we have the expressions 2x + 1 = y and y = 2x + 1.

Now, we have to find the number of solution for this expression.

When we try to find the solution(s) graphically, you would plot both of the equations as straight lines. The solution(s) lies where the lines intersect.

But here we looking into the given equation both are equal.

And if we plot these on the graph then it will simply present the straight line. And there is no intersection in it.

At a local high school, GPA's are normally distributed with a mean of 2.9 and standard deviation of 0.6.

x=4.25 is the GPA highest 2.5% of the students.

We have to find the GPA of the highest 2.5% of the students.

Mean = μ = 2.9

Standard deviation = σ = 0.6

Finding the z value for corresponding area 0.9750

For 95% confidence interval ,

z = 1.96

For 97.5% confidence interval,

We get z = 2.25

From

Z = ( x - μ ) / σ

For 2.5% of the students

To solve for x

x = Z*σ + μ

x = 2.25*0.6 + 2.9

x = 1.35 + 2.9

x = 4.25   GPA of highest 2.5% of students

Hence the answer is, x=4.25 is the GPA highest 2.5% of the students.

The equation that could be used to determine x, the number of seconds, when the two tanks have the same amount of water is 120 - 1/2(x) = 100 - 1/4(x) or x = 80.

An algebraic expression is the combination of numbers and variables in expressing and solving a particular mathematical question. An equation is the equality of expressions.

Let x be the number of seconds at the moment that the two tanks have the same amount of water.

If a tank has 120 gallons of water and is being drained at a rate of 1/2 gallon each second, the the amount of water left after time = x is "120 - 1/2(x)".

If another tank has 100 gallons of water and is being drained at a rate of 1/4 gallon each second, the the amount of water left after time = x is "100 - 1/4(x)".

Equate the two expressions to determine the time, x , at which the two tanks have the same amount of water left.

120 - 1/2(x) = 100 - 1/4(x)

The division of the fraction 27/22 will result to 1.22 rounded to the nearest hundredth.

To divide the fraction using long division, we first divide the dividend with the divisor, write the whole number result, and then multiply it by the divisor, subtract the result from the dividend to get a new dividend. Repeat the process for the new dividend until you arrive at a remainder of zero, or continue to a given place value.

27/22 = 1 whole number and a remainder of 5

1 × 22 = 22

27 - 22 = 5

drop the value for the tenth digit of 27.00 which is 0 to yeild 50{ new dividend}

50/22 = 2 whole number and a remainder of 6

2 × 22 = 44

50 - 44 = 6

drop the value for the hundredth digit of 27.00 which is 0 to yeild 60{ new dividend}

60/22 = 2 whole number and a remainder of 16

2 × 22 = 44

69 - 44 = 16

we are rounding up to the nearest hundredth, we stop with the quotient of 1.222.

Hence, the fraction 27/22 is equal 1.22 rounded up to the nearest hundredth using the long division process.

The 3rd degree equation that is divisible by x, (x − 3), (x+1) is x³ - 2x² - 3x.

A cubic polynomial is a sort of polynomial that is based on the variable's largest exponent, or degree, in mathematical terms. As a result, a cubic polynomial is one in which the degree or maximum power of the variable is 3. An algebraic statement having variables, constants, and exponents that are whole integers is called a polynomial.

The given factors are x, (x - 3), (x + 1)

To find the 3rd-degree polynomial divisible by x, (x - 3), (x + 1) multiply the three expressions.

First multiply x, (x - 3)

x × (x - 3)

= x × x - 3 × x

= x² - 3x

Now multiply x² - 3x and (x +1)

(x² - 3x) × (x + 1)

= x²(x) - 3x(x) + x²(1)  - 3x(1)

= x³ - 3x² + x² - 3x
= x³ - 2x² - 3x

So, this is the 3rd-degree equation that is divisible by x, (x − 3), (x+1).

The amount owed at the end of the 6 years duration is $10865

The given parameters about the compound interest are

Principal Amount, P = $5300

Interest Rate, R = 8%

Time, t = 6 years

To calculate the amount owed, we make use of the following formula

A = P + CI

Where

Compound interest, CI = P(1 + R)^t - P

So, the equation becomes

A = P + P(1 + R)^t - P

Evaluate the like terms

A = P(1 + R)^t

In this question, the formula is given as

A = P(1 + r/n)^nt

Where

n = 12, i.e compounded monthly

Substitute the known values in the above equation

A = 5300 * (1 + 8%/12)^(6*12)

Express 8% as decimal

A = 5300 * (1 + 0.08/12)^(6*12)

Evaluate the sum

A = 5300 * (1.01)^(6*12)

Evaluate the exponent

A = 5300 * 2.05

Evaluate the product

A = 10865
