The solution is 22.5

To solve the given equation, rewriting the equation -

√(2x + 3) - 7 = 0

Shifting 7 to the Right Hand Side of the equation

√(2x + 3) = 7

Taking square on both sides of the equation

(√(2x + 3))² = 7²

Solving the square

2x + 3 = 49

Shifting 3 to the Right Hand Side of the equation

2x = 49 - 3

Performing subtraction on Right Hand Side of the equation

2x = 45

Shifting 2 to the Right Hand Side of the equation

x = 45 ÷ 2

Performing division on the Right Hand Side of the equation

x = 22.5

Hence, the solution is 22.5

Answer:

nonlinear

Step-by-step explanation:

In a linear equation, there are no multiplications of variables by variables.

x³ means x × x × x, so there is a multiplication of variables in the equation, and the equation is not linear.

Answer:

Non-linear

Step-by-step explanation:

Since one of the terms has an exponent of 3, this is a cubic equation, a third degree equation. It is a curve and therefore, NOT a linear equation.

With the help of the Magnitude formula, we can say that Magnitude of 1st vector is more than the 2nd vector.

A vector is an object that has both magnitude and direction. To find the size of a vector, we need to calculate the length of the vector. Variables such as velocity, distance, force, and momentum are vector variables. But velocity, mass, distance, volume, temperature, etc. is a scalar quantity. A vector has both magnitude and direction, while a scalar has only one magnitude.

The Magnitude of a vector is the length of the vector. The Magnitude value of vector a is represented by ∥a∥.

For a two-dimensional vector a= (a1, a2), the formula for its Magnitude is written below.

By using the Magnitude formula, we can say that Magnitude of 1st vector is more than the 2nd vector.

Step-by-step explanation:

Answer: x=296

Step-by-step explanation:

Answer:

1st question: $-4.5

2nd question: 32

3rd question: -27

Step-by-step explanation:

1st question:

Alan's octopus is $-7 dollars right now. After reloading $50 dollars in, it just means that he put $50 dollars in. We can work it out like this:

-7+50=43 (you can switch the equation around but the sign has to go with it: 50-7)

Now Alan's octopus has $43 in it. It then says that Alan spends $48.5 for a really expensive pencil case. You can calculate it like this:

43-48.5=-4.5 (43-48.5 is the same as 43.0-48.5 and you can work it out on a number line).

This leaves Alan's octopus to only have $-4.5 which means he is in debt again.

2nd question:

I can make it out that it says: Tony adds -18 to +50. Find the results (I hope I saw it right). The equation of it would look like:

-18+50 or you can flip it around but the sign has to go with them like in question one which will look like this: 50-18=32. So the result of Tony's problem is 32.

3rd question:

Patty subtracts +11 from -16. Find the results.

First of all don't do this 11-16 because that would be 16 subtracted from 11 which is wrong because 1, the sign completely disappears unless you make it -16 plus 11 and 2, it's order would be incorrect. The correct equation should look like this:

-16-11=-27 ( -16-(+11) positive combined with negative is negative).

You can think of it like this: If it's the same sign that's addition or subtraction eg. -4-2 or +6+8, you just add it up together and put the sign in front which you would not have to do for the addition one unless you are asked to.

After solving the equation ln 3x =6, the value of x is equal to [tex]\frac{e^6}{3}[/tex]

We have been asked to find x in ln 3 x=6

⇒ ln 3 x = 6

⇒ 3x = [tex]e^6[/tex]

⇒ x = [tex]\frac{e^6}{3}[/tex]

To solve linear equations, utilize the steps that are provided below.

Lets take an example of solve z for 7z – (3z – 4) = 12

Here is no multiplication or division, so this will be easy to solve

⇒ 7z – (3z – 4) = 12

⇒ 7z – 3z + 4 = 12

⇒ 4z = 12 – 4

⇒ 4z = 8

⇒ z = 8/4

⇒ z = 2

Distance = 65 ×0.25

Distance = 16.25 miles

18 > 16.25

Maxwell drove further. He drove 18 miles.

Answer:

D. Maxwell. He drove 18 miles,

Step-by-step explanation:

Distance = speed * time

Maxwell drives:

45 * 0.4 = 18 miles.

65 * 0.25 = 16.25 miles.

Using a proportional relationship, it is found that point (10.5, 42) makes sense in this context, as when x = 10.5, y = 42 is the output of the relation.

A proportional relationship is a function in which the output variable is given by the multiplication of the input variable and the constant of proportionality, defined by k, in the case of a direct relationship, according to the following rule:

y = kx

For the case of an inverse relationship, we have that:

y = k/x.

From the table in this problem, the constant is given as follows:

k = 28/7 = 32/8 = 36/9 = 40/10 = 4.

Hence the relation is modeled as follows:

y = 4x.

In which:

When x = 10.5, we have that:

y = 4(10.5) = 42.

Hence point (10.5, 42) makes sense in this context.

The rational number between the square root of 7 and the square root of 8 is 27/10

Rational expressions are expressions that are represented by the quotient of two polynomials or radicals.

This means that, a rational expression is represented by a fraction whose numerator and denominator are polynomials or radicals

The features of the rational number are given as

Value = between the square root of 7 and the square root of 8

Rewrite the value properly

So, we have

Value = between √7 and √8

Evaluate the values of √7 and √8

So, we have

√7 = 2.65

√8 = 2.83

This means that the rational number is between 2.65 and 2.83

A number between 2.65 and 2.83 is 2.7

Express as fraction

value = 27/10

Hence, the rational number between the square root of 7 and the square root of 8 is 27/10

The expression log₆5+log₆x as a single logarithm is log₆5x.

The logarithm is exponent's inverse function in mathematics. This indicates that the exponent to which a fixed number(say a) at base b, must be raised in order to create a  number x, is represented by the logarithm of that number.

For example if 8=2³ can be written in the logarithmic form as

log₂8=3.

The general properties of logarithm for a fixed base are:

Here the given logarithmic expression is (log₆5+log₆x)

So according to the properties of logarithms we can use the above property "logₐx+logₐy=logₐxy" to simplify the given expression.

Therefore:

log₆5+log₆x

=log₆(5×x)

=log₆5x

Hence written as a single logarithm the expression is log₆5x.
