Eight times a number plus 5 times another number is -13. The sum of the two numbers is 1. What are the numbers?

Answer:

The answer I think is

Step-by-step explanation:

After thoroughly calculating the simplifying the expression 164[3+2+ (9-7)] is   1148

An expression in mathematics is a combination of numbers, variables, and functions (such as addition, subtraction, multiplication or division etc.)

You can think of expressions as being similar to phrases. A phrase in language may contain an action on its own, but it does not constitute a complete sentence.

The following are some examples of expressions and word phrases that they relate to:

Formula: 3 + 7

Expressions and equations are different from one another because an expression consists of a combination of numbers, variables, and operation symbols, whereas an equation consists of two different expressions joined together by an equals sign. This shows that the expression's two sides have the same value.

Simplification of the expression 164[3+2+ (9-7)]

⇒ 164[3+2+ (9-7)] =

⇒ 164[5+(2)] =

⇒ 164[5+(2)]

⇒ 164(7)

⇒ 1148

The subtraction equation is 100 + (-45.43) = 54.57 and the number line is as shown in the attachment.

We want to write a subtraction equation with a difference of 54.57. The difference of 54.57 can be gotten from;

\100 + (-45.43) = 54.57

Now, if we draw the number above in a number line, it would be exactly as shown image attached. By careful observation, the difference is between 45 and 100 which are both whole numbers, but the exact difference as seen in the the red space.

Therefore, the subtraction equation is 100 + (-45.43) = 54.57

No extraneous solution to the equation

The equation is

2[tex](x - 1)^{4/1}[/tex] + 4 = 36

We have to find the extraneous solution of the equation and for this first, we need to find the value of x.

2[tex](x - 1)^{4}[/tex] + 4 = 36

2[tex](x - 1)^{4}[/tex] = 32

[tex](x - 1)^{4}[/tex] = 16

x - 1= 2

x = 3

Now we will put the value of x in the equation.

2[tex](3 - 1)^{4}[/tex] + 4 = 36

2 [tex]2^{4}[/tex] + 4 = 36

2 × 16 + 4 = 36

32 + 4 = 36

36 = 36

Step-by-step explanation:

The simplest form of the expression [tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} }[/tex] is [tex]\frac{1}{x}[/tex].

The simplest form of a fraction is one with a reasonably prime denominator and numerator. It indicates that, except for 1, there is no common factor between the fraction's numerator (upper portion or top) and denominator (lower part or bottom).

A fraction is a number that has been expressed as a quotient by dividing the numerator by the denominator. Both are integers in a simple fraction. In a complex fraction, a fraction can be found in either the numerator or the denominator.

An expression is made up of a number, a variable, or a combination of a number, a variable, and operation symbols. Two expressions joined by an equal sign form an equation.

Consider the expression,

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} }[/tex]

Now we know,

[tex]x^{-1}=\frac{1}{x}[/tex]

Therefore,

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{1}{\frac{x^4}{x^{-1}} })^{\frac{1}{5} }[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{x^{-1}}{x^4})^{\frac{1}{5}[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } =(\frac{1}{x \times x^4})^{\frac{1}{5}[/tex]

Using the exponential rule,

[tex]n^{b} \times n^{a} = n^{a+b}[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = (\frac{1}{x^{5}} )^{\frac{1}{5}[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = \frac{1}{x^{5 \times \frac{1}{5} }}[/tex]

[tex](\frac{x^{4}}{x^{-1}} )^{\frac{-1}{5} } = \frac{1}{x}[/tex]

The intensity level of the earthquake in New Madrid, Missouri in 1812 was about 1.6 times less than the intensity level of the earthquake Valdivia, Chile, in 1960.

We use the following formula for comparing the intensity level of earthquakes-

Log (i1 / i2) = M1 - M2

where i = intensity level determined by a seismograph

M = magnitude on a Richter scale.

Now, from the given information-

magnitude of earthquake in New Madrid = 7.9

Thus, M1 = 7.9

Then intensity of the earthquake in New Madrid = i1

magnitude of earthquake in Chile = 9.5

Thus, M2 = 9.5

Then intensity of the earthquake in Chile = i2

⇒ log (i1 / i2) = 7.9 - 9.5

log (i1 / i2) = -1.6

This means that the intensity level of the earthquake in New Madrid, Missouri in 1812 was about 1.6 times less than the intensity level of the earthquake Valdivia, Chile, in 1960.

The system of equations which is as represented in the task content above when solved by elimination, substitution or matrices has no solution.

This goes to say that the above given system of equations ultimately has no solution using matrices

It follows from the task content that the solution pair of the system of equation as given in the task content is to be determined.

Given system of equation;

4x-6y=9

-10x+15y = 8

By multiplying the first equation by 5 and the second equation by -2; we have;

20x - 30y = -16

Hence, it is evident that the system of equations above has equal slope but different intercept equations.

Consequently, subtract equation 2 from 1 so that we have;

the answer to the given logarithm expression is log₃ 125 = 3

Another technique to explain exponents in mathematics is through logarithms. A base number's logarithm equals another number.

The power's inverse function is the logarithm. For instance, log10 100 = 2 if 102 = 100. A power to which a number must be increased in order to achieve another value is referred to as a logarithm.

This is the most practical method for displaying enormous numbers. Logarithms have several important properties that prove that multiplication and division of logarithms can  be written in terms of addition and subtraction logarithms. A second name for the common logarithm is the base 10 logarithm.. This is represented as log10 or simply log. The base 10 logarithm is another name for the common logarithm. The common logarithm specifies the number of times the number 10 must be multiplied in order to produce the desired result.. We need to evaluate log₃ 125

Using the property

logₐ (mⁿ) = n logₐ m

125 = 5³log₃ 125 can be written as log₃ 125= 3 log₅ 5

We know that logₐ a = 13 log₅ 5= 3

Therefore, we calculated the logarithm, which is log₃ 125 = 3

log₃ 1/9

Can be written as:

log₃ (1/9) = x

using the log definition in exponential form. if x and b are positive real number and b dose not equal 1 then  log_b (x) = y is equivalent to b^y = x.

3^x = 1/9

So, i made this drawing to represent him and the tree, at a distance of 10 meters looking up at a 25* angle.

I marked the opposite side, adjacent side, and hypotenuse.

x is angle where you are "looking" from.  I.E., from the POV of mr watkins.

sin(x) = opposite/hyp

cos(x) = adj/hyp

tan(x) = opp/adj

So, we have an unknown side which is the opposite side, represented by length x.

The side adjacent is 10 meters.

The angle from him is 25 degrees.

What deals with adjacent and opposite?  Tangent.

Tan(25) = x/10

Solve for x.

10tan(25) is the height of the tree = 4.66

The height of the tree is 5 meters.

The corresponding growth factor of +500% is 6

The formula for the annual rate of change is

and ± sign depends upon whether it is a growth or decay factor. If it is growth factor then it is plus sign otherwise negative sign.

According to the question we have been given the growth that is +500%. Since there is plus sign therefore it is a growth factor.

Thus, r = + 5

The domain of the function h(x) = x² - x - 12 when the function operation f(x) = g(x) is performed is ( - ∞ , ∞ ).

A domain is a collection of potential input values. All input values visible on the x-axis make up the graph's domain. The collection of potential output values represented on the y-axis is known as the range.

Consider the two functions,

f(x) = x - 4 and g(x) = x² - 16

The function operation f(x) = g(x).

g(x) - f(x) = h(x)

x² - 16 - ( x + 4 ) = h(x)

h(x) = x² - x - 16 + 4

h(x) = x² - x - 12

The collection of input or argument values for which a function is actual and defined is known as its domain.

So, the domain of the function h(x) is ( - ∞ , ∞ ) or - ∞ < x < ∞.
