Is the function x =- 1 even or odd?

Answer:

-7x = 10

Step-by-step explanation:

step 1:  multiply each term inside the parentheses by -5, to get:

-5x + 5 = 2x + 15

you can subtract 2x from each side of the equation to get:

-7x + 5 = 15

now you subtract 5 from each side to get:

-7x = 10

The number of selfies deleted by Alex is 63.

In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.

The solution of an equation is the set of all values that, when substituted for unknowns, make an equation true.

Given that, last week, Alex took 90 selfies and Vic took 75 selfies.

Let the number of selfies deleted by Vic be s.

Alex deleted three times as many selfies as Vic.

So, the number of selfies deleted by Alex =3s

Alex has half as many selfies as Vic.

Now, 90-3s = 1/2 (75-s)

180-6s=75-s

5s=105

s=21

The number of selfies deleted by Alex =3s

= 63

Therefore, the number of selfies deleted by Alex is 63.

Log x is defined for all positive real numbers (x>0). Exponential functions increase exponentially (x^y) and logarithmic functions decrease logarithmically (log x).

Log x is defined as the inverse of the exponential function. Exponential functions increase exponentially (x^y) and logarithmic functions decrease logarithmically (log x). The logarithm of a number is the exponent to which another fixed number must be raised to produce that number. Log x is defined for all positive real numbers (x>0). This means that any number that is greater than 0 can have a logarithm associated with it. For example, log 10 = 1 because 10^1 is equal to 10. The logarithm of a number can also be expressed in terms of other logarithms. For example, log 10 = log 10^2 = 2 log 10. Log x can also be used to solve equations and find the value of unknown variables.

A prime number is a whole number greater than 1 which only divisible by 1 and itself. Example of prime numbers are 2, 3, 5, 7, ...

We want to form 4 two-digit numbers from, 1, 2, 3, 4, 5, 6, 7, 8.

Recall that: other than 2, all even numbers are not prime since they are divisible by 2. Hence, from those numbers, we look at which odd two-digit numbers are prime.

We have four odd numbers in the list that can construct two-digit odd numbers: 1, 3, 5, 7.

However, two-digit numbers with 5 as its second digit is not prime since they are exactly divisible by 5.

Therefore, now we only have 3 numbers (1, 3, 7) that can construct two-digit odd numbers. Hence, the largest number of primes that could possibly formed is 3 numbers.

In most cases, the product of a monomial and a binomial is a trinomial.

A monomial is an algebraic expression that is a single term, such as 2x or 5y^3. A binomial is an algebraic expression that is a sum or difference of two terms, such as x+y or 2x-3y. When a monomial is multiplied by a binomial, the result is an expression with three terms, which is called a trinomial.

For example, when we multiply the monomial 2x with the binomial x+y, we get:

(2x)(x+y) = 2x^2 + 2xy

This is a trinomial because it has three terms: 2x^2, 2xy and the constant term is missing.

It's worth noticing that, this is a general rule but not always true, there are some cases when the product of a monomial and a binomial is a binomial, like when the monomial has a factor that cancels out one of the terms in the binomial.

The amount of money Bilquis have more than Sophie when compounded continuously is given by the equation A = $ 42

Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.

The formula for calculating Compound Interest is

A = P ( 1 + r/n )ⁿᵇ

where A = Final Amount

P = Principal

r = rate of interest

n = number of times interest is applied

b = number of time periods elapsed

Given data ,

Let the compound interest amount of Bilquis be represented as B

Let the compound interest amount of Sophie be represented as S

The amount of money invested by Bilquis and Sophie is = $ 6,900

The rate of interest of Bilquis = 5 1/8 = 5.125 %

The rate of interest of Sophie = 4 3/4 = 4.75 %

The time period b = 18 months = 1.5 years

So , the amount after compound interest A = P ( 1 + r/n )ⁿᵇ

Substituting the values in the equation , we get

The amount with Bilquis after 18 months B = Pe^rt ( compounded continuously )

The amount with Bilquis after 18 months B = 6900 ( 2.71828 )^(0.05125)(1.5 )

On simplifying the equation , we get

The amount with Bilquis after 18 months B = $ 7451.36

And ,

The amount with Sophie after 18 months S = Pe^rt ( compounded continuously )

The amount with Sophie after 18 months S = 6900( 2.71828 )^(0.0475)(1.5 )

On simplifying the equation , we get

The amount with Sophie after 18 months S = $ 7409.56

So , the difference in amount is A = amount with Bilquis after 18 months B - amount with Sophie after 18 months S

On simplifying the equation , we get

The difference in amount is A = 7451.36 - 7409.56

The difference in amount is A = $ 41.8

So , The difference in amount is A = $ 42

Hence , Bilquis had $ 42 more than Sophie

g(x) = ([tex]\sqrt{x-3}[/tex])/3 + 5

Step-by-step explanation:

f(x) = [tex]\sqrt{x}[/tex] + 5

[tex]\sqrt{x}[/tex] + 5  ==> 1/3 * [tex]\sqrt{x}[/tex] + 5  ==> vertical shrink is when the function's y-coordinates shrink from the y-intercept (5 is the y-int) by a factor of 1/3

[tex]\sqrt{x}[/tex]/3 + 5 ==>( [tex]\sqrt{x-3}[/tex])/3 + 5 ==> in order to translate the graph 3 units to the right, subtract x by 3 since x is being affected when the graph moves left/right. In addition, x now has to be 3 units greater in order for the function to have the same value:

[tex]\sqrt{4-3}[/tex] = [tex]\sqrt{1}[/tex]

4 > 1 and 4 = 1 + 3

Hence, g(x) = ([tex]\sqrt{x-3}[/tex])/3 + 5

To find the value of f(-2) on a graph, you would locate the point (-2, y) on the graph, where y is the value of the function at x = -2. The value of y is the y-coordinate of the point on the graph.

In a cartesian coordinate system, the x-axis and y-axis are perpendicular to each other. The x-axis is the horizontal axis and the y-axis is the vertical axis. When a function is graphed, the x-coordinate is input into the function and the y-coordinate is the output of the function. So, when you are trying to find the value of f(-2) on a graph, you are looking for the y-coordinate of the point where x = -2. To find this point, you would move horizontally along the x-axis until you reach the value of -2. Then, you would move vertically from that point until you reach the point on the graph. The y-coordinate of that point is the value of f(-2)

where p is the probability that each component functions (in this case, 0.9) and n is the total number of components.

To find the smallest value of n that satisfies the condition P(function) ≥ 0.9, we can rearrange the formula to:
