Answer:

y=x^2

Step-by-step explanation:

The true equation about the logarithmic equation [tex]\log_xy = 2[/tex] is [tex]y = x^2\\[/tex]

The logarithmic equation is given as:

[tex]\log_xy = 2[/tex]

Apply the change of form logarithm rule.

This rule would convert the logarithmic equation to an exponential equation.

So, we have:

[tex]y = x^2\\[/tex]

Hence, the true equation about [tex]\log_xy = 2[/tex] is [tex]y = x^2\\[/tex]

Step-by-step explanation:

Given the wholesale price of pillow is $6.50

Price in department store is 70% more than whole sale =1.7 times the wholesale

Price in department store =1.7*6.5=$11.05

x > - 1

x ∈ ( - 1 ; + oo)

Hi there !

x + 5 > 4

x > 4 - 5

x > - 1

x ∈ ( - 1 ; + oo)

Good luck !

Solution:

To solve this problem, we will use PRT/100.

Where:

1. Converting the number of months into years.

[tex]\bullet \ \ 1 \ \text{year} = 12 \ \text{months}[/tex]

[tex]\bullet \ \ \rightarrow \text{x years = 12x months = 18 months}[/tex]

[tex]\bullet \ \ \rightarrow \frac{12x}{12} = \frac{18}{12}[/tex]

[tex]\bullet \ \ \rightarrow x = 1.5 \ \text{years}[/tex]

2. Using PRT/100:

[tex]\bullet \ \ \rightarrow \dfrac{P \times R \times T}{100}[/tex]

[tex]\bullet \ \ \rightarrow \dfrac{1900 \times 5.9 \times 1.5}{100}[/tex]

[tex]\bullet \ \ \rightarrow19 \times 5.9 \times 1.5}[/tex]

[tex]\bullet \ \ \rightarrow \boxed{\$168.15}[/tex]

Thus, the interest will be [tex]\bold{\$168.15}[/tex].

Answer:

36/45 and 35/45

Step-by-step explanation:

5 and 9's least common denominator is 45 and to get to that you need to multiply both top and bottom of how to get to 45. How I got to 45 the easiest way is to keep multiplying both numbers until the reach the same product. In this case for 4/5, you multiply it by 9 for top and bottom. And for 7/9, it would be multiplying by 5 for top and bottom which will get you both of the answers. Hopefully this answers your question.

Answer:

f(g(x)) = 7x + 27

Step-by-step explanation:

We have, f(x) = 7x+13 and g(x) = x+2.

So, the function f(g(x)) is obtained by substituting the function g(x) = x+2 in f(x) = 7x+13,

i.e. f(g(x)) = f(x+2)

i.e. f(g(x)) = 7 × (x+2) + 13

i.e. f(g(x)) = 7x + 14 + 13

i.e. f(g(x)) = 7x + 27

Thus, f(g(x)) = 7x + 27

Answer:

65°

Step-by-step explanation:

Sum of interior angles of a triangle = 180°

⇒ m∠EAB = 180 - 90 - 70 = 20°

⇒ m∠DAG = 90 - 45 - 20 = 25°

⇒ m∠AGD = 180 - 90 - 25 = 65°

ΔADG ≅ ΔAFG

⇒ m∠AGD = m∠AGF = 65°

ΔABE ≅ ΔAFE

⇒ m∠AEB = m∠AEF = 70°

Answer:

Step-by-step explanation:

(a - b)² = a² - 2ab + b²

We have

w² - 2w = w² - 2(w)(1)

We must add 1²

w² - 2(w)(1) + 1² = (w - 1)²

The answer is ,w² - 2(w)(1) + 1² = w² - 2w + 1 = (w - 1)², the perfect square.

A perfect square is a number, from a given number system, that can be expressed as the square of a number from the same number system. Examples of Numbers that are Perfect Squares. 25 is a perfect square. 25 is a natural number, and since there is another natural number 5, such that 52 = 25, 25 is a perfect square.

Here, we have,

(a - b)² = a² - 2ab + b²

We have

w² - 2w = w² - 2(w)(1)

We must add 1²

w² - 2(w)(1) + 1² = (w - 1)²

Hence, The answer is ,w² - 2(w)(1) + 1² = w² - 2w + 1 = (w - 1)², the perfect square.
