Answer:

length is between 1 inch and 2 inches

Step-by-step explanation:

Given that :

Length of Mp3 = 1 3/4 inches

Converting to decimal :

7/4 inches = 1.75 inches

1.75 lies in between 1 inch and 2 inches ;

1.75 > 1 and 1.75 < 2

Hence,

1 < 1.75 < 2

Hence, length is between 1 inch and 2 inches

Step-by-step explanation:

Answer:

y = 2x + 2

-4 = 2(-3) + 2

-4 = -6 + 2

-4 = -4

y = x - 1

-4 = -3 - 1

-4 = -4

It is the solution

Step-by-step explanation:

Answer: Yes, it is the solution to the system.

=========================================================

Explanation:

The point (-3,-4) means that x = -3 and y = -4 pair up together.

Let's plug those values into the first equation and simplify

y = 2x+2

-4 = 2(-3)+2 .... replace x with -3; replace y with -4

-4 = -6+2

-4 = -4 ... we get a true equation

Let's repeat for the other equation as well

y = x-1

-4 = -3-1

-4 = -4 .... this is also true

Since both equations are true, this means (-3,-4) is the solution to the system. The two lines intersect at (-3,-4).

Here, we want to know when a parallelogram is a rectangle

There are some properties to be satisfied by the parallelogram to know it is a rectangle

If the parallelogram in question has diagonals that are equal in length, meaning that the by are congruent, then we can say is it a rectangle

Also, the parallelogram must contain four right angles for use to say it is a rectangle

Answer:

We conclude that:

[tex]3\ln \left(m\right)+4\ln \left(n\right)=\ln \left(m^3n^4\right)[/tex]

Step-by-step explanation:

Given the expression

[tex]3\ln \left(m\right)+4\ln \left(n\right)[/tex]

Apply log rule:  

So the expression becomes

[tex]3ln\:m\:+\:4ln\:n=\ln \:\left(m^3\right)+\ln \:\left(n^4\right)[/tex]

Apply log rule:

[tex]\log _c\left(a\right)+\log _c\left(b\right)=\log _c\left(ab\right)[/tex]

so the expression becomes

                           [tex]=\ln \left(m^3n^4\right)[/tex]

Therefore, we conclude that:

[tex]3\ln \left(m\right)+4\ln \left(n\right)=\ln \left(m^3n^4\right)[/tex]

Answer:

Step-by-step explanation:

The graph of y= -3/2x + 1 is given in attachment with slope -3/2.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given line is  y= -3/2x + 1

slope is -3/2

We have to find few values of x and y.

When x=0

y=1

When x=1

y=-1/2

When x=2

y=-2

Hence, the graph of y= -3/2x + 1 is given in attachment with slope -3/2.

Answer:

Juan

Step-by-step explanation:

The number of pages that Ana, Hillary, Roger, and Juan can read in a day is shown below:

For Ana

Ana read 15% of her 46-page book.

= 15% × 46 pages

= 6.9 pages

For Hillary

Hillary read 11% of her 72-page book.

= 11% × 72 pages

= 7.92 pages

For Roger

Roger read 12% of his 68-page book.

= 12% × 68 pages

= 8.16 pages

For Juan

Juan read 14% of his 69-page book.

= 14% × 69 pages

= 9.66 pages

The person who can read greatest number of pages in a day also means the person who read the highest number of pages in a day.

From the calculation above, that person in JUAN because she can read 9.66 pages of her book in one day.

Answer:

The solution to the equation is as follows;

[tex]x = \frac{5}{19} ,\ and \ y= \frac{2}{19}[/tex]

Step-by-step explanation:

Given;

5x - 3y = 1

3x + 2y = 1

Solving both equation simultaneously;

2:   10x  - 6y = 2

3:   9x   + 6y = 3

--------------------------

        19x   + 0 = 5

            x = 5/19

substitute the value of x in any of the equations above and solve for y;

5x - 3y = 1

5 (5/19) - 3y = 1

25/19 -3y = 1

[tex]3y = \frac{25}{19} -1\\\\3y = \frac{25-19}{19} \\\\3y = \frac{6}{19} \\\\y = \frac{2}{19}[/tex]

Answer:

-5=5x+5y when you divide it by 5 I don't understand how the equation then becomes x=-1-y when you are dividing by a positive 5

Step-by-step explanation:

Example Question #1. If 7x + y = 25 and 6x + y = 23, what is the value of x? You could also solve one equation for y and substitute that value in for y in the other equation: 6x + y = 23 → y = 23 – 6x.

The amount of money Brooklyn need to invest, for the value of the account to reach $530 in 7 years is $500

An equation is an expression that shows the relationship between two or more numbers and variables.

Let P represent the amount of money that Brooklyn should invest, hence:

Since the interest is 1.9% (0.019) in 7 years, therefore:

[tex]$530=P(1 + \frac{0.019}{1} )^{1*7}\\\\\\[/tex]
