What is the value of q?

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]

Step-by-step explanation:

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:

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:

1: The car is moving at a constant speed

2: The car is stopped

3: The car is decreasing in speed

Step-by-step explanation:

1. It's moving at a constant speed as it's moving up in a straight line

2. It's stopped because the line is flat

3. It's slowing down as the slope is getting smaller

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).

20%=cows 0.4(40%)=goat 40%=sheep

if 40%sheep=40 sheeps

20% cow=x

20%×40=40%×x

8=40%x

x=8/40%

x=20

..so there are 20 cows

sorry...not sure

Answer:

There are 20cows

Step-by-step explanation:

20%=0.2 of cows

0.4=goats

1-(0.2+0.4)=0.4 are sheep

Using ratio and proportion,

0.2/0.4×40=20

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]

[tex]P=464.58[/tex]

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

= 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.

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
