Answer:

The answer is x>2

Step-by-step explanation:

2x + 3 > 7

-3           -3

2x > 4

/2    /2

x>2

Answer:

x > 2

Step-by-step explanation:

Given

2x + 3 > 7 ( subtract 3 from both sides )

2x > 4 ( divide both sides by 2 )

x > 2

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.

Step-by-step explanation:

answer 2. should be right

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:

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

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 Explanation:

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]

Answer:

The cost when the two companies charge the same is $7,703.

Step-by-step explanation:

Let 'x' represent the number of tons.

For x tons the first company will charge:

5297 + 200.50x

For x tons the second company will charge:

6500 + 100.25x

We want to find x so that both companies charge the same, that is:

5297 + 200.50x = 6500 + 100.25x

x = 12 tons

For 12 tons both companies will charge the same.

The cost charged for 12 tones is:

5297 + 200.50*12 = $7,703

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:
