Abby can buy individual songs for $1.00 to download, or she can
Taya2010 [7]

The solution to the inequalities x + 8y ≤ 50, x ≤ 30, y > 2 is the darker region shown on the graph.

<h3>What is an equation?</h3>

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

Let x represent the number of individual songs and y represent the number of albums, hence:

x + 8y ≤ 50   (1)

x ≤ 30    (2)

y > 2   (3)

The solution to the inequalities x + 8y ≤ 50, x ≤ 30, y > 2 is the darker region shown on the graph.

Solve by graphing.
melisa1 [442]

Given:

The given system of equations is:

2x+y=1

x-2y=8

To find:

The solution to this system of equations by graphing.

Solution:

We have,

2x+y=1

x-2y=8

The table of values for first equation is:

x       y

0      1

1      -1

Plot the points (0,1) and (1,-1) on a coordinate plane and connect them a straight line.

The table of values for second equation is:

x       y

0      -4

2      -3

Plot the points (0,-4) and (2,-3) on a coordinate plane and connect them a straight line.

The graphs of given equations are shown in the below figure.

From the below figure, it is clear that the lines intersect each other at point (2,-3). So, the solution of the given system of equations is (2,-3).

Therefore, the solution to this system of equations is:

x-coordinate: 2

y-coordinate: -3

Sterre charges $35 to file tax returns, but files for free if she only needs the easiest form. Then she donates $2 to clean wate
borishaifa [10]

We have been given that Sterre charges $35 to file tax returns, but files for free if she only needs the easiest form. Also, she donates $2 to clean water projects per tax return she files.

Further we know that Sterre charged $7,245 and made a donation of $1,242 this year for the tax returns she filed.

Let x be the number of free income tax returns and y be the number of $35 income tax returns.

Therefore, we can set up:

0\times x+35\times y=7245\Rightarrow 35y=7245\Rightarrow y=\frac{7245}{35}=207

Since she donates $2 for each return that she files, therefore, we can set up:

2(x+y)=1242\Rightarrow x+y=621\Rightarrow x+207=621\Rightarrow x=414

Therefore,

Sterre filed 414 tax returns for free and filed 207 tax returns for $35.

Convert the following in standard form : -4x=4y-52
goldenfox [79]
The standard form of any linear equation with two variables is ax+by=c, where a, b, and c are constants. To convert this equation to standard form, simply subtract 4y from both sides to get

-4x-4y=-52

We could leave it in this form, though, in this case, it might be better at if we multiplied both sides by -1 to get

4x+4y=52

Give an example of a real number that is irrantional
dsp73

First let's see what does irrational mean.

An irrational number is any number that cannot be written as a fraction of whole numbers. The number pi and square roots of non-perfect squares are examples of irrational numbers. ... , however, is not a perfect square, and its square root, therefore, is irrational.

<h2>Now, the answer to your question. </h2>

√2 is an irrational number since it cannot be written as a ratio of two integers.

look at the picture below to see why√2 is an irrational number
