When a rational and an irrational number are added, is the sum rational or irrational? Explain.
Ilya [14]
Sum of an irrational number and a rational number is always irrational. Take for example 1/2 + \pi. Clearly, 1/2 is rational and its decimal expansion is equal to 0.5, while \pi is irrational and has a non-repeating, non-terminating decimal expansion. When you add the two, you are obviously going to get a non-repeating, non-terminating decimal expansion, hence the sum is irrational.

How many solutions are there to the system of equations?
hichkok12 [17]

Answer: The system of equations has NO SOLUTION.

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

y=mx+b

Where "m" is the slope and "b" is the y-intercept.

Given the following system of equations:

\left \{ {{4x-5y=5} \atop {-0.08x+0.10y=0.10}} \right.

Write the first equation and solve for "y" in order to express it in Slope-Intercept form:

4x-5y=5\\\\-5y=-4x+5\\\\y=\frac{-4x}{-5}+\frac{5}{-5}\\\\y=0.8x-1

You can identify that:

m=0.8\\b=-1

Apply the same procedure with the second equation. Then:

-0.08x+0.10y=0.10\\\\0.10y=0.08x+0.10\\\\y=\frac{0.08x}{0.10} +\frac{0.10}{0.10}\\\\y=0.8x+1

You can identify that:

m=0.8\\b=1

The slopes of both lines are equal, therefore  the lines are parallel and the system has NO SOLUTION.

Simply the variable expression below as much as possible. <br><br> 7x + (5.6) z
marta [7]

Answer:

7x + 5.6z

Step-by-step explanation:

To simplify any expression we use PEMDA ( order of operation)

Parenthesis

Exponents

Multiplication and division

Addition and subtraction

7x + (5.6) z

Here we have 5.6 inside the parenthesis

We multiply 5.6 with z

so it becomes 5.6z

7x + 5.6 z

Both terms 7x and 5.6z have different variable so they are not like terms

We cannot combine unlike terms, so we leave as it is

7x + 5.6z
