Write an equation of the line below.<br> (0,-2) (8,-4)

olga_2 [115]

Answer:

Step-by-step explanation:

Equation of a line is y = mx + c

where

m is the slope

c is the y intercept

First of all to find the equation of the line we must first find the slope.

The slope of the line using points

(0,-2) (8,-4) is

Now using one of the points and the slope we can find the equation of the line.

Equation of the line using point (0 , - 2) and slope - 1/4 is

We have the final answer as

Hope this helps you

What are irrational numbers?<br> Are they related to Rational numbers?

emmainna [20.7K]

An irrational number is a number that cannot be expressed in a fraction form while a rational number can.

an example of an irrational numbers are repeating numbers such as 0.77777... and examples of rational numbers are decimals such as 0.20, whole numbers such as 5, and fractions like 2/3

hope this helps a bit.

Explain how the expression 8.3√2+7.9√2 can be simplified using the distributive property.

IceJOKER [234]

Answer:

$\sqrt{2}(16.2)$

Step-by-step explanation:

The distributive property says that the answer of multiplying two numbers is the same as multiplying the first number by the sum or subtraction of two numbers that result in the second number.

What we have to do is to simpligy the ecuation, this mean, making it shorter.

First we take out the common term of the ecuation: $\sqrt{2}$ .

By distributive property $8.3\sqrt{2} +7.9\sqrt{2} =\sqrt{2}(8.3+7.9)$

then $\sqrt{2} (16.2)$ .

16. How many liters of a 60% alcohol solution must be added to 60 liters of a 30% alcohol

Nezavi [6.7K]

Step-by-step explanation:

Step 1: Question statement and Inferences

Let x liters of the 60% solution be added.

So, amount of Alcohol in this solution = 60% of x = 0.6x L

Now, let us consider the 40% solution.

The total volume of this solution is 50 L

So, amount of Alcohol in this solution = 40% of 50

Step 2: Finding required values

When x L of 60% solution are mixed with 50 L of the 40% solution, the total volume of the resultant solution will be (50+x) L

By the Law of Conservation of Mass,

Amount of alcohol in the input solutions = Amount of alcohol in the final solution

=> Amount of alcohol in the final solution = 20 + 0.6x

So, concentration of Alcohol in the final solution

Step 3: Calculating the final answer

It is given that the concentration of alcohol in the final solution is 50%
