How can you analyze connections between linear equations and use them to solve problems

Mathematics

Alexeev081 [22]3 years ago

Answer:

Step-by-step explanation:

One of the more obvious "connections" between linear equations is the presence of the same two variables (e. g., x and y) in these equations.

Assuming that your two equations are distinct (neither is merely a multiple of the other), we can use the "elimination by addition and subtraction" method to eliminate one variable, leaving us with an equation in one variable, solve this 1-variable (e. g., in x) equation, and then use the resulting value in the other equation to find the value of the other variable (e. g., y).  By doing this we find a unique solution (a, b) that satisfies both original equations.  Not only that, but also this solution (a, b) will also satisfy both of the original linear equations.

I urge you to think about what you mean by "analyze connections."

You insurance policy on your car costs $600 a year. If you total your vehicle, you insurance company will pay $25,000 towards a
vladimir2022 [97]

Answer:

Your annual expected value is -$550.

Step-by-step explanation:

0.002 probability that you will total your car.

If you total your car, you pay the insurance of $600, but you get the $25,000 insurance. So in total, the net value will be $24,400.

1-0.002 = 0.998 probability that you will not total your car.

In this case, you lose $600.

What is your annual expected value?

Multiply each net value by it's probability.

E = 0.002*24400 - 0.998*600 = -550

Your annual expected value is -$550.

A number which precedes a variable and that can be expressed in the form a/b (where a and b are integers) is called a ___ coeffi
Vadim26 [7]

The answer is: Rational coefficient.

The explanation for this answer is shown below:

1. By definition, a rational number has the form \frac{a}{b} where a is the numerator and b is the denominator. The numerator and the denominator are integers.

2. By definition, integers numbers includes positive numbers, negative numbers and zero.

3. Keeping the information above on mind, you can conclude that the answer is: Rational coefficient.

4. For example:

\frac{1}{3}x

\frac{1}{3} is a rational coefficient.

Can u help me answer this I’m so stuck
Slav-nsk [51]

Answer:

I learned a great formula for repeating decimals.

OK! Let's get started. For each decimal spot that is recurring, it is put over a 9, rather than a 10.

In your case, 0.142 would be 142 over 3 9s.

142/999 cannot be simplified.

Therefore, 142/999 is our answer.

Since the repentant is over only one digit, we have to solve another way.

We can represent it as "x"

10x = 5.66.... - x = 0.56.....=5.1

9x = 51/10

51/10/9 = 51/90 = 17/30 as our answer.

We can solve this next one the same way:

100x = 3.44444 - x  = 3.41

999x = 341/100

341/100/999 = 31/900 as our answer.

Now! 1.52 can be solved the same way.

In doing so, we achieve the answer 151/99 as our answer

This one can be done the same way as well. I'll give you the answer, but next time try to solve it for yourself!

179/495 is our answer.

Now, you asked for 0.004 as a fraction.

That is equivalent to 4/999 as our answer.

Note: This is because each 0 can be counted as a 9, increasing in order. (i.e., over 100 is over 99 over 1000 is over 999 over 10 9)
