How can you determine if a point is a solution to a system of linear equations?
Please Help!

Answers

Answer:

You can substitute the x value of coordinate (x,y) in the equation. If the outcome = the y value in the coordinate (x,y), then you have determined it to be on the system of linear equations.

Step-by-step explanation:

Point P has a coordinates: ( Px , Py ).

You can choose which value is easy to substitute. Eighter start with the Py or you could start with the Px. It could save you time if you pick the right one for the job.

If you want to verify if any point is valid in any (linear) equation(s), you can:

a) substitute the x value of coordinate (x,y) in the equation, and if the outcome has the same value as y in the coordinate (x,y), then that point is a valid solution of the (linear) equation.

b) substitute the y value of coordinate (x,y) in the equation, and if the outcome has the same value as x in the coordinate (x,y), then that point is a valid solution of the (linear) equation.

Answer:

You can substitute the x value into the equation if the answer for y is the same for the y coordinate you will have your answer.

To convert 0.9 to a fraction, Lauren wrote n=0.9 as her first step. For her second step, what should she multiply both sides of that equation by? A) 10
B) 100
C) 1000
d) 10,000

Answers

The number should be multiply is 10.

What is multiplication?

In math, to multiply means to add equal groups. When we multiply, the number of things in the group increases. The twofactors and the product are parts of a multiplication problem.

Given:

n=0.9

Now, there is one number behind decimal point.

So, we have to multiply it by 10 to convert it into fraction from decimal.

Thus,

10n = 0.9*10

10n = 9

n = 9/10

Hence, the number must be multiplied is 10
