What is the purpose of simultaneous equations?

1 answer:

5 0

Answer:

a set of two or more equations, each containing two or more variables whose values can simultaneously satisfy both or all the equations in the set, the number of variables being equal to or less than the number of equations in the set.

Step-by-step explanation:

It works because of two properties of equations: Multiplying (or dividing) the expression on each side by the same number does not alter the equation. Adding two equations produces another valid equation: e.g. 2x = x + 10 (x = 10) and x − 3 = 7 (x also = 10).

Consider the equation

sergij07 [2.7K]

Answer:

B. (-6, -9)

D. (12, 3)

Step-by-step explanation:

y=mx+b is the format for this problem.

2/3 is m and -5 is b

The b is the y-intercept which is the point where the line crosses from one side of the graph to the other horizontally. You can see at -5, that is where that happens.

Then, to find the second point, you would move the -5 up 2 and right 3 points because the slope is 2/3.

You can then look at another point of the graph to find (-6, -9)
