What is the solution to the system of equations?

In this case the two equations<span> describe lines that intersect at one particular point. Clearly this point is on both lines, and therefore its coordinates (x, y) will satisfy the </span>equation<span> of either line. Thus the pair (x, y) is the one and only </span>solution to the system of equations<span>.</span>

X^2-3x=0 zero product property

stellarik [79]

Answer:

x1 = 0

x2 = 3

Step-by-step explanation:

${x}^{2} - 3x = 0$

If that's the right equation we can now just simplify it a bit.

$x \times x - 3 \times x = 0$

Cause now it becomes obvious that we can break out x and make it into a parenthesis:

$x(x - 3) = 0$

And now there's two possibilities for what x could be. Either, x is 0:

$0(0 - 3) = 0$

Or, the parenthesis is 0, which means that x is 3 (because 3-3=0) :

$x(3 - 3) = 0$

So x has two answers:

x1 = 0

x2 = 3

how to find the percent when they already give you the answer. For example: _% of 40=15 what would the answer be and how do you

bulgar [2K]

So the question is what percent of 40 is 15
Let's write proportion
100%-40
X% - 15
X=15·100:40=1500:40=37,5%

Answer: 37,5% of 40 is 15.
