Answer:
x = -2
Step-by-step explanation:
x^2 - 3x - 10 when we factorize equals
(x + 2) (x - 5)
3x^2 + 5x - 2 when we factorize equals
(3x - 1) (x + 2)
x + 2 is the common term and when we put the 2 on the other side of the equation we get x = -2
Explanation:
Remember the following properties of real numbers:
Reflexive property:
This property states that a number is always equal to itself.
This property is different from the equivalent equations property. In fact, two equations that have the same solution are called equivalent equations,
Division property of equality:
This property states that when we divide both sides of an equation by the same non-zero number, the two sides remain equal.
Substitution property of equality:
This property states that if x = y, then x can be substituted in for y in any equation.
We can conclude that the correct answer is:
Answer:Drop Down 1: reflexive property
Drop Down 2: division property of equality.
Drop Down 3: substitution
Answer:
The coordinate stayed the same
Step-by-step explanation:
because when you reflect on the x-axis, the x-axis stays the same while the y-axis gets flipped. in this case, the coordinate is on the y-axis, or the y-axis is 0, and you can't flip 0 to get an opposite. the opposite of 0 is 0, so he coordinate stayed the same.
