Answer:
The property that defines a perfect square trinomial is that the second term is 2 times the product between the squares of each square term.
Step-by-step explanation:
- Option A is true, <u>but is not a property,</u> is a condition of the definition of a perfect square trinomial
- Option B is true, <u>but is neither a property</u>, is also a condition of the definition of a perfect square trinomial.
- Option C is true, and is a property of the trinomial, because this property, is the one which allows to apply the defined simplification for a perfect square trinomial: [tex]a^2±2ab+b^2=(a±b)^2[tex/]
Answer:
$375
Step-by-step explanation:
hope this helps! :)
The first step to solving this is to multiply both sides of the equation by 3
8 + 10y = 9y - 12
now move the variable to the left side and change its sign
8 + 10y - 9y = -12
move the constant to the right side and change its sign
10y - 9y = -12 - 8
collect the like terms for y
y = -12 - 8 (it equals 1 when you subtract 10 from 9 which is the same is simply saying "y")
calculate the difference on the other side of the equals sign
y = -20
this means that the correct answer to your question is -20.

Answer:
<em><u>x=2, y=4</u></em> (as a point,) (2, 4) (last part is unnecessary unless you are graphing)
Step-by-step explanation:
Use substitution.
Substitute y for 2x.
Since y=2x, you can plug 2x into the place where y goes...
Instead of y=-1/2x+5
2x=-1/2x+5....Now solve
2.5x=5 (Sorry my computer cannot type fractions very clearly)
/2.5 /2.5 (dividing by 2.5 on both sides)
<u><em>x=2</em></u>
Now just plug x into any of the equations to find y (preferably the easier one).
y=2x becomes
y=2*(2)
=4
<em><u>y=4</u></em>
