Which property of equality would be used to solve the equation -3x = 252?

The Division Property of Equality would be used here.

It states that both sides of an equation can be divided by a number not equal to zero and still be equivalent. Both sides of -3x = 252 can be divided by -3 and still be equivalent.

By the way,  x = -84!

Answer:

a^4+3a^2-3b^2

Step-by-step explanation:

\hookrightarrow \: (2 {a}^{2}  - b)(3 {a}^{2}  + 3b) \\  \hookrightarrow \:2 {a}^{2} (3 {a}^{2}  + 3b) - b(3 {a}^{2}  + 3b) \\  \hookrightarrow \:6 {a}^{4}  + 6 {a}^{2} b - 3 {a}^{2} b - 3 {b}^{2} \\   \hookrightarrow \:{a}^{4}  + 3 {a}^{2} b- 3 {b}^{2}

How can properties of operations help to generate equivalent expressions that can be used in solving problems ?
svet-max [94.6K]
I’m not the best at math, but ⬇️

For example, apply the distributive property to the expression 3(2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y

A) x = -2<br> B) y =2<br> C) y= -2
LenKa [72]

Answer:

Step-by-step explanation:

This is a positive parabola so it opens upwards. The equation for the directrix of this parabola is y = k - p. k is the second number in the vertex of the parabola which is (0, 0), but we need to solve for p.

The form that the parabola is currently in is

y=a(x-h)^2+k so that means that a=\frac{1}{8}. We can use that to solve for p in the formula

p=\frac{1}{4a} so

p=\frac{1}{4(\frac{1}{8}) } which simplifies to

p=\frac{1}{\frac{1}{2} } which gives us that

p = 2. Now to find the directrix:

y = k - p becomes

y = 0 - 2 so

y = -2, choice A.
