Answer:

Step-by-step explanation:

Commutative property of addition:  The order in which you add these fractions together doesn't matter.

I would combine 3/5 and 2/5 first, as that readily results in 5/5, or just 1.

Then we have 1 1/4, or 1.25, or 5/4 as the final answer.

Which table shows the reflection of f(x) across the y-axis? HELP ASAP!!
tangare [24]

Answer:

The first one

Step-by-step explanation:

When you do a reflection across the y-axis, it is like a mirror. And if you have a generic point (x, y) the new point will be (-x, y).

In the table you have 4 points:

(x,y)

(-3,9)

(0,0)

(2,4)

(5,25)

The new points will be:

(3,9)

(0,0)

(-2,4)

(-5,25)

Expand.<br> If necessary, combine like terms.<br> (3 + 4x) (3 - 4x)
shepuryov [24]
  • (3 + 4x) (3 - 4x)

We know the algebraic identity: (a - b)(a + b) = a^2 + b^2. Therefore, we should square 3 and 4x.

  • = (3)^2 - (4x)^2
  • 9 - 16x^2

<u>Answer</u><u>:</u>

<u>9</u><u> </u><u>-</u><u> </u><u>1</u><u>6</u><u>x</u><u>^</u><u>2</u>
