Answer

The answer is most likely 2 (or C).

Why?

The top of the question simplified into number is 2(5 + 3), which equals 16.

The bottom is (3 +5)1, which equals 8.

Now divide 16/8, which equals 2, and there's your answer.

(Hope this helps you! ^^)

Answer:

2

Step-by-step explanation:

First, substitute the x’s and y’s:

2(5+3)/(3+5)1

since the one doesn’t make a difference, we don’t need to write it in.

2(5+3)/(3+5)

next, solve the parenthesis first:

5+3=8

3+5=8

so,

2(8)/8

Now since there are two 8s on each side, they cancel eachother out since if you cross them over and change the sign,

2/8/8

it equals 1.

so, you are left with 2.

Reflect (5,-4) over the y-axis. Then translate the result to the right 2 units. What are the coordinates of the final point?
lesya692 [45]

Answer:

(-3,-4)

Step-by-step explanation:

When reflecting across the y-axis, you will mirror the coordinates across the y-axis. This means (5,-4) will turn into (-5,-4) because mirroring it across the y-axis will only change the x coordinate. Then, to translate it to the right, you move to the right two times to give you (-3,-4). The y-coordinate will never change in this situation because you are only reflecting and moving left and right.

Please help ASAP!!!!!!
Schach [20]

Answer:

see explanation

Step-by-step explanation:

(f + g)(x) = f(x) + g(x), so

f(x) + g(x)

= x² + 5x + 6 + x + 3 ← collect like terms

= x² + 6x + 9

-------------------------------------------------

(f - g)(x) = (f(x) - g(x), so

f(x) - g(x)

= x² + 5x + 6 - (x + 3) ← distribute by - 1

= x² + 5x + 6 - x - 3 ← collect like terms

= x² + 4x + 3

---------------------------------------------------

(f • g)(x)

= f(x) × g(x)

= (x² + 5x + 6)(x + 3)

Each term in the second factor is multiplied by each term in the first factor, that is

x²(x + 3) + 5x(x + 3) + 6(x + 3)  ← distribute parenthesis

= x³ + 3x² + 5x² + 15x + 6x + 18 ← collect like terms

= x³ + 8x² + 21x + 18

---------------------------------------------------------------

(\frac{f}{g} )(x)

= \frac{f(x)}{g(x)}

= \frac{x^2+5x+6}{x+3} ← factor the numerator

= \frac{(x+2)(x+3)}{x+3} ← cancel common factor (x + 3) on numerator/ denominator

= x + 2

Solving quadratic equations by factoring <br> m(m-3)=0
KatRina [158]
Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.

We can either have m = 0 or m - 3 = 0
Hence, m is either 0 or 3
