11) Endpoint: (0,4), midpoint (-10, -3)<br> Find the endpoint?

earnstyle [38]

Answer:

(-20,-10)

Step-by-step explanation:

$( - 10 \: \: - 3) = ( \frac{0 + x}{2} \: \: \frac{4 + y}{2} )$

Solve for.x coordinate

$- 10 = \frac{0 + x}{2} \\ - 20 = 0 + x \\ x = - 20$

solve for y coordinate

$- 3 = \frac{4 + y}{2} \\ - 6 = 4 + y \\ - 10 = y$

Add (3x + 9 / 2x + 6) + (8x + 12 / x^2 + 6x + 9)

jenyasd209 [6]

Answer:

$\dfrac{3x^2+34x+51}{2x^2+12x+18}$

Step-by-step explanation:

$\dfrac{3x+9}{2x+6}+\dfrac{8x+12}{x^2+6x+9}= \\\\\\\dfrac{3(x+3)}{2(x+3)}+\dfrac{8x+12}{(x+3)(x+3)}$

To add these two fractions, you need to make the denominators equal:

$\dfrac{3(x+3)(x+3)}{2(x+3)(x+3)}+\dfrac{16x+24}{2(x+3)(x+3)}= \\\\\\\dfrac{(3x^2+18x+27)+(16x+24)}{2(x+3)(x+3)}= \\\\\\\dfrac{3x^2+34x+51}{2(x+3)(x+3)}= \\\\\\\dfrac{3x^2+34x+51}{2x^2+12x+18}$

Hope this helps!

What is the vertex of the function h(x) = |x + 6| + 3?

stich3 [128]

$\text{It absolute value equation nis represented as:}\\\\h(x)=a|x-h|+k\\\\\text{Where as h = x coordinate and k = y coordinate}\\\\\text{Now since we know this, find the vertex from:}\\\\h(x) = |x + 6| + 3\\\\\text{6 is in our h value, so that would be our x coordinate. Remember, it has}\\\text{to be the opposite value, so negative}\\\\(-6,k)\\\\\text{Now find k}\\\\\text{3 is our k value, so that'll be our y-coordinate. This one doesn't have to}\\\text{ahve its value changed}\\\\$

$\text{Therefore, your answer is:}\\\\\boxed{\text{B. (-6,3)}}$
