(A/B)+(C/D) anyone know how to solve or simplify this? It’s fractions

JulijaS [17]

Hey!

How are you?? I'd love to assist you today :)

First, remove the parentheses.

Now you have <em>A/B + C/D</em>

Now, rewrite the expression with a common denominator.

AD + CB / BD

That would be the official answer to the question. Make sure to ask any questions.

NEED HELP ASAP solve for x : 3/5 = x-1/8 <br>a.5 b.29/5 c.23/5 d.19/5

Levart [38]

Answer:

<h3> $\boxed{ \sf{ \bold{ \huge{ \boxed{ \frac{29}{5} }}}}}$ </h3>

Option B is the correct option.

Step-by-step explanation:

$\sf{ \frac{3}{5} = \frac{x - 1}{8} }$

Apply cross product property

⇒ $\sf{ 5(x - 1) = 3 \times 8}$

Distribute 5 through the parentheses

⇒ $\sf{5x - 5 = 3 \times 8}$

Multiply the numbers

⇒ $\sf{5x - 5 = 24}$

Move 5 to right hand side and change it's sign

⇒ $\sf{5x = 24 + 5}$

Add the numbers

⇒ $\sf{5x = 29}$

Divide both sides of the equation by 5

⇒ $\sf{ \frac{5x}{5} = \frac{29}{5} }$

⇒ $\sf{x = \frac{29}{5} }$

Hope I helped!

Best regards!!

Suppose a parabola has vertex (–4, 7) and also passes through the point (–3, 8). Write the equation of the parabola in vertex fo

loris [4]

The equation for a parabola can also be written in the "vertex form":
$y = a (x-h) ^ 2 + k
$
Where,
the vertex of the parabola is the point (h, k).
The value of a is the term that accompanies x ^ 2
Substituting values we have:
$y = a (x - (- 4)) ^ 2 + 7
$
Rewriting we have:
$y = a (x + 4) ^ 2 + 7
$
For the point (-3, 8) we have:
$8 = a (-3 + 4) ^ 2 + 7
$
From here, we clear the value of a:
$8 = a (1) ^ 2 + 7

8 = a + 7

a = 8 - 7

a = 1$
Then, the equation is given by:
$y = (x + 4) ^ 2 + 7$
Answer:
The equation of the parabola in vertex form is:
$y = (x + 4) ^ 2 + 7$
