If d is the midpoint of ef,ed =3x+1,ef=4x+12 find ed

adoni [48]

Since the line contains a midpoint, both sides of the line will be equal each other and exactly one half of the entire line

so basically ed = df
and ed + df = ef

first, we find the value of x
$2(3x + 1) = 4x + 12$
$6x + 2 = 4x + 12$
$2x = 10$
$x = 5$

plug x back into the equation for ef
$4(5) + 12 = ef$
$20 + 12 = ef$
$32 = ef$

What are the possible solutions to the equation: x-12 = sqrt x+44

Ainat [17]

possible solutions for equation $x-12 = \sqrt{x+44}$ is $x=5 , x=20$

<u>Step-by-step explanation:</u>

Here we have to find the possible solutions to the equation: x-12 = sqrt x+44 .Let's find out:

⇒ $x-12 = \sqrt{x+44}$

⇒ $(x-12)^2 = (\sqrt{x+44})^2$

⇒ $(x^2+144-24x) =x+44$

⇒ $(x^2+144-24x) -(x+44) =0$

⇒ $(x^2+100-25x) =0$

⇒ $x^2-25x+100 =0$

⇒ $x^2-20x-5x+100 =0$

⇒ $x(x-20-5(x-20) =0$

⇒ $(x-5)(x-20)=0$

⇒ $x-5=0 , x-20=0\\$

⇒ $x=5 , x=20$

Therefore , possible solutions for equation $x-12 = \sqrt{x+44}$ is $x=5 , x=20$

Find (f/g)(x) f(x)=4x+1 g(x) =3x-4

mash [69]

Your answer is very close to being correct; however, the true answer is actually $\frac{4x+1}{3x-4}$ without any parenthesis needed around the fraction. Notice how there is no (x) at the end.
