Help plz what is 7-6v=-5-8v

kirill115 [55]

v=-6 is the right answer. First you had to subtract by 7 from both sides of equation, and it gave us, $7-6v-7=-5-8v-7$ . And then simplify, and it gave us, $-6v=-8v-12$ . You can also add by 8v from both sides of equation, and it gave us, $-6v+8v=-8v-12+8v$ . Next simplify, and it gave us, $2v=-12$ . Then you divide by 2 from both sides of equation, and it gave us, $\frac{2v}{2}=\frac{-12}{2}$ . And finally simplify, and it gave us the answer is v=-6 is the right answer. Hope this helps! And thank you for posting your question at here on brainly, and have a great day. -Charlie

I NEED HELP ASAP SOMEONE HELP ME PLEASE, I MEDD SOMEONE WHO CAN HELP ME WITH THE REST OF MY QUESTIONS

Vikentia [17]

Answer:

Step-by-step explanation:

K(0 , 4)

Midpoint M (3 , 3)

Let Point L(x₂ , y₂)

$Midpoint= (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}\\\\\\ (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2}) = (3 , 3)\\\\\\ (\frac{0+x_{2}}{2},\frac{4+y_{2}}{2}) = ( 3 , 3)\\\\\\$

Compare x and y coordinates

$\frac{x_{2}}{2}=3 ; \frac{4+y_{2}}{2} = 3$

Cross multiply,

x₂ = 3*2 ; 4 + y₂ = 3*2

x₂ = 6 ; 4+ y₂ = 6

y₂ = 6- 4

y₂ = 2

L(6 , 2)

Divide completely for the question below

juin [17]

Answer:

B) 5x^2

Step-by-step explanation:

$\sqrt{\frac{50x^5}{2x} }$

We can divide 50 by 2, we get 25 and we can cancel out x from x^5.

Therefore, we get

$\sqrt{\frac{25x^4}{1} }$

= √25x^4

When we take the square root of 25, we get 5 and √x^4 = x^2.

Taking the square root, we get

= 5x^2

Answer: B) 5x^2

Thank you.
