Answer:

Option B. -j = -h/-k is not correct

Step-by-step explanation:

As from the given scenario both the negative signs will be cancelled out giving positive j : -h/-k = -j

First option has: -j = -h/k In this case also the negative sign from both sides would be cancelled out.

Second option has: -h/-k = -j In this case negative signs cannot be cancelled out.

Third option has: h/-k = -j , negative sign would be cancelled from both sides.

Fourth option has: h/k = j , no negative sign on either side.

i hope it will help you!

Simplify square root of 8y/share root of y

lozanna [386]

Answer:

$2\sqrt{2}$

Step-by-step explanation:

We are required to simplify the following expression;

$\frac{\sqrt{8y} }{\sqrt{y} }$

Using the properties of radicals;

$\frac{\sqrt{a} }{\sqrt{b}}=\sqrt{\frac{a}{b} }$

The expression can be re-written as;

$\sqrt{\frac{8y}{y}}=\sqrt{8}$

Now;

$\sqrt{8}=\sqrt{4*2}=\sqrt{4}*\sqrt{2}\\ \\2\sqrt{2}$

I need help to answer/ solve this

Neporo4naja [7]

Answer:

${x,y}={6,-1}$

Step-by-step explanation:

Solve by Substitution :

// Solve equation [2] for the variable y

[2] y = -x + 5

// Plug this in for variable y in equation [1]

[1] x - 2•(-x +5) = 8

[1] 3x = 18

// Solve equation [1] for the variable x

[1] 3x = 18

[1] x = 6

// By now we know this much :

x = 6

y = -x+5

// Use the x value to solve for y

y = -(6)+5 = -1

Solution :

${x,y} = {6,-1}$
