Answer:

Step-by-step explanation:

Sounds as tho' possible answer choices were listed. Please, share them without being asked to do so. Thank you.

7√(x²) 7√(x²)

------------- = ----------------------

5 √(y³) 5√( y^(3/2) )

We want to get the fractional exponent out of the denominator. To do this, multiply both numerator and denominator by y^(1/2):

7√(x²) 7√(x²) y^(1/2) 7√(x²)·y^(1/2) 7x√y

------------- = --------------------- * ----------- = --------------------- = ----------

5 √(y³) 5√( y^(3/2) ) y^(1/2) 5 √(y²) 5y

This is the final answer. We have succeeded in removing radicals / fractional exponents from the denominator.

Help? Sorry if it’s pink

3 = 3/4(b - 8)
Switch sides
3/4(b - 8) = 3
Next, multiply both sides by 4
4 * 3/4(b - 8) = 3 * 4
Then simplify,
3(b - 8) = 12
Next, divide both sides by 3
3(b - 8)/3 = 12/3
Then, simplify
b - 8 = 4
Then, add 8 to both sides
b - 8 + 8 = 4 + 8
Simplify, b = 12

Emmanuel added two integers Which condition will always give Emmanuel a negative solution when he adds two integers? Both intege

alexgriva [62]

Both integers have negative values

Explanation

Let

x and y represents the number

so, the options are

$\begin{gathered} +\text{ + +} \\ +\text{ + -} \\ -\text{ + +} \\ -\text{ +-} \end{gathered}$

a) Both integers have negative values Both integers

$-x-y=-(x+y)\rightarrow you\text{ will always get a negative number}$

b) Both integers have positive values

$x+y=+\text{ + += you will always get a positive number}$

c)One integer has a positive value, and one integer has a negative value

$\begin{gathered} -x+y\text{ or x-y} \\ the\text{ sign of the result depends on the greates absolute value, it means the answer will have the same of the bigger number( absolute value)} \end{gathered}$

d)The values of the two integers are opposites

as the point C , the sign depends on the bigger number

for example

$\begin{gathered} 8-5=3\text{ positive because 8 is the bigger} \\ 5-8=-3\text{ negative because (-8) is has the bigger absolute value} \end{gathered}$

so, the answer is Both integers have negative values

I hope this helps you
