X² + 10x + 25 = 8
(x + 5)(x + 5) = 8
(x + 5)² = 8
x + 5 = +-√8
x + 5 = +-(√4 × √2)
x + 5 = +-(2√2)

first solution
x + 5 = +2√2
x = -5 + 2√2
x = 2√2 - 5

second solution
x + 5 = -2√2
x = -5 - 2√2
x = -2√2 - 5

The answer is first option and second option

Your take home pay is $1500 and you have 22% withheld in taxes. What is your gross pay?

wlad13 [49]

We have been given that the take home pay is $1500 and 22% is withheld as taxes.

Let us assume that the gross pay is x dollars. Therefore, take home pay must be 78% of x because 22% of the pay is withheld as taxes, so you get to take home only 78% of the gross pay.

Since we have been given that take home pay is $1500 and it is 78% of the total gross pay. Therefore, we can set up an equation:

$78\%\text{ of }x=1500\\\frac{78}{100}x=1500\\0.78x=1500\\x=\frac{1500}{0.78}\\x=\$1923.08$

Therefore, gross pay is $1923.08

Norma-Jean [14]

Answer:

$y + 4 = -\frac{5}{6}(x - 8)$

Step-by-step explanation:

In the Point-Slope Formula, $y - y_1 = m(x - x_1),$ all the negative symbols give the OPPOSITE terms of what they really are, so be EXTREMELY CAREFUL inserting the coordinates into the formula with their CORRECT SIGNS.
