An you help me now with these |x + 2| + 16 = 1 i need help :( |2x + 6| − 4 = 20 nd help solving
krok68 [10]
|x + 2| + 16 = 1
<u>           - 16  - 16</u>
        |x + 2| = -15
         x + 2 = -15    U    x + 2 = 15
         <u>    - 2     - 2</u>          <u>    - 2    - 2</u>
               x = -17                 x = 13

|2x + 6| - 4 = 20
<u>            + 4   + 4</u>
     |2x + 6| = 24
      2x + 6 = 24    U    2x + 6 = -24
      <u>     - 6    - 6</u>           <u>     - 6      - 6</u>
            <u>2x</u> = <u>18</u>                 <u>2x</u> = <u>-30</u>
             2      2                   2       2
              x = 9                     x = -15

Which choice is the equation of a line that passes through the point (–2, 8) and is perpendicular to the line represented by thi
Vedmedyk [2.9K]

Answer:

<h2>C. 2x + 5y = 36</h2>

Step-by-step explanation:

\text{If}\ A_1x+B_1y=C_1\ \text{is perpendicular to}\ A_2x+B_2y=C_2,\ \text{then}\\\\\dfrac{A_1}{B_1}=-\dfrac{B_2}{A_2}.\\\\\text{We have the equation:}\ 5x-2y=-10\to A_1=5,\ B_1=-2.\\\\\dfrac{A_1}{B_1}=\dfrac{5}{-2}\to-\dfrac{B_2}{A_2}=-\dfrac{5}{2}\qquad\text{change the signs}\\\\\dfrac{B_2}{A_2}=\dfrac{5}{2}\to A_2=2,\ B_2=5\\\\\text{Therefore the equation of a perpendicular line is:}\\\\2x+5y=C\\\\\text{Put the coordinates of the given point and solve for}\ C:\\\\2(-2)+5(8)=C\\\\C=-4+40\\\\C=36\\\\\text{Finally:}\\\\2x+5y=36

Find the sum of the geometric sequence –3, 15, –75, 375, … when there are 9 terms and select the correct answer below.
ZanzabumX [31]
The correct answer to the question presented above would be letter A. -976, 563. I got this through solving with the first number of the set, then getting the ratio of the data set (which is -5) and the number of terms in the set. Thus, I arrived with the answer, -976, 563.
