|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

The value of Peter's house has risen 20% a year for the last 3 years. If the value of Peter's home 3 years ago was $110,000.00,
IRISSAK [1]
Increase $110,000 by 20% 3 times.

110,000 x 0.2 = 22000
(0.2 is 20% as a decimal, we needed to convert it to multiply it)

So we must add 22000 to 110,000, then take 20% of the new cost, and repeat.

Add them
110,000 + 22000 = 132000

Take 20% of new value
132000 x 0.2 = 26400

Add that
132000 + 26400 = 158400

Take another 20% of that
31680

Add them
158400 + 31680 = 190080

So the value is now $190,080

A much more efficient way to do this would be multiplying 1.2 instead of 0.2, and skipping the adding part, as you already took 100% of it and are adding 20% more.

Hope this helps!

The center of a circle is at the origin on a coordinate grid. A line with a positive slope intersects the circle at (0, 7). Whic
denis23 [38]

The true statement is the circle has the radius equal to 7.

<h3>What is Equation of circle?</h3>

The general equation for a circle is (x-h)² + (y-k)² = r², where ( h, k ) is the center and r is the radius.

As, standard form of equation of circle is

(x-h)² + (y-k)² = r²

At origin, equation of circle will be

(0-h)² + (0-k)² = r²

r² = x² + y²

Now, The line intersects the circle at (0,7)

r² = 0² + 7²

r² =49

r=7.

Hence, the circle has the radius equal to 7.

Linear equation for (-5,3) and (-1,-1)
Alex787 [66]

Answer:

y = -x - 2

Step-by-step explanation:

y = mx + c

m = (-1-3)/(-1-(-5)) = -4/4 = -1

y = -x + c

(-1,-1)

-1 = -(-1) + c

c = -2

y = -x - 2
