If LN = 6x - 5, LM = x + 7, and MN = 3x + 20, find MN
Ostrovityanka [42]

Answer:

68

Step-by-step explanation:

LM   +    MN     =   LN

x + 7  + 3x + 20 = 6x - 5

           4x + 27 = 6x - 5

          -4x         -4x      

                   27 = 2x - 5

                    +5        +5

                   32  = 2x

                   ÷2   ÷2    

                    16 = x

MN: 3x + 20

      3(16) + 20

        48   + 20

              68

Draw a line representing the "rise" and a line representing the "run" of the line. State the slope of the line in simplest form.
Romashka-Z-Leto [24]

The slope is \frac{-3}{5}

Step-by-step explanation:

You know the slope is negative if you start on the left side and move right along the line.  You are moving down hill.  Down hill is a negative slope.

How do you solve and graph a piece wise function and state the domain and range?
nevsk [136]
For 3)  check the picture, on the right-hand-side

now for 4) check the picture on the left-hand-side

if you notice the intervals, it goes from -∞ and stops at -2, then goes from 2 over to 3, then from 3 onwards, so the domain will also be (-∞ , +∞).

Now, the range...

the 1st subfunction 3-x is just a line coming down form -∞....

the 2nd subfunction is just 2x, also a line going up, now once you get to

the 3rd subfunction is just 5, meaning y = 5, or f(x) = 5, which is just a horizontal line at y = 5.

since the 3rd subfunction goes from x > 3 onwards to +∞, and is just a horizontal line, it doesn't go below 5, so one would think the range is -∞, 5.

however, from the 2nd subfunction if we use say x = -1.9999, 2x ---> 2(-1.9999) = -3.9998 , that's lower than 5, and that's the lowest the piece-wise goes, thus, the range comes from -∞ and goes as low as -3.9998,  (-∞ ,-3.9998]

notice, we didn't use -2, because the 2nd subfunction 2x, doesn't include it in its range -2 < x ⩽ 3.

now, for 4) I used -1.9999 but your teacher might be expecting something like -1 or thereabouts, just an integer amount.  But the idea being, the 2nd subfunction, does not include the -2.
