1. First add 9 to both sides, then divide by negative 16. M= -1
2. I don't know what's being added to -19, i'm assuming it's X. just add 19 to both sides you'll get that X=16

-for # 1 I would add 9 to both sides to get 16 so m = 1
for # 2 I would subtract 19 -3 to get 16. -3=-19 + 16

The cost to produce a custom designed t shirt is five dollars per shirt plus a 40 dollar design fee. Which of th following could

ehidna [41]

Ok so if we have five dollars per shirt, and if the number of shirts we buy is x, we have 5x dollars for the price. there is also a $40 design fee, so that adds 40. we do not need to pay 40 for every shirt, just once for the whole group, so we have 5x+40 as our answer

Select the two values of x that are roots of this equation.<br>x + 2x - 6 = 0

VLD [36.1K]

For this case we must solve the following quadratic equation:

$x ^ 2 + 2x-6 = 0$

Where:

$a = 1\\b = 2\\c = -6$

The solution is given by:

$x = \frac {-b \pm \sqrt {b ^ 2-4 (a) (c)}} {2a}$

Substituting:

$x = \frac {-2 \pm \sqrt {2 ^ 2-4 (1) (- 6)}} {2 (1)}\\x = \frac {-2 \pm \sqrt {4 + 24}} {2}\\x = \frac {-2 \pm \sqrt {28}} {2}\\x = \frac {-2 \pm \sqrt {2 ^ 2 * 7}} {2}\\x = \frac {-2 \pm2 \sqrt {7}} {2}\\x = -1 \pm \sqrt {7}$

Thus, we have two roots:

$x_ {1} = - 1+ \sqrt {7}\\x_ {2} = - 1- \sqrt {7}$

ANswer:

$x_ {1} = - 1+ \sqrt {7}\\x_ {2} = - 1- \sqrt {7}$
