Oksana_A [137]

Answer:

(3,-3.5)

Step-by-step explanation:

Mid-point formula : \frac{ x_{1} +x_{2}} {2}, \frac{y_{1}+y_{2}  }{2} \\\\x=\frac{7+(-1)}{2}         ,     y=  \frac{2+(-9)}{2} \\x= \frac{6}{2}              ,     y=  \frac{-7}{2} \\x=3                             ,    y= -3.5

Midpoint M of the line segment is (3,-3.5)

ad-work [718]

Answer:

26

Step-by-step explanation:

Given that:

Target amount for NYC trip = $1000

Cost of T - shirt = $9 each

Logo printing fee = $30

Number of T - shirts = x

Number of T - shirts to be sold in other to reach their goal :

[(Cost of logo + Cost of T shirt) * number of shirts sold] ≥ target amount

[($30 + $9) * x] ≥ $1000

$39x ≥ 1000

x ≥ 1000/ 39

x ≥ 25.64

Hence, they have to sell at least 26 t shirts with logo printed to raise $1000
