Which coordinate lies in the solution set for
tatyana61 [14]

Answer:

Step-by-step explanation:

to do this, u would just sub ur answer choices into the inequalities and see what is true. Keeping in mind, that ur point has to satisfy both inequalities for it to be a solution.

2x + y < 12...subbing in (3,3)        3x - 2y > 2...subbing in (3,3)

2(3) + 3 < 12                                   3(3) - 2(3) > 2

6 + 3 < 12                                        9 - 6 > 2

9 < 12....true                                       3 > 2....true

(3,3) lies in the solution set <==

For the point P (-17,25) and Q(-10,30), fins the distance d(P,Q) and the coordinates of the midpoint M of the segment PQ.
Nonamiya [84]

Answer:

Distance = 8.6

M = (-13.5,27.5)

Step-by-step explanation:

Distance = \sqrt{(x_{2 }- x_{1 })^2 + (y_{2 }- y_{1 })^2

= \sqrt{(-10_ }- (-17)_{ })^2 + (30_{ }- 25_{ })^2

= \sqrt{(-10_{ }+ 17_{ })^2 + 5^2_

= \sqrt{7^2+5^2}

= \sqrt{49+25}

= \sqrt{74}

= 8.6

Midpoint = (\frac{x_{2}+x_{1}}{2};\frac{y_{2}+y_{1}}{2})

= (-10+(-17)) ÷ 2 ; (30+25) ÷ 2

= -27 ÷2 ; 55 ÷ 2

= -13.5, 27.5
