Solve the system of equations and choose the correct ordered pair. 3x + 5y = 2 9x +11 y= 14

A. (4, -2)

B. (4,2)

C. (3,-2)

D. (3,2)

(4,-2)

Step-by-step explanation: elimination method

3(3x+5y)=2×3

9x+11y=14

9x+15y=6

-

9x+11y=14

4y=-8

y=-2

To get x replace y with -2

3x+(5×-2)=2

3×=12

X=4

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
