Question

The underground water pipe between two streets is damaged. Half the length of the pipe needs to be changed. The layout of the pipes on a coordinate grid shows one end point of the pipe at (-6, 1) and its midpoint at (-2, 3). Troy performed the steps shown to find the coordinates of the other endpoint of the pipe.

Answer 1

hi yazzy, You seem curious @lgbasallote will help you better than me

Answer 2

Step 1. x1 = -6, y1 = 1, x = -2, y = 3
Step 2.
Step 3.
Step 4. 4 = -6 + x2, 6 = 1 + y2
Step 5. 10 = x 2 , 5 = y2

In which step did Troy first make an error?
Step 3, because he substituted the incorrect values in the formula.

Step 4, because he found the product of -2 and 2 to be 4 instead of -4.

Step 2, because he used the incorrect formula to find the midpoint.

Step 5, because he found the difference of 6 and 1 to be 5 instead of -5.

Answer 3

Step 4, because he found the product of -2 and 2 to be 4 instead of -4.

Answer 4

I m bad @ EXPLAINING

Answer 5

Omg, thank you so much, can I ask another one ? :)))

What is the length of the segment PQ of the roof rounded to the nearest hundredth?
11.66 units

12.00 units

12.65 units

6.00 units

Answer 8

as per the rules and law it must be

12.00 units
If a fig.. woul be there

Answer 9

then its 6.00

Answer 10

How can you check if a segment is an angle bisector of a triangle?

Check if measures of the two angles the segment divides the vertex angle into are the same.

Check if the areas of the two triangles the segment forms are equal.

Check if the segment meets a side of the triangle at a right angle and divides the vertex angle into two congruent angles.

Check if the segment meets a side of the triangle at a right angle and divides the side into two congruent parts.

Answer 11

obviously,

Check if the segment meets a side of the triangle at a right angle and divides the side into two congruent parts.

Answer 12

Thats what I said, and my sister told me it was wrong, omg, you are a life saver!!

Answer 13

Okay last last last question i promise okay? :D

Answer 14

thanks
I think she asked it to clarify

Answer 15

all the best

Answer 16

Haley constructed the obtuse isosceles triangle RST as shown in the figure below.



What is the error in Haley’s construction?

She plotted point T to the right of the perpendicular line.

She did not ensure that side RS is congruent to side RT.

She plotted two vertices on the arc.

She did not plot point R on the arc.

Answer 17

fig..

Answer 18

Look at triangle KLM. Segment ME is 21 inches.



Which of these could be the dimensions of the segments in the triangle?

ME = 21 inches, MO = 14 inches

FK = 20 inches, KO = 10 inches

GO = 10 inches, LO = 10 inches

MO = 9 inches, EO = 3 inches

Answer 19

firstly look to it if it's definition "
An obtuse angle is more than 90° but less than 180°

In other words, it is between a right angle and a straight angle"
