<h3>Answer: <u>11</u> units to the <u>right</u> and <u>3</u> units <u>down</u></h3>

====================================================

Explanation:

Plot the two points on the same xy grid (refer to the diagram below). Once this is done, the answer probably will become apparent. We should move point B 11 units to the right so that we move directly over top point B'. Count out the spaces to see why this is the case, or you can subtract the x coordinates and apply absolute value

|x1-x2| = |-5 - 6| = 11

Then we need to move 3 units down to finally arrive at point B'

---------------------------

A non-visual or non-graph approach could look like this:

B is at (-5,-2) while B' is at (6,-5)

Focus on the x coordinates for now. Like before, we subtract the x coordinates and apply absolute value to get |x1-x2| = |-5 - 6| = 11. This is the "11 units to the right" motion.

Do the same for the y coordinates to get |y1-y2| = |-2-(-5)| = 3. We move down because the y coordinate of B' is further away from 0 compared to the y coordinate of B.

In short, we apply the translation rule (x,y) \to (x+11, y-3) to describe the motion of right 11, down 3.

Andrews [41]

Answer:

Step-by-step explanation:

(x_{1} , y_{1}) = (-8,8)  \\\\(x_2},y_{2}) = (-2 , -6) \\\\Midpoint = \left ( \dfrac{x_{1}+x_{2}}{2},\dfrac{y_{1}+y_{2}}{} \right)\\\\\\= \left(\dfrac{-8-2}{2},\dfrac{8-6}{2} \right)\\\\\\=\left( \dfrac{-10}{2},\dfrac{2}{2} \right)\\\\\\=(-5,1)

Tim and holly left base camo and hiked 6 kilometers north, and turned due west and hiked another 8 kilometers. They stopped and
Marysya12 [62]

Answer:

10 km

Step-by-step explanation:

The Angle formed by their travel is a right angled triangle (check attached picture) , hence we can apply Pythagoras rule :

Hypotenus = sqrt(opposite² + Adjacent²)

Hypotenus = distance hiked after lunch :

D = sqrt(6² + 8²)

D = sqrt(36 + 64)

D = sqrt(100)

D = 10 km

Use properties of addition and subtraction to evaluate the expression. -19 - 53 - 31 Enter your answer in the box.
ivanzaharov [21]
You may combine these 3 numbers in any order.

-19 -53 = -72, and then
-72 - 31 = -103.

You could combine -53 and -31 first, and then combine the result with -19.
