Answer:
6cm ; 22cm
Step-by-step explanation:
Given that:
Total Length, AD = 28cm
AB =x cm
BC = (x +5)cm
CD = 2x - 1 cm
4x + 4 = 28
4x = 28 - 4
4x = 24
x = 24 / 4
x = 6cm
The length of BD
BD = BC + CD
BD = (x + 5) + (2x - 1)
x = 6
BD = (6 + 5) + (2(6) - 1)
BD = 11 + (12 - 1)
BD = 11 + 11
BD = 22 cm
Answer:the map notation is (x,y) to (y,-x) at a 90 degree angle
180 degrees map notation is (x,y) to (-x,-y)
360 degrees map notation is (x,y) to (-y,x)
Step-by-step explanation: the answer is they are congruent
Answer:
B
Step-by-step explanation:
We dont know rules about rotating a point. We only know rules about rotating about the orgin.
We can translate this line segment so point c is on the orgin because
- A translation is a rigid transformation
- We also know rotation rules about the orgin.
Point C is at (1,3) so let move this all points 1 to the left and 3 down. Why All Points?
A translation is parallel from it original image to its second or new image so this means Point B and Point A will both move as well. Let just focus on Point A. The new coordinates are:
Let apply the 90 degree clockwise rule. Point C doesnt move since it is at the orgin and it at the center of rotation.
(x,y) goes to (y,-x).
So Point A prime is now at
(0,-1).
Now let translate the figure back to Point C (1,3). by going 1 to the right and 3 up so our new point of Point A prime is at
(1,2).
Answer:
Kayla should mark the level 3 whole tick marks to the left of the zero on the number line.
Step-by-step explanation:
This would mean the number is negative, for it is on the left of the zero. Another way to say this could be that the absolute value of -3 is three, for it is three whole tick marks from the zero.
