Triangle XYZ has vertices X(1, –1), Y(3, 4), and Z(5, –1). Nikko rotated the triangle 90° counterclockwise about the origin. What is the correct set of image points for triangle X’Y’Z’?
X’(1, 1), Y’(-4, 3), Z’(1, 5)
X’(1, 1), Y’(–3, –4), Z’(–1, –5)
X’(–1, 1), Y’(–3, –4), Z’(–5, 1)
X’(–1, –1),Y’(4, –3), Z’(–1, –5)
Answer:
When a figure is rotated counterclockwise about the origin, its original coordinates of point P (x,y) will now be positioned as P' (-y,x).
X (1,-1) --> X' (1,1)
Y (3,4) --> Y' (-4,3)
Z (5,-1) --> Z' (1,5)
The correct set of image points for triangle X'Y'Z' is X'(1,1), Y'(-4,3), and Z'(1,5).
Step-by-step explanation:
Triangle XYZ is rotated 90° counterclockwise, the new coordinate is X'(1, 1), Y'(-4, 4) and Z'(1, -5)
TransformationTransformation is the movement of a point from its initial location to a new location. Types of transformation are translation, reflection, rotation and dilation.
If a point A(x, y) is rotated 90° counterclockwise the new point is A'(-y, x).

1. The diameter of a circle is 8. what is the radius?
Answer:
Radius = 4
Step-by-step explanation:
r = d/2
r = 8/2
r = 4
Answer:
4
Step-by-step explanation:
The diameter of a circle is the length of a straight line from two opposite points on the circle. The radius is the length of a straight line from the middle to a point on the circle. This means that the diameter must be double the radius. So to find the radius, divide the diameter by 2. Since 8/2=4, the radius is 4.

Which of the following is not the same as positive 3?
1. 3 units to the left of 0 on a number line
2. the opposite of -3
3. +3
4. 3
what’s the awnser? 1,2,3, or 4
answer:
3 units to the left of 0 on a number line
step-by-step explanation:
your asking for the opposite of positive 3 which just means your looking for a negative 3 ( also written like this -3 )
and going left on a number line means going down on a number line so if your going into the negatives if you started at 0
here is a small number line to help me explain this better
<----|----|----|----|----|----|----|----|----|----|----|---->
-5 -4 -3 -2 -1 0 1 2 3 4 5
* ( the star is you and your starting off at the #0 )
<|-(-1)-(-1)-(-1)- = -3 ( taking 3 jumps to the left )
*
( and now the star is at -3 which was the number you needed )

1. Quadrilateral ABCD has AB = x+3 and CD= 5x –7. What is the length of x
for which the quadrilateral is a parallelogram?
Answer:
x = 2.5
Step-by-step explanation:
since it's a parallelogram, AB = CD so:
x + 3 = 5x - 7
subtract x from each side of the equation:
3 = 4x - 7
add 7 to each side:
4x = 10
divide both sides by 4:
x = 2.5

Leilani wants to make 8 placemats. For each placemat she needs 18 in of fabric. How many yards of fabric will she need for
the 8 placemats?
Answer:
144 yarns of fabric
Step-by-step explanation:
If 8 placemat =18 fabrics
then 8 p placemats=8x18
=144
Leilani wants to make 8 placemats. For each placemat she needs 18 in of fabric. Leilani will need 4 yards of fabric to make the 8 placemats.
To determine the amount of fabric Leilani will need for 8 placemats, we need to convert the given length from inches to yards.
Given:
Length of fabric needed for one placemat = 18 inches
To convert inches to yards, we divide the length in inches by 36 (since there are 36 inches in a yard).
18 inches / 36 = 0.5 yards
Therefore, for one placemat, Leilani will need 0.5 yards of fabric.
To find the total amount of fabric needed for 8 placemats, we multiply the fabric requirement for one placemat by 8:
0.5 yards/placemat * 8 placemats = 4 yards
Leilani will need 4 yards of fabric to make the 8 placemats.
