Answer:
64
Step-by-step explanation:
Given coordinates of the triangle: A(2,2), B(7,1) and C(8,-4).
We are given that image is rotated 90° counterclockwise about the origin.
In order to find the new coordinates of rotatation 90°counterclockwise about the origin, we can apply rule (h, k) ---> (-k,h).
Where (h,k) are the coordinates of original image on axes and (-k,h) are the coordinates of rotated image.
In resulting coordinates of the image first swap the x and y coordinates of the original image and then make the sign opposite of each x-coordinate.
On applying rule (h, k) ---> (-k,h), we get
A(2,2) --> A'(-2,2).
B(7,1) --> B'(-1,7).
C(8,-4) --> C'(4,8).
Answer:
87
Step-by-step explanation:
tn= a + (n-1)d
t12 = 10 + (12-1)7
=87
28:21
because the same number has to multiply both sides of the ratio. so number = 7 and:
4x 7 = 28
3 x 7 = 21

Answer:
(1) x(2/3) = y
(2) 27
(3) 8
(4) 9
Step-by-step explanation:
The first line of the table tells you how to fill in the second line. Use the x and y values from the third line to write (y/x) = (2/3). This gives you the equation ...
x(2/3) = y . . . . line (1)
For the remainder of the table, you can use the given value compared to the value in line 3 to see what the multiplier is for the other value.
(2): The multiplier is 18/2 = 9, so the missing x-value is 3×9 = 27.
(3): The multiplier is 12/3 = 4, so the missing y-value is 2×4 = 8.
(4): The multiplier is 6/2 = 3, so the missing x-value is 3×3 = 9.
