2 times 2 times 2 times 2= 16
Answer:
second picture
Step-by-step explanation:
The rule to rotate a point counterclockwise about the origin is:
Or in words, we switch the coordinates of the point and change the sign of the y-coordinate.
We know from the first picture that the coordinates of our quadrilateral ABCD are A = (-1, 0), B = (0, -1), C = (-2, -3), and D = (-3 , -2), so let's apply the rotation rule to each one of those points:
Now we know that the coordinates of the quadrilateral after a rotation of 90° are A' = (0, 1), B' = (1, 0), C' = (3, -2), and D' = (2, -3), which corresponds to the second picture
Answer: 8x²+4x-4
Step-by-step explanation:
(f+g)(x) is f(x)+g(x). Since we are given f(x) and g(x), we can directly add them together.
3x²-2x+4+5x²+6x-8 [combine like terms]
8x²+4x-4
Answer:
3 + ? = 7, 3 + n = 7, 3 + x = 1
