Answer:
(x, y) → (–x, –y)
Step-by-step explanation:
The rule for 180° rotation about the origin is
The coordinates of the image are obtained by negating both the x and y coordinates of the preimage.
Whether the rotation is clockwise or counterclockwise, the rule remains the same.
The correct option is (x, y) → (–x, –y)
Answer:
x = 5
Step-by-step explanation:
Ashley and Adam spent a total of 31 hours on their projects so: 3x+2+4x-6 = 31
3x+2+4x-6 = 31
7x-4 = 31
7x = 35
x = 5
Answer:
7
Step-by-step explanation:
This problem deals with order of operations. If you solve the problem from left to right, you will get an incorrect answer. Instead recall PEMDAS.
Parentheses first
Exponents
Multiplication and Division (left-to-right)
Addition and Subtraction (left-to-right)
We start with the division, as there are no parentheses or exponents. 3÷3=1.
Now we can replace the 3÷3 with a 1 in the expression.
7-1.0+1
Since we only have addition and subtraction left, we now proceed from left to right.
7-1.0=6, and 6+1=7.
or
7-1.0+1=7.
Therefore, the answer is 7.
