Answer:
B
Step-by-step explanation:
1. A reflection across the origin has a rule
2. A translation 9 units to the left and 7 units down has a rule
Then the rule for a reflection across the origin followed by a translation 9 units to the left and 7 units down is
This means that the point with coordinates (x,y) has the image with coordinates (x',y')=(-x-9,-y-7).
The correct answer is: 330
Explanation:
The formula for combination is given as follows:
--- (1)
Where n = 11
r = 4
Plug in the values in equation (1) and calculate:
Hence the correct answer is 330.
The above expression is not in its simplest form, and we need to simplify it, that is what asked in the question.
Given equation,
First of all, let's open the parentheses to combine the like terms for simplifying.
Arranging the like terms, x² with x², x with x and constant terms near to each other.
Simplying further,
So, the correct option is C
