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).
Answer:
The simplified expression for the given expression will be:
c.
Step-by-step explanation:
Given expression:
To simplify the expression.
Solution:
In order to simplify the expression, we will first remove the parenthesis by reversing the signs of the terms inside the parenthesis which lies after a negative sign out side the parenthesis.
<em>This is because negative multiplies to a negative to give a positive and negative multiplies to a positive to give a negative.</em>
So, we have:
⇒
Combining like terms
⇒
<em>The like terms can be evaluated as</em>
Thus, the simplified expression will be:
⇒
