Answer:
When we reflect over the y-axis, sign of the x-coordinate changes.
Step-by-step explanation:
Since we know when we'll reflect over y-axis, y-axis will work as a mirror. Y-coordinates will remain same but the only change that happens to any point on the graph is x coordinates.
In second quadrant x-coordinates are negative and in first quadrant positive, while y coordinates are positive in both first and second quadrant. So if we will reflect from first to second or second to first quadrant y-coordinates will remain same but x-coordinates will change..
In third quadrant x-coordinates are negative and in fourth positive, while y coordinates are negative in both third and fourth quadrant. So if we will reflect from third to fourth or fourth to third quadrant y-coordinates will remain same but x-coordinates will change.
Therefore, from above explanation we can conclude that when we reflect over the y-axis, sign of the x-coordinate changes.
Answer:
$3.3075
Step-by-step explanation:
1 kilogram = 2.205 pounds
So we will multiply the $1.50 by 2.205 to get the cost per pound of rice
1.50 * 2.205 = $3.3075

Answer:
3120
Step-by-step explanation:
step 1:multiply 8 with 0 and 7 with 0
step 2:add a 0 in the end and multiply 8 with 4 . you get 32. take 2 and carry over 3. multiply 7 with 4. you get 28 . add 3 you get 31. now add. you get 3120
