There are at least a few ways to do it, one of them being:
$8 - $5 = $3, so we may want to find out how much percent of 5 is 3.
3 = x% of 5
3 = x/100 * 5
3 = x/20 * 1
3 = x/20 / * 20 (both sides)
x = 60 [percent]
So now we know that 3 is 60% of 5. It also means that the increase from $5 to $8 was by <u>60%</u><u />.
Answer:
B) (x,y) -> (-x,y)
Step-by-step explanation:
By reflecting across the y axis, all y values stay the same, therefore no matter what happens to the x, the second half will be y -> y
Because of the reflection across the y axis, you are simply taking all x values and multiplying by -1 to get x -> -x.
Thus, (x,y) -> (-x,y)
The simplified version would be 16x+3
