The reflection line is located at y = -x
For point J, x is -2, so y = -(-2), which equals 2.
When it is a reflection across Y, the X values remain the same.
Find the distance of the Y point to the reflection line,
The distance from -1 to 2 is 3 units.
The new point needs to be the same distance from the reflection line.
2 + 3 units = 5.
Point J' would be (-2,5)
answer:
-2x + 9 or -2 which is what the question asks
step-by-step explanation:
- we have to combine like terms which means terms that are similar
- in this, only 5x and -7x are like terms since both have x with them
- 9 will stay the same since it does not have a like term
5x + 9 + (-7x) = __x + 9
-2x + 9
- therefore, -2 goes in the blank
Simple,
You have 11
to change it into an improper fraction multiply the
whole number (11) by the
denominator (8)
11*8=88
Then,
add the numerator to what you have multiplied..
88+5=93
Finally,
use the original denominator....Making your answer...
Thus, your answer.
18! is common to each term in the sum:
18! + 19! + 20! = 18! (1 + 19 + 19×20) = 18!×400
The largest prime factor of 18! is of course 17.
Meanwhile,
400 = 16×25 = 2⁴×5²
so the largest prime factor of 18! + 19! + 20! is 17.
