Answer:
What are the original coordinates?
Answer:
x=27
Step-by-step explanation:
3x+9 is a right angle because 3x+9 + a right angle make a straight line
3x+9 +90 = 180
Subtract 90 from each side
3x+9 = 90
We now can solve for x
3x+9-9 = 90-9
3x = 81
Divide each side by 3
3x/3 = 81/3
x=27
Add Midterm Elections as an interest to stay up to date on the latest Midterm ... Party ID: Democrats account for 38 percent of voters in exit poll results so far, ... The previous highs in midterm elections were 13 percent for blacks, in 2014; and 8 ... Republican House candidates in preliminary exit poll results.
It would be, 33%.
Hope this helps!
Answer:
X-19
Step-by-step explanation:
First you need to distribute the three into the numbers in the parenthesis,
(3 * x) + (3 * -5) - (2x + 4)
That then turns into,
3x - 15 - (2x + 4)
but we aren't done distributing yet, because the second set of parenthesis has a negative sign in front of it we also have to distribute that. (this is because the negative sign is really just -1)
3x - 15 + (-1 * 2x) + (-1 * 4)
that turns into,
3x - 15 - 2x -4
from here all we have to do is add like terms,
(3x - 2x) + (-15 + -4)
and that leaves us with: 1x -19 or x-19
Hope that helped :))
