Answer:
2n - 2
Step-by-step explanation:
rewrite without parentheses, pretend there is a 1 between the minus sign and the open parentheses that has to be distributed:
3n - 1(2 + n)
3n - (1)(2) + (-1)(n)
3n - 2 - n
combine 3n and -n to get 2n
2n - 2
B) Translate 4 units down and rotate 180°
Rule for 180° = (x, y) ---- (-x, -y)
Pick one point on Triangle A. (I picked the pointiest point)
(-5, 6)
Now translate 4 units down.
You will now be on (-5, 2)
Rotate 180°
You will now have (5, -2)
And the pointiest point on Triangle B is (5, -2)
So, B is the correct answer.
At x=3 the y output is 7.428. At x=5 the y output is 7.729. Since te rate of change is rise/run, run being the x, you know that it is (something) over 2. The rise would be the difference of the two y outputs. 7.729-7.428= 0.301. Therefore, 0.301/2 would be your answer. Checked by y=0.301/2x+6.975 - the two limes line up at x=3 until x=5 exactly.
B, 60
make a square and a triangle out of the house shape dividing the 150 angles into 90 and 60
