Negative because it is going down
check the picture below.
all angles at point E are right-angles, therefore x + 20 = 90, meaning x = 90 - 20.
The last two are not ways to decompose 1 3/4 since
3/4 + 5/4 =8/4 which equals 2, so it's not 1 3/4
and 1+ 1/2 + 2/2 (=1) so it's 1+ 1/2+ 1= 2 1/2
The answer is 6.
EXPLANATION
All you have to do is to distribute the exponent outside of the parentheses to the constant inside.
That is,
Answer:
D
Step-by-step explanation:
It's decreasing then once it hits the origin, it starts to increase again. I hope this helps you:)
