Answer:
x=7, y=16
Step-by-step explanation:
2x+5=x+12
2x=x+7
x=7
y-4=x+5
y-4=12
y=16
(n+1)x 2=10
2n+2=10
2n=8
n=4
Answer:
9/10
Step-by-step explanation:
step 1
Compare the slopes



therefore
An experienced skier would like the 9/10 hill slope because it is steeper, while the 1/10 is a softer slope.
"x" always goes on the left side and "y" always goes on the right side of the parentheses. If you only have an "x" then you will just put a zero in for "y" and vice versa. I hope this helps.
No such thing as cot (61,4). I think you meant to say cot (61.4°). See the difference?
So, cot (61.4°) is approximately -0.139844.
Rounded to 3 decimal places we get -0.140.
