Answer is 12 to your question
Answer:
n=35
Step-by-step explanation:
-3(n-16)= -57
-3n+48= -57
-48 -48
-3n= -105
/-3 /-3
n= 35
Answer:
Yes!
Step-by-step explanation:
Here is a trick. If you add up all of the numbers in the number, and if that is divisible by three, the number is divisible by three. So...
5+3+6+1=15
15 is divisible by 3,
so 5361 is divisible by 3
(if you wanted to know, it is 1787)
In analytical geometry, there are already derived equations to find the distance of lines and points as well as the angle made between two lines. As special case is when the other line is one of the coordinate axis. Then, the formula can be simplified to
tan θ =m, where m is the slope of the equation
In the next step, we also incorporate operations of calculus. Since the slope is equal to Δy/Δx, this is equivalent to dy/dx in calculus. Therefore, you can find the slope by differentiating the equation in terms of x.
<span>y-2x=7
y = 2x+7
dy/dx = 2 =m
So,
tan </span>θ = 2
θ = tan⁻¹(2)
θ = 63.43°
