You can do C(6,2) which gives

which is
15!
Answer:
Angle, 
Step-by-step explanation:
We have, an A-frame house is 45 feet high and 32 feet wide. It is required to find the measure of the angle that the roof makes with the floor.
The attached figure shows the A frame. Let
is the angle that the roof makes with the floor. So,

So, the angle of 70.4 degrees is the angle that the roof makes with the floor.
Well you can't actually find a number, but you can make an equation.
lets call the bag of candy x, and the number of students in the teachers class S.
she gives every student in her class 4 pieces, so to find that amount, we have to multiply the number of students in her class by 4, the pieces of candy. 4S
afterwards she has 48 pieces, which is the endpoint, x is the starting point because that's the amount of candy the teacher started with.
so your equation is x-4S=48, but the thing is, the question is looking for the amount of students she gave candy to, so we have to isolate S, or in easier words; put S on one side, and the numbers on the other.
so the equation is S=1/4x-12
Answer:
phase shift and period change
Step-by-step explanation:
just did it
solve this answer by using substitution. set the first equation to x=-y+4 then substitute -y+4 for x in the second equation.
2(-y+4) + 3y=0
-2y+8 + 3y=0
y+8=0
y=-8
now use -8 and solve for x
x+(-8)=4
x=12
