Sin(A) = opposite/hypotenuse = 12/13
Cos(A) = adjacent/hypotenuse = 5/13
Tan(A) = opposite/adjacent = 12/5
Answer:
baguettes are b = $0.80
rolls are r = $0.30
Step-by-step explanation:
1b + 4r = 2
3b + 2r = 3 step 1 when we need to balance and make one the same
6b + 4r = 6 step 2 when both equations must have 1 same value ie) 4r we take 2r and x2 to all values on that same equation.
6b + 4r = 6
-
1b + 4r = 2 step 3 when both equations show add we subtract them
5b = 4
b = 4/5
b = 0.8 b = 0.8 = 4/5 step 4 when we find x we plug in for x in this case we found b and plug in for b
1(0.8) + 4r = 2
0.8 + 4r = 2
4r = 2 - 0.8
4r = 1.2
r = 1.2 /4
r = 0.3
(-2x-2) is the correct answer
For y to not be a function of x, there needs to be an x-value that is paired with more than one y-value.
In terms of the sets, you need to find a set where the same x-value is used more than once in two (or more) different (x,y) pairs.
This occurs in the third set, where x=6 is used twice.
