The mixed number have to become a improper fraction and then you have to subtract like this.

so 7 7/8 you have to multiply 7 times 8 and then add it by 7 .
You do the same thing with the other mixed number 3 times 4 plus 1 

So the first one is 63/8 - 13/4 =

first the 4 in the 13/8 have to become 8 . so you do 4 times 2 = 8 and multiply the 13 by 2 = 26 .
so equal 

63/8 - 26/8 = then you have to do 63 - 26 = 37 so is 37/8 and then simplify or divide .

when you divide you suppose to get 4 5/8

Which graph represents f(x)=−2cos(4πx)?
algol [13]

Answer:

the last one (bottom right)

Step-by-step explanation:

4×pi is the same as twice around the whole circle to the beginning. it is the same as 0°, and cos(0) = 1, and then -2×cos(0) = -2

so, we only need to look, where the function reaches -2.

it should be at x = 0, x = 0.5 and x = 1.
