Each X and Y in the equations don't have a number in front of them so they are all considered 1.
D = 1*(-1) - 1*(-1) = -1 -1 = -2
The answer is -2
Answer:
1/8th cup of marshmallows in each mug
Step-by-step explanation:
In order to split up the 1/2 cup of marhsmallows into 4 cups, you have to divide.
To divide, 1/2 by 4, you have to multiply 1/2 by the reciprocal of 4, which is 1/4.
1/2 x 1/4 = 1/8
The answer is a=7 because you have to do 7-6 which equals to 2 which a=7 is the right answer
Here y=1/2 x=pi/3=60°
y=cosx
1/2=cos60° and cos60°=1/2
so LHS=RHS
so that point is on curve y=cosx
