X and y vary inversely means y is inversely proportional to x, this means:
y=k/x, where k is a constant.
We are given that when x=-4, y=7/2, we replace these values to find k.
7/2=k/-4
k= (-4*7)/2=-14
So we have y=-14/x
Therefore, when x=4, y=-14/4= -7/2
Answer:
angle 1 + angle 2 = 100
angle 1 = 40
angle 2 = 60
angle 3 = 120
Step-by-step explanation:
Answer: -3/5
Step-by-step explanation: -3^3 is 27 and 5^3 is 125. So when you find the cube root of this equation you just simplify it to that.
B multiply 218 by 40 and you get 8,720
