Inverse variation is of the form y=k/x, or if you prefer yx=k.  "Inverse" variation because as x increases, y decreases...Anyway the equation can be expressed as:

y=k/x, we are given one point (10,8) so we can find the value of k, the constant of variation using those coordinates...

8=k/10  multiply both sides by 10

80=k so the equation is:

y=80/x

This stuff is kinda hard please help me find the answer
svlad2 [7]

Answer: 1 is D and 2 is B I think

Step-by-step explanation: 1 is D because 59.2 + (-84.7) because D is the same thing as 59.2-84.7, just written differently. 2 is B because the longer line resembles -15 and the smaller line resembles 6. -9 is circled because its supposed to add up to -9, hence why it would be 6+(-15)=-9. Hope this helped :)
