Answer:
Step-by-step explanation:
When y varies directly with x
y=kx x=20 y=-8
k=y/x
k=-8/20
k=-0.4
now when x=-4 find y
y=kx
y=-0.4*-4
y=1.6
Answer: 34
Step-by-step explanation: B=10 S1=12 S2=12. Add them up
You have to use the distance formula
which is:√(x2-x1)+ (y2-y1) (btw the whole equation is under the square root)
√(10- (-4) + (-2)- (-4)
√14+2
√16
4
