In order to write the equation of the line passing through the point (-2, 2) that is perpendicular to the line y = 2x + 3 , we must then find the perpendicular slope. What is the slope of any line perpendicular to line y = 2x + 3 ?

If f(x)=x^3 and g(x)=2x+7 when g(x)=-5

Can any one me with the answers to these questions asap?

It is saturday morning and jeremy has discovered he has a leak coming from the water heater in his attic. since plumbers charge extra to come out on the weekends, jeremy is planning to use buckets to catch the dripping water. he places a bucket under the drip and steps outside to walk the dog. in half an hour the bucket is 1/5 of the way full. what is the rate at which the water is leaking per hour?
