Answer:3x + 7y = 63
Explanation:The equation of PQ is
y = -(3/7)x + b
To find b, note that the line passes through the point (7,6). Therefore
6 = -(3/7)*7 + b
6 = -3 + b
b = 9
The equation of PQ is
y = - (3/7)x + 9
or
7y = -3x + 63
3x + 7y = 63
Answer
• Driving a more fuel-efficient car to eliminate “gas guzzling”
• Reducing heating needs
• Reducing lighting needs
Explanation
The three best strategies employed worldwide for conserving non-renewable energy resources are Reduce, Reuse and Recycle( 3R’s). Energy users are encouraged to increase reliance on renewable energies such as solar, wind and geothermal to aid in conserving the scarce fossil fuel that remain.
Walking and biking can be used as a strategy to cut down gas guzzling and manage the limited nonrenewable oil resources. One popular way of heating homes is oil heating. However, the conserve the oil, home owners are supposed to put up storm windows and insulate homes including caulking cracks around doors and windows to reduce heating costs. When using natural gas, users can reduce energy wasting by keeping the thermostat at 70 degrees and shutting off heat when not in use.
