In a year, the united states consumes about 146,000,000,000 gallons of gasoline. express this number in scientific notation. a) .146 x 1012 b) 1.46 x 1011 c) 14.6 x 1010 d) 146 x 109

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.  

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
