Someone, please help me! I"m on my last problem! The water-supply manager for Dallas needs to supply the city with at least 19 million gallons of potable water per day. The supply may be drawn from the local reservoir or from a pipeline to an adjacent town. The local reservoir has a maximum daily yield of 20 million gallons of potable water, and the pipeline has a maximum daily yield of 13 million gallons. By contract, the pipeline is required to supply a minimum of 7 million gallons per day. If the cost for 1 million gallons of reservoir water is $290 and the cost for 1 million gallons of pipeline water is $365, how much water should the manager get from each source to minimize daily water costs for the city? What is the minimum daily water cost?

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.

the answer is 40.
