In one quarter Stuart uses 2512 units of electricity. Part of his electricity bill is shown below. Units used = 2512 Cost of first x units at 12.86p per unit = £ Cost of remaining units at 11.8p per unit = £ Total cost of electricity used = £298 work out the number of units, at 12.86p per unit, that Stuart used. Give your answer to the nearest unit.

choice b is correct

step-by-step explanation:

we have been given the following system of inequalities;

we are required to graph the solution to the system of inequalities. using a graphing tool, the graph of the system is as shown in the attachment. the continuous line represents the graph of while the dotted line represents .

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)

i agree because i see the other persons thinking is clear
