With every imaginary term, there are 2 complex conjugates with opposing signs. So if I had the term a+bi, the complex conjugate would be a-bi. So given your example of -1+4i, the complex conjugate would just be the opposite sign, now negative, to get -1-4i.

Let x be the number of pennies which is also equal to the number of dimes. By this representation, the number of quarters is equal 46 - 2x. The total amount is $4.87 or 487 cents. The equation that best represent the given is,
x + 10x + 25(46 - 2x) = 487
The value of x from the equation is 17. Therefore, there are 17 of both pennies and dimes and 12 quarters.
Answer:
The whole tank cost $55.13
Step-by-step explanation:
All you have to do is multiply the fraction and cost, to ge thte total cost
15 3/4 also equals 15.75 (it will be easier to multiply two fractions)
now each gall of the 15.75 costs 3.50 so we multiply the number of gallons by the cost
15.75 x 3.50 = 55.125
but now we must round since there isnt .125 cents
so
55.13 is the cost
