Answer:

A

Step-by-step explanation:

observe

x² + 12x + y² + 10y = –45

add 36 + 25 on both side

x² + 12x + 36 + y² + 10y + 25 = –45 + 36 + 25 = 16

(x + 6)² + (y + 5)² = 16

SCORPION-xisa [38]

The equivalent expression of a + 5 is -(-a - 5)

<h3>How to rewrite the expression?</h3>

The expression is given as:

a + 5

-1 * -1 * (a + 5)

Open the bracket

-1 * (-a - 5)

This gives

-(-a - 5)

Hence, the equivalent expression of a + 5 is -(-a - 5)

What is the difference between the exact simple interest and the ordinary simple interest on a 200-day loan of 5,000 at 12%
77julia77 [94]

Answer:

  4.56

Step-by-step explanation:

"Ordinary" interest will be more than "exact" interest because the number of days in a year is a smaller value. The difference will be ...

  Io = Prt = 5000(0.12)(200/360) = 333.33

  Ie = Prt = 5000(0.12)(200/365) = 328.77

The difference is ...

  333.33 -328.77 = 4.56 . . . the difference in interest values

_____

<em>Additional comment</em>

The question asks for the difference between exact and ordinary interest, so the result is technically negative:

  328.77 -333.33 = -4.56
