I think it is A because, 3 1/4 is divided into 3/4 and has a "remainder" of 1/4

This question has two parts. Be sure to answer both parts of the question. One inequality in a system is shown below. -12x + 3y

fgiga [73]

The inequality is -12x + 3y > 9.

PART A:

The sytem has no solution if inequality does not share a common area. The inequality -12x + 3y > 9 consist the region to left of line -12x + 3y = 9. So for no solution the region to left of equation -12x + 3y = 9 is suitable.

Thus inequality for no solution is, -12x + 3y < 9.

PART B:

For infinite solution the region of both inequality must overlap each other, or the inequality is same with some multiplication of divison factor. So inequality for infinite many solutions is,

$\begin{gathered} (-12x+3y>9)\times-1 \\ 12x-3y$

Thus inequality for infinite many solution is 12x - 3y < -9.

For what value of "a" will the product shown below have a purely imaginary value? (Show work please)

MakcuM [25]

If you expand out the brackets you get this,

(4+5i)(a+2i) = 4a + (5a)i + 8i - 10

The -10 comes from 5i * 2i.
Squaring i becomes -1.

Let's group the real stuff together,
and imaginary separately,

(4a - 10) + (5a + 8)i

For this to be purely imaginary,
the real part needs to be zero.

Therefore 4a - 10 = 0

Solve for a.
