The correct answer for the problem shown in the figure atttached is the last option (option D), which is shown below:
D. (-3x+6i)(x+2i)
It is impotant to know that if you want to verify that the option D. (-3x+6i)(x+2i) is the correct answer, you can apply the distributive property to (-3x+6i)(x+2i).
Therefore, when you apply the distributive property, you obtain that the result is:
-3x²-12
Which is correct
Therefore, you can be sure that the correct answer is the option D. (-3x+6i)(x+2i).
22 is the answer because I just did it
So the two equations should be set up equal to each other.
1x + 8 = 2x - 4
now subtract 1x to 2x
8 = x - 4
now add 4 to 8
12 = x
to check you can plug it into x and see if they are both equal
12.3 or 12 3/10
4.5 + 7.8 = 12.3
or
4 10/20 + 7 16/20 = 11 26/20
11 26/20 can be simplified to 12 6/20 and further simplified to 12 3/10
y= (-5/2)x - 22
because 5x+2y=12 turns to y=(-5/2)x + 6 and the line parallel to it has to have the same slope so you have to just get the y intercept by plugging in -10 into the equation (-5/2)(-10)+?=3 and ?= -22.
