Select all the correct answers. Which operations involving complex numbers have solutions represented by point A on the graph? (4 + i) + 3(1 + i) (4 + i) − 3(1 + i) (4 + i) + (-3 − 3i) (4 + i) + (3 − 3i) (4 + i) − (3 + 3i)

the correct answer is $7.38

step-by-step explanation:

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.

answer: can you show the options ?

step-by-step explanation:

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
