If (3-4i) (x+yi) = 1 + 0i. The value of x and y is (a). (3/25,4/25)
(b). (1/6,0)
(c). (1,1)
(d). (0.5)

Step-by-step explanation:

On rearranging the terms, we get:

Comparing both sides, we get:

Multiplying (i) by 4, we get:

Multiplying (ii) by 3, we get:

Adding equations (iii) and (iv), we get:

From (ii), we get:

Therefore:

★ Which is our required answer.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
