Answer: (10 - 6i)/5

(x + yi) + (4(x + yi) + 6i) = 10

⇔ 5(x + yi) + 6i = 10

⇔ 5(x + yi) = 10 - 6i

⇔ x + yi = (10 - 6i)/5

(9x2 + 10x + 4) − (9x2 + 5x − 1)
ch4aika [34]

For this case we must simplify the following expression:

(9x ^ 2 + 10x + 4) - (9x ^ 2 + 5x-1)

We eliminate the parentheses taking into account that:

- * + = -\\- * - = +\\9x ^ 2 + 10x + 4-9x ^ 2-5x + 1 =

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

9x ^ 2-9x ^ 2 + 10x-5x + 4 + 1 =\\5x + 5

Answer:

5x + 5

Which one of the quotients is correct? A) 876 ÷ 43 = 20r17B) 876 ÷ 43 = 20r16C) 876 ÷ 43 = 20r7D) 876 ÷ 43 = 20r6
Olegator [25]

To check which of the quotients is correct, multiply 43 times 20 and add the remainder. The result must be equal to 876.

First, notice that 20 times 43 equals 860.

A)

The remainder is 17. 860 + 17 = 877, which is not equal to 876.

B)

The remainder is 16. 860 + 16 = 876, which is equal to 876.

C)

The remander is 7. 860 + 7 = 867, which is not equal to 876.

D)

The remainder is 6. 860 + 6 = 866, which is not equal to 876.

Since 20*43 + 16 = 876, then the correct quotient is shown in option B:

876 ÷ 43 = 20 r 16
