Write (26 + 16i) − (26 − 7i) as a complex number in standard form. A. 52 − 9i B. 52 − 23i C. -9i D. 23i
nikitadnepr [17]

Answer:

D.  23i.

Step-by-step explanation:

(26 + 16i) − (26 − 7i)

Using the distributive law this becomes:

26 + 16i - 26 + 7i

Adding like terms:

= 0 + 16i + 7i

= 23i  (answer).

Could someone find the expression?
KatRina [158]

Answer:

Total earned(in dollars) =2\ t+920

Step-by-step explanation:

Given:

Michael's hourly rate working as a tutor = $12 per hour

Michael's hourly rate working as a waiter = $10 per hour

Total number of hours worked by Michael for both jobs this month = 92

Let the number of hours Michael works as a tutor this month be =t hours.

∴ Number of hours Michael works as a waiter this month will be =(92-t) hours.

Amount earned by Michael this month from tutor job

⇒\textrm{Hourly rate}\times\textrm{Number of hours worked}

⇒12\times t

⇒\$12\ t

Amount earned by Michael this month from tutor job

⇒ \textrm{Hourly rate}\times\textrm{Number of hours worked}

⇒10\times (92-t)    

⇒\$(920-10\ t)     [Using distribution]

Total amount earned by Michael from both the jobs this month in dollars can be given as

⇒\textrm{Amount earned from tutor job+Amount earned from waiter job}

⇒12\ t+(920-10\ t)

⇒12\ t+920-10\ t

⇒2\ t+920

Which of the following is a solution to the equation y=-1/4x +8 O (10,8) 0 (48) O (49) O (-8.-10)​
Lyrx [107]

Answer:

Step-by-step explanation:

The last one -- D -- is the closest correct answer. None of them, however, is right.

y = -1/4 x + 8                      Let x = - 8

y = -1/4 * - 8   +  8              The standard rule is starting from the left, do the multiplication first then do the addition

- 1/4 * - 8 will first of all give you a positive result. When 2 minuses are multiplied they give a positive answer.

-1/4 * - 8 = 1/4 * 8

1/4 * 8 = 2

y = 2 + 8

y = 10

So the ordered pair (-8 , 10) is the answer.
