Write (26 + 16i) − (26 − 7i) as a complex number in standard form. a. 52 − 9i b. 52 − 23i c. -9i d. 23i

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).

Choice D is  correct.

Step-by-step explanation:

(26+16i)-(26-7i)

Applying distributive law on the above expression we get

26+16i-26+7i

26-26+16i+7i

Adding coefficients of i and constant

0+23i

23i Which is the answer.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
