Use these complex numbers from the table to write the following expression as a complex number in standard form.

xxTIMURxx [149]

Answer:

= 5 − 101i

Step-by-step explanation:

2i(A ∙ E) − C + G

2i(-3 − 4i)(8 − 8i) − (13 + i) + (2 + 12i)

2i(-24 + 24i − 32i + 32i2) − (13 + i) + (2 + 12i)

2i(-24 − 8i − 32) − (13 + i) + (2 + 12i)

2i(-56 − 8i) − (13 + i) + (2 + 12i)

(-112i − 16i2) − (13 + i) + (2 + 12i)

(16 − 112i) − (13 + i) + (2 + 12i)

(16 − 112i) + (-13 − i) + (2 + 12i)

(16 − 13 + 2) + (-112i − i + 12i)

(16 − 13 + 2) + (-112 − 1 + 12)i

= 5 − 101i

Help me with these math questions.

Olegator [25]

graph A

no x-intercept

no y-intercept

H.A is y = 5

V. A. is x = 0

*****************************************

Answer: $\frac{150}{31}$

<u>Step by step explanation:</u>

log₆(5x + 6) - log₆(x - 4) = 2

log₆ $(\frac{5x+6}{x-4})$ = 2

$(\frac{5x+6}{x-4})$ = 6²

$(\frac{5x+6}{x-4})$ = 36

5x + 6 = 36(x - 4)

5x + 6 = 36x - 144

6 = 31x - 144

150 = 31x

$\frac{150}{31}$ = x

**********************************************************

Answers:

a. (-1, -5)
b. up
c. x = -1
d. $\frac{-2+\sqrt{15}}{3} and\frac{-2-\sqrt{15}}{3}$
e. -2
f. see attachment
g. domain (-∞, ∞) range [-5, ∞)

<u>Explanation:</u>

f(x) = 3x² + 6x - 2

a=3 b=6 c=-2

x = $\frac{-b}{2a} =\frac{-6}{2(3)} = \frac{-6}{6} = -1$

Axis Of Symmetry: x = -1

f(-1) = 3(-1)² + 6(-1) - 2

= 3 - 6 - 2

= -5

Vertex: (-1, -5)

x = $\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}$

= $\frac{-6+/-\sqrt{6^{2}-4(3)(-2)}}{2(3)}$

= $\frac{-6+/-\sqrt{36+24}}{6}$

= $\frac{-6+/-\sqrt{60}}{6}$

= $\frac{-6+/-2\sqrt{15}}{6}$

= $\frac{-2+/-\sqrt{15}}{3}$

x-intercepts: $\frac{-2+/-\sqrt{15}}{3}$
