Answer: D) 36 - 8i

Step-by-step explanation:

(5 - 3i)(6 + 2i)

= 5(6 + 2i) -3i(6 + 2i)

= 30 + 10i -18i - 6i²

= 30 - 8i -6(-1) reminder that i² = -1

= 30 - 8i + 6

= 36 - 8i

Answer:

x = 1 ⇔ y = -2.4

x = 2 ⇔ y = -1.8

x = 3 ⇔ y = -1.2

x = 4 ⇔ y = -0.6

Step-by-step explanation:

$3x-5y=15$

→ Rearrange to make y the subject

$-5y=-3x+15$

→ Multiply everything by -1

$5y=3x-15$

→ Divide everything by 5

$y=0.6x-3$

⇒ Substitute x = 1, 2, 3 and 4

$y=0.6x-3\\ y=(0.6*1)-3\\ y=0.6-3\\ y=-2.4\\(1,-2.4)$

$y=0.6x-3\\ y=(0.6*2)-3\\ y=1.2-3\\ y=-1.8\\(2,-1.8)$

$y=0.6x-3\\ y=(0.6*3)-3\\ y=1.8-3\\ y=-1.2\\(3,-1.2)$

$y=0.6x-3\\ y=(0.6*4)-3\\ y=2.4-3\\ y=-0.6\\(4,-0.6)$
