It’s option 1: 30 + 22i
Molodets [167]3 years ago
5 0

Answer:

(1) <em>30 + 22i </em>

Step-by-step explanation:

x = 3 + 7i ⇒ 2x = 6 + 14i

y = - 6 - 2i ⇒ 4y = - 24 - 8i

2x - 8y = ( 6 + 14i ) - ( - 24 - 8i ) = 6 + 14i + 24 + 8i = (6 + 24) + (14i + 8i )

2x - 8y = <em>30 + 22i</em>

Mamont248 [21]

Answer:$17.40  


Step-by-step explanation:

30% is the price that remains. Change that into a fraction 30/100 and then multiply the original cost

30/100*58=17.4

The answer is $17.40

Gabrielle sees a 30% discount on potted plants at the nursery. She chooses 3 potted plants whose regular prices are $3.59, $4.25
malfutka [58]

Using proportions, it is found that she will pay $8.28 in total after the discount.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three.

Before tax, the total price is given by:

P = 3.59 + 4.25 + 3.99 = $11.83.

She gets a 30% discount, hence the proportion she pays is 70% of this amount, hence:

P = 0.7 x 11.83 = $8.28.

She will pay $8.28 in total after the discount.
