The price of a new computer is $1,449 at your local store. This is 18% less than what it costs at the Brownstone Mall. How much
Komok [63]

Given:

Price of new computer at local store = $1,449

This is 18% less than what it costs at the Brownstone Mall.

To find:

The cost of new computer at the Brownstone Mall.

Solution:

Let x be the cost of new computer at the Brownstone Mall.

According to the question,

x-18\%\text{ of }x=1449

x-\dfrac{18}{100}x=1449

x-0.18x=1449

0.82x=1449

Divide both sides by 0.82.

x=\dfrac{1449}{0.82}

x=1767.07317

x\approx 1767.07

Therefore, the cost of new computer at the Brownstone Mall is $1767.07.

If –3 i is a root of the polynomial function f(x), which of the following must also be a root of f(x)? –3 – i –3i 3 – i 3i
Ber [7]

If -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)

<h3>How to determine the true statement?</h3>

The root of the polynomial function is given as:

-3 + i

The above root is a complex root.

If a polynomial has a complex root, then the conjugate of the root is also a root of the function

The conjugate of -3 + i is -3 - i

Hence, if -3 + i is a root of the polynomial function f(x), -3 - i must also be a root of f(x)
