Answer:

f(x)=x³-2x²+9x-18

Step-by-step explanation:

complex zeros always occur in pairs.

zeros are 2,3i,-3i

f(x)=(x-2)(x-3i)(x+3i)=(x-2)((x)^2-(3i)^2)

=(x-2)(x^2-9i^2)

=(x-2)(x^2+9)

=x^3-2x^2+9x-18

Answer:

A

Total before tax: $118

Total after tax: $102.66

Step-by-step explanation:

For A, we add the cost of the shirt and jeans to get the total before tax.

$39.20 + $79.80 = $118.00

For the total, after 13% we see how much 1% is.

1% of $118 is $1.18

$1.18 * 13 = $15.34.

$118 - $15.34 = $102.66

Hope this helped! Have a nice day :)

Two families go to a shake shack. The Johnsons order four fires and six cheeseburgers for $52. The Liauttads order three fries a
stira [4]

4 fries + 6 cheeseburgers = $52

3 fries + 2 cheeseburgers = $24

9 fries + 6 cheeseburgers = $24×3

= $72

$72-$52=$20

5 fries = $20

1 fries = $20÷5

= $4

1 cheeseburger = [$24 - (3×$4)]÷2

= $6

The graph shows a relationship between x and y.<br> What are the zeros of the function?
miv72 [106K]

Answer:

x = -3

x = -1

x = 2

Step-by-step explanation:

The <u>zeros of a function</u> are the x-values of the points at which the curve crosses the x-axis.

From inspection of the given graph, the curve crosses the x-axis at:

  • x = -3
  • x = -1
  • x = 2

Therefore, these are the zeros of the function.
