NEED HELP NOW. I need help finding the x-intercepts.

Mathematics
1 answer:
Bingel [31]3 years ago
5 0

Answer:

To find the x-intercepts we can write:

0 = -1/2(x + 3)² + 4

0 = -1/2(x² + 6x + 9) + 4

0 = -1/2x² - 3x - 9/2 + 4

0 = -1/2x² - 3x - 1/2

0 = x² + 6x + 1

x = -3 ± 2√2 (use quadratic formula)

As a decimal this can be written as x = -5.83, x = -0.17.

The equation is:<br><br>Answer: the number of labor was :
Brilliant_brown [7]

Answer:

  • equation: 1368 = 380 +52x
  • labor hours: 19

Step-by-step explanation:

The desired equation will relate labor cost, parts cost, and total cost.

<h3>A.</h3>

The total cost is the sum of the parts cost and the product of labor hours and labor rate. We're told to use x to represent labor hours.

  total cost = part cost + (labor rate)(labor hours)

  1368 = 380 + 52x

__

<h3>B.</h3>

This equation can be solved in 2 steps:

  988 = 52x . . . . . . . step 1, subtract 380 from both sides

  19 = x . . . . . . . . . . step 2, divide both sides by the coefficient of x

The number of labor hours was 19.
