What are the solutions for x when y is equal to 0 in the following quadratic

Mathematics
1 answer:
navik [9.2K]3 years ago
6 0

<u>Answer:</u>

The correct answer option is E) No solution.

<u>Step-by-step explanation:</u>

We are given the following quadratic equation which we are to solve for x when the value of y is 0:

y = x ^2+ 6x +12

x ^2+ 6x +12=0

Using the quadratic formula since there are no factors:

x=\frac{-b \pm \sqrt{b^2-4ac }}{2a}

Substituting the values in the formula to get:

x=\frac{-6 \pm \sqrt{6^2-4(1)(12) }}{2(1)}

x=-3+\sqrt{3}i or x=-3-\sqrt{3}i

There are no real number solutions to this quadratic equation.

navik [9.2K]

Answer:

If Lance got home from school at 3:32 p.m. A and B both represent:

A: seventeen minutes before 3 would be before 3 o'clock even happens

B: 28 minutes before 4 would make more sense, since 3:32 is before 4 o'clock

Lance got home 28 minutes before 4

Alberta Doan worked 6 hours at time-and-a-half pay and 3 ¼ hours at double-time pay. Her regular pay rate was $9.72 an hour. Wha
natka813 [3]

Answer:

Alberta's total overtime pay of the week was $ 145.80.

Step-by-step explanation:

Given that Alberta worked 6 hours at time-and-a-half pay, and 3 hours at double-time pay, and that the value of her regular work hour is $ 9.72, to determine the value of the pay of his overtime, the following equation must be performed:

6x1.5x9.72 + 3x2x9.72 = X

9x9.72 + 6x9.72 = X

87.48 + 58.32 = X

145.8 = X

Therefore, Alberta's total overtime pay of the week was $ 145.80.

A)<br> Identify all x-values not in the domain of<br> y=(x² – 4x²) / (3x² - 6x – 24)
True [87]

Answer:

x ≠ 4 or -2

Step-by-step explanation:

the denominator cannot be zero, so factor the bottom equation to get the zeros and those are the domain restrictions.

3x^2 - 6x - 24 ≠ 0

3(x^2 - 2x - 8) ≠ 0          (factor out a 3)

3(x - 4)(x + 2) ≠ 0            (factor equation)

x ≠ 4, x ≠ -2                     (use zero product property to find zeros)
