Choose the equation that models the following statement: The current, I amps, produced by a battery is inversely proportional to
Anika [276]
By definition we have to:
 V = I * R
 Where,
 V: Voltage.
 I: Current.
 R: Resistance.
 The current, I amps, produced by a battery is inversely proportional to the resistance, R ohms. Clearing I have:
 I = V / R
 rewriting:
 I = V * (1 / R)
 answer:
 The equation that models the statement is:
 I = V * (1 / R)

Answer:

A. x = 5, -3

Step-by-step explanation:

<em><u>The quadratic equation/formula is:</u></em>

<em><u /></em>x = \frac{-b+- \sqrt{b^2 - 4ac} }{2a}

<em><u>The setup is:</u></em>

<em><u /></em>ax^2+bx+c=0

4x^2 - 8x -60=0

<em><u>Plug in the numbers according to the letter associated:</u></em>

<em><u /></em>x = \frac{8+-\sqrt{-8^2-4(4)(-60)} }{2(4)}

x = \frac{8+-\sqrt{1024} }{8}

x = \frac{8+-32}{8}

<em><u>Solve for addition and subtraction:</u></em>

<em><u /></em>x = \frac{8+32}{8}                                                                              x = \frac{8-32}{8}

x = \frac{40}{8}                                                                                  x = \frac{-24}{8}

x = 5                                                                                      x = -3

Help Solve and graph |-8x|&lt;8<br> which is it
seraphim [82]

Answer:

The correct option is B.

Step-by-step explanation:

We know, from the definition of |x|,

|-8x| = - 8x, when - 8x ≥ 0 i.e. x ≤ 0 ......... (1)

and |-8x| = 8x, when  - 8x < 0 i.e. x > 0 .......... (2)

Now, for x ≤ 0 {i.e. condition (1)}

- 8x ≤ 8, ⇒ x ≥ - 1 ......... (3)

Again, for x > 0 { i.e. condition (2)}

8x ≤ 8, ⇒ x ≤ 1 .......... (4)

So, combining conditions (3) and (4) we get  -1 ≤ x ≤ 1.

So, the correct option is B. (Answer)
