Factoring \:  is  \: the  \: easiest \:  way   \\  2 {x}^{2}  + 12x = 0 \\ \Leftrightarrow 2x(x + 6) = 0 \\ \Leftrightarrow x = 0 \: \vee \: x =  - 6

SCORPION-xisa [38]

Answer:

Therefore a numeric equation using negatives can be written as

   -11.94  = -1.94x  \therefore x =  \frac{-11.94}{-1.99}  = 6\hspace{0.1cm}days

Step-by-step explanation:

i) Amount <u>owed</u> by Steve = $11.94

ii) For every large coffee Steve has a <u>debit</u> of $1.99 applied to his account

iii) Let x be the number of days it has been since Steve last paid his bill.

    therefore a numeric equation using negatives can be written as

   -11.94  = -1.94x  \therefore x =  \frac{-11.94}{-1.99}  = 6\hspace{0.1cm}days.

Equivalent ratio for 12/9
Oliga [24]
In order to make a fraction a ratio, you must simplify it if it is needed. So for 12/9, you can divide 3 from the numerator and denominator. That would equal 4/3. Now that it is simplified, you can make it into a ratio. (can be using ":" or using the word "to") 
One way it can be used is --> 4:3
Another way --> 4 to 3 
Good luck!

Exponential Function:
vovangra [49]

Answer:

See below

Step-by-step explanation:

<em>On the graphs we see transformations of exponential functions</em>

<h3>Graphic 1 = Horizontal shift </h3>
  • f(x) = 2ˣ is the parent function
  • g(x) = 2ˣ⁺³ indicates shift to the left by 3 units
  • h(x) = 2ˣ⁻¹ indicates the shift to the right by 1 unit
<h3>Graphic 2 =Vertical shift</h3>
  • p(x) = (1/3)ˣ is the parent function
  • r(x) = (1/3)ˣ⁺³ indicates shift up by 3 units
  • q(x) = (1/3)ˣ⁻² indicates the shift down by 2 units
