Mama L [17]
I believe the correct answer from the choices listed above is option D. The statement that explains Karina's solution would be that the  cost of natural gas is $0.83 per unit. Her solution was y=0.83 where y represents the cost of the natural gas. Hope this answers the question.

Find the equation of the line.
mario62 [17]

Answer:

y = 2/3x - 7

Explanation:

First we must turn 3x + 2y = 6 to slope intercept form. In order to do this first subtract 3x on both sides of the equal sign, so we can get 2y by its self. Now we're left with 2y = -3x + 6 .

Next divide 2 from both sides to get y by its self. Now you got y = -3/2x + 3 (since 6 can be divided by 2 it's a 3 now) <u>Look above to see y= -3/2x +3 graphed</u>. ⤴⤴⤴

To find out the other equation we first need to know what its y-intercept is, and luckily for us we've already been given -3.

<u>Look above to see (6,-3) graphed</u>. ⤴⤴⤴

<u>Look above to see </u><u>both</u><u> </u><u>y = -3/2x + 3 </u><u>and</u><u> </u>

<u>y = 2/3x -7 graphed</u>. ⤴⤴⤴

This is a bit lengthy, but I hope you get it :)

Aliens have injected Ana with mathematical nanobots. These nanobots force Ana to think about math more and more. Initially, ther
natulia [17]

Answer:

<em>Math will take over Ana's brain at 4.4 hours</em>

Step-by-step explanation:

<u>Exponential Grow </u>

The population of the nanobots follows the equation  

p(t) = 5\cdot 2^t

We must find the value of t such that the population of nanobots is 106 or more, that is

5\cdot 2^t\geq 106

We'll solve the equation

5\cdot2^t= 106

Dividing by 5

2^t= 106/5=21.2

Taking logarithms

log(2^t)= log(21.2)

By logarithms property

t\cdot log(2)= log(21.2)

Solving for t

\displaystyle t=\frac{log21.2} {log2}

t=4.4 \ hours

Math will take over Ana's brain at 4.4 hours
