Answer:

-6x^2+2x-4

Step-by-step explanation:

The given expression is;

\frac{12x^3-4x^2+8x}{-2x}

To simplify this expression, we either factor the numerator or share the denominator for each of the numerators.

Let us factor to obtain;

\frac{-2x(-6x^2+2x-4)}{-2x}

We cancel the common factor to obtain;

-6x^2+2x-4

The the intensity I of light (in lumens) in a certain lake at a depth of x feet is given by log(1/12) = -0.00235x. What is the i
ch4aika [34]

Answer:

11.45 lumens

Step-by-step explanation:

We are given that

log(I/12)=-0.00235x

Where x=Depth

I=Intensity of light

We have to find the intensity of the light at a depth of 20 feet.

Substitute the value of x

log(I/12)=-0.00235\times 20

log(I/12)=-0.047

\frac{I}{12}=e^{-0.047}

I=12e^{-0.047}

I=11.45 Lumens

Hence, the intensity of the light (in lumens) at a depth of 20 feet=11.45 lumens

Lauren is reading a novel for English class. The data below shows the number of pages reads, y, in x hours.
strojnjashka [21]

Answer:

Choice B is correct

Step-by-step explanation:

The variable x represents the number of hours;

2, 4, 5, 7, 9

The least value is 2 while the maximum value is 9. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 10. Choice A is incorrect since the values 7 and 9 will not be accommodated in the graph.

The y variable represents the number of pages read;

50, 100, 125, 175, 225

The least value is 50 while the maximum value is 225. The scale to be used must accommodate all these values. The scale can thus begin from 0 to 250. Both choices C and D are incorrect since none of the values will be accommodated in the graph.

Y=-0.72x + 7.7<br> Find y when x = 3.5.
OLEGan [10]

Answer:

y = 5.18

Step-by-step explanation:

replace x in the equation with 3.5

y = -0.72x + 7.7

y = -0.72(3.5) + 7.7

y = -2.52 + 7.7

y = 5.18
