It’s asking to write an equation of the line with a slope...please help!!
Vlada [557]

Answer:

y = -3/4x - 6

Step-by-step explanation:

Use y-intercept (0, -6) and slope -3/4 and put into y=mx+b form to solve for b

Remember that m is also known as slope!

-6=(-3/4 * 0) + b

b= -6

y= -3/4x - 6

Determine the roots of f(x) = -12-2.1x+18x^2-2.75x^3 graphically. in addition, determine the first root of the function with
vesna_86 [32]

The given function is that is a cubic polynomial

f(x)=-12-2.1x+18x^2-2.75x^3

when arranged in descending order that is from highest degree to lowest degree

f(x)=-2.75x^3+18x^2-2.1x-12

Since it is a three degree polynomial it has three roots.

According to rational root theorem , the possible roots of the above expression that is factors of  \frac{12}{2.75}=\frac{48}{11}  are \pm1, \pm 2, \pm 3, \pm 4, \pm 6, \pm 8, \pm 12, \pm 24, \pm 48, \pm\frac{1}{11}, \pm\frac{2}{11}, \pm\frac{3}{11}\pm\frac{4}{11}\pm\frac{6}{11},\pm\frac{8}{11},\pm\frac{12}{11}, \pm\frac{24}{11},\pm\frac{48}{11}

As you can see from the graph all roots of this polynomial are real.

The smallest positive root is 0.954 and smallest negative root are -0.724.

To find the mean add up all the numbers given then divide your answer by how many numbers there are.
for ex: 1,2,3,4,5
1+2+3+4+5= 15
15 divided by 5 = 3
so the mean is 3

Pile Y has the greater mean number of pages per book because it is 5 books less than pile W.

<h3>How to calculate greater mean number of pages?</h3>

From the complete information, we can deduce that the number of each pile of book is given as follows:

<u>For pile W;</u>

Red books = 10 × 5 = 50 red books.

Blue books = 5 × 5 = 25 blue books.

Therefore, total books in pile W = 50 + 25 = 75 books.

Mathematically, the mean for each pile can be calculated by using the following formula:

Mean = [F(x)]/n

Mean = 75/10

Mean = 7.5.

<u>For pile Y;</u>

Red books = 10 × 5 = 50 red books.

Mean = [F(x)]/n

Mean = 50/5

Mean = 10.

In conclusion, pile Y has the greater mean number of pages per book because it is 5 books less than pile W.
