Answer:

y = x - 19

Step-by-step explanation:

Slope intercept form of a line is y = mx + b.

y = y-coordinate
m = slope
x = x-coordinate
b = y-intercept.

To find slope we use the formula $\frac{y_2-y_1}{x_2-x_1}$

$\frac{-11+6}{8-13}$
$-5/-5$
$1$

Now, to find the y-intercept we take the values of a point and plug them into our equation so far.

$-6=13+b$
$-6-13=13+b-13$
$b = -19$

Therefore, the answer is y = x - 19.

Softa [21]

Answer:

29.7

Step-by-step explanation:

The remaining distance is the total distance less the distance driven so far:

... 236.5 -69.4 -67.9 -69.5 = 29.7

In a continuous series, mean(x) = 80, assumed mean(A) = 60 and<br>EF=40 then find the value of EFd.

Aneli [31]

Using the given information, the value of Σfd is 800

<h3>Calculating mean using Assumed mean </h3>

From the question, we are to determine the value of Σfd

The formula for mean, using the assumed mean method is given by

$\bar x = A + \frac{\sum fd}{\sum f}$

Where $\bar x$ is the mean

A is the assumed mean

From the given information,

$\bar x = 80$

$A = 60$

$\sum f = 40$

Putting the parameters into the equation, we get

$80 = 60 + \frac{\sum fd}{40}$

$80-60 = \frac{\sum fd}{40}$

$20 = \frac{\sum fd}{40}$

$\sum fd = 20 \times 40$

$\sum fd = 800$

Hence, the value of Σfd is 800

Write a third-degree polynomial function whose zeros are 1, −3, and 4.

WARRIOR [948]

Recall that zeroes can be transformed into factors by subtracting them from x. This gives us the following factors:

(x - 1)(x + 3)(x - 4)

Now, if you multiply the first two factors together, you get the following:

(x² + 2x - 3)

Multiply that by the last factor, (x - 4), and you get this:

(x³ + 2x² - 3x - 4x² - 8x + 12)

This can be simplified:

(x³ - 2x² - 11x + 12)

And there's your final answer. Hope this helped!
