What is the y-intercept of the line described by the equation below?
gtnhenbr [62]

Answer:

<h2>A. (0, 8)</h2>

Step-by-step explanation:

The slope-intercept form of an equation of a line:

<em>y = mx + b</em>

<em>m</em> - slope

<em>b</em> - y-intercept → (0, b)

We have the equation <em>y = 6x + 8</em>. Therefore

<em>m = 6</em>

<em>b = 8</em>

Complete the steps to factor the polynomial by grouping.<br>P(x) = x3 + 5x2 – x – 5
ahrayia [7]
<span>P(x) = x</span>³<span> + 5x</span>²<span> – x – 5

P(x) = x</span>²(x+5) - (x + 5)

P(x) = (x + 5)(x² - 1)

P(x) = (x + 5) (x + 1)(x -1)

What are the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2? x = (
Crank

The x =0 and y = 1 are coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2.

<h2>We have to determine</h2>

What are the x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2?

<h3>According to the question</h3>

A line segment at points A(2, -3) and B (-4, 9).

The x- and y- coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2 is given by;

\rm x=\dfrac{m}{(m+n)} [x_2- x_1]+ x_1 \\&#10;\\&#10; y=\dfrac{m}{(m+n)} [y_2- y_1]+ y_1 \\&#10;\\

Where \rm x_1 = 2 , \ x_2 =-4, \ y_1 =-3, \ y_2 = 9

Substitute all the values in the formula;

\rm x=\dfrac{m}{(m+n)} [x_2- x_1]+ x_1 \\\\

\rm x=\dfrac{1}{(1+2)} [-4-(2)]+ (2)\\\\ x = \dfrac{1}{3} \times (-6) +2 \\&#10;\\&#10;x = -2+2\\&#10;\\&#10;x=0

\rm y=\dfrac{m}{(m+n)} [y_2- y_1]+ y_1 \\\\ y=\dfrac{1}{(1+2)} [9-(-3)]+ (-3)\\\\&#10;y = \dfrac{1}{3} \times (12) -3\\&#10;\\&#10;y = 4-3\\&#10;\\&#10;y =1

Hence, the x =0 and y = 1 are coordinates of point E, which partitions the directed line segment from A to B into a ratio of 1:2.

Match each percent expression to its simplified form.
yulyashka [42]

Answer:

Step-by-step explanation:

1) 15% of 75 = (15/100) * 75 = 0.15*75 = 11.25

2) 7%  of 980 = 0.07 * 980 = 68.6

3) 45%of 62 = 0.45 * 62 =  27.9

4) 22% of 198 = 0.22 * 198 = 43.56
