2x^2 = 2

so x needs to equal 1 since 2*1 = 2

What is the slope of a line perpendicular to the line whose equation is 3x+6y=-183x+6y=−18. Fully reduce your answer.

schepotkina [342]

Answer:

Step-by-step explanation:

The given equation of line is

$3x+6y=-18$

We need to find the slope of a line which is perpendicular to the given line.

The given equation can be rewritten as

$3x+6y+18=0$ ...(i)

If a line is defined as $ax+bx+c=0$ , then the slope of the line is

$m=-\dfrac{a}{b}$

In equation (i), a=3, b=6 and c=18. So, slope of the line is

$m_1=-\dfrac{3}{6}=-\dfrac{1}{2}$

Let $m_2$ be the slope of perpendicular line.

We know that product of two perpendicular line is -1.

$m_1\cdot m_2=-1$

$(-\dfrac{1}{2})\cdot m_2=-1$

Multiply both sides by -2.

$m_2=2$

Therefore, the slope of perpendicular line is 2.

Write an equation in slope-intercept form where the slope is 5 and y-intercept is 3.

gogolik [260]

Y=mx + b
In this case:
m=slope=5
b=y-intercept=3
y=5x+3

Rewrite the following in ascending order.<br>9/25, 2/5, 14/-75, -19/10, 8/15

madam [21]

Step-by-step explanation:

Given numbers are 9/25 ,2/5, 14/-75, -19/10, 8/15

The denominators = 25 , 5, 75, 10, 15

LCM of the denominators = 150

9/25 = (9/25)×(6/6) = 54/150

2/5 = (2/5)×(30/30) = 60/150

14/-75 =(-14/75)×(2/2) = -28/150

-19/10 = (-19/10)×(15/15) = -285/150

8/15 = (8/15)×(10/10) = 80/150

Ascending order of the numbers

= -285/150, -28/150, 54/150, 60/150, 80/150

<em>-19/10, 14/-75, 9/25, 2/5, 8/15</em>

First find slope
(2-4)/(3+1) = -2/4 = -1/2
Use point (3,2)
y-y1 = m(x-x1)
Plug everything in
y-2 = -1/2(x-3)

Solution: A
