Through: (-3,0), perp. to y = 3x - 1
Marrrta [24]

Answer:

y=-\dfrac{1}{3}x-1

Step-by-step explanation:

<u>Given: </u>

line y=3x-1

point (-3,0)

<u>Write:</u> equation of the line that is perpendicular to the given and passes through the point (-3,0)

<u>Solution:</u>

The slope of the given line is m=3

If m_1 is the slope of perpendicular line, then

m\cdot m_1=-1\\ \\3m_1=-1\\ \\m_1=-\dfrac{1}{3}

So, the equation of the needed line is y=-\dfrac{1}{3}x+b.

Find b. This line passes through the point (-3,0), so its coordinates satisfy the equation:

0=-\dfrac{1}{3}\cdot (-3)+b\\ \\0=1+b\\ \\b=-1\\ \\y=-\dfrac{1}{3}x-1

Fifteen times the square of a non-zero number is equal to 20 times number.What is the number? Its not 4/3
e-lub [12.9K]
The number is (2√3) / 3

To find the missing number, convert what it says in words to an equation:
15 {x}^{2}  = 20x
Divide both sides by 15:
{x}^{2}  =  \frac{20}{15}   \\  \\  {x}^{2}  =  \frac{4}{3}
Take the square root:
x =  \sqrt{ \frac{4}{3} }  \\  \\ x =  \frac{2}{ \sqrt{3} }  \\  \\ x =  \frac{2 \sqrt{3} }{3}
