Find an equation of the line passing through the point ( 6 , − 4 ) (6,-4) and perpendicular to 9 x − 3 y = 9 9x-3y=9 . Write you

MrMuchimi

Answer:

$y =-\frac{1}{3}-2$

Step-by-step explanation:

We are given;

A point (6, -4)
An equation of a line, 9x - 3y = 9

We are required to determine the equation a line passing through a point (6, -4) and perpendicular to the given line;

To answer the question we need to get the gradient of the given line first.
We write the equation 9x - 3y = 9 in the form of y = mx + c, where m is the slope;

That is;

y = 3x -3

Thus, the slope of the line is 3

But; m₁ × m₂ = -1 (For perpendicular lines)

Therefore;

m₂ = -1 ÷ 3

= -1/3

Therefore, the slope of the line in question is -1/3 and the line passes through (6, -4).

To get its equation, we get another point (x, y)

Then;

$\frac{y+4}{x-6}=\frac{-1}{3}$

Thus;

$3(y+4) = -1(x-6)\\3y + 12 = -x+6$

In the form of slope-intercept, the equation will be;

$3y = -x - 6\\y =-\frac{1}{3}-2$

Thus, the equation of the line is;

$y =-\frac{1}{3}-2$

What value is added to both sides of the equation x2 − 2x = 10 in order to solve by completing the square?

VLD [36.1K]

Hi,
Answer C

$x^2-2x=10\\
x^2-2x+1=10+1\\

\Rightarrow\ (x-1)^2=11\\
\Rightarrow\ (x-1)^2-11=0\\
\Rightarrow\ (x-1)^2-( \sqrt{11})^2=0\\
\Rightarrow\ ((x-1)+ \sqrt{11})((x-1)- \sqrt{11})=0\\
\Rightarrow\ x-1+ \sqrt{11}=0\ or\ x-1- \sqrt{11}=0\\

\Rightarrow\ x=1- \sqrt{11}\ or\ x=1+ \sqrt{11}\\

Shkiper50 [21]

Answer:

y = 57 - 3x

Step-by-step explanation:

Alice collected 57 skipping stones. And she skipped 3 stones a minute on her pond.

So. if y represents the number of stones left to her and x represents the number of minutes, then by the condition given we can write

y = 57 - 3x ..... (1)

So, this is equation of a straight line in the slope-intercept form. (Answer)
