Write an equation of the line that passes the points (-9,2) and is perpendicular to the line y=3x-12

If I’m correct use the slope −13 - 1 3 and a given point (−9,2) ( - 9 , 2 ) to substitute for x1 x 1 and y1 y 1 in the point-slope form y−y1=m(x−x1) y - y 1 = m ( x - x 1 ) , which is derived from the slope equation m=y2−y1x2−x1 m = y 2 - y 1 x 2 - x 1 .

What statements is equal to the expression p\11

V125BC [204]

Answer: "p divided by 11" or "p over 11" or "p by 11".

Step-by-step explanation:

We use mathematical statements to express any algebraic expression.

For example: We write 2x as "2 is multiplied by x " or " product of 2 and x".

p+q as "sum of p and q" or "p is added to q"

The given expression is : $\dfrac{p}{11}$

In mathematical statements, it can be written as "p divided by 11" or "p over 11" or "p by 11".

Hence, the statements are equal to the expression $\dfrac{p}{11}$ are "p divided by 11" or "p over 11" or "p by 11".

Sine, cosine, and tangent to calculate the height of the buildings in the diagram below.

DiKsa [7]

Answer: Around 68.0858 m

Step-by-step explanation:

Set the height of 37°-53°-90° triangle as x
Set the height of 50°-40°-90° triangle as y
The horizontal side both triangles share = 35

To find x To find y

$tan(37)=\frac{x}{35} \\\\35tan(37)=x\\\\x=26.37439...$ $tan(50)=\frac{y}{35} \\\\35tan(50)=y\\\\y=41.7113757...$

To find the height of the building, add the x-value and y-value:

$x+y=26.3744+41.7114=68.0858$

<em>I hope this is correct o_o</em>

Describe and correct the error in writing an equation of the line shown

Rudiy27

Answer:

$y = -\frac{3}{5}x+4$

Step-by-step explanation:

Given:

$(x_1,y_1) = (0,4)$

$(x_2,y_2) = (5,1)$

The attachment completes the question

From the attachment, the slope of the line was calculated as:

$m = \frac{1-4}{0-5}$

This step is inaccurate because the slope of a line is calculated using

$m = \frac{y_2-y_1}{x_2-x_1}$

Which gives

$m = \frac{1-4}{5-0}$

$m = \frac{-3}{5}$

$m = -\frac{3}{5}$

The line equation is then calculated using:

$y -y_1 = m(x - x_1)$

Substitute values for m, x1 and y1

$y - 4 = -\frac{3}{5}(x - 0)$

$y - 4 = -\frac{3}{5}(x)$

Open bracket

$y - 4 = -\frac{3}{5}x$

Make y the subject

$y = -\frac{3}{5}x+4$

I think the answer is 2^12

because ...

16^3 is equal to 4,096

and 2^12 is also equal to 4,096
