The original line has the equation of y=-2x+8
enot [183]

The new equation of line that is perpendicular to the original that goes through the point (6, -1) in slope intercept form is y = \frac{1}{2}x - 4

<h3><u>Solution:</u></h3>

Given that original line has the equation of y = -2x + 8

We have to write a new equation that is perpendicular to the original that goes through the point (6, -1)

Let us first find slope of original line

<em><u>The slope intercept form of line is given as:</u></em>

y = mx + c ------ eqn 1

Where "m" is the slope of line and "c" is the y - intercept

On comparing the slope intercept form and given original equation, we get "m = -2"

Thus slope of original line "m" = -2

We know that product of slope of a line and slope of line perpendicular to it are always -1

slope of original line x slope of line perpendicular to it = -1

\begin{array}{l}{-2 \times \text { slope of line perpendicular to it }=-1} \\\\ {\text { slope of line perpendicular to it }=\frac{1}{2}}\end{array}

Let us find equation of line with slope m = 1/2 and passes through point (6, - 1)

Substitute m = \frac{1}{2} and (x, y) = (6, -1) in eqn 1

-1 = \frac{1}{2} \times 6 + c\\\\-1 = 3 + c\\\\c = -4

<em><u>Thus the required equation of line is:</u></em>

Substitute "c" = -4 and m = \frac{1}{2} in eqn 1

y = \frac{1}{2}x - 4

Thus the equation of line perpendicular to original line is found

7. Order the numbers from greatest to<br> least.<br> (12.012 12.001 12.102 12.01
Arada [10]

Answer:

12.102, 12.012, 12.01, 12.001

Step-by-step explanation:

Since all of the numbers have the same numbers in the tens and ones places, the first place we need to compare is the tenths. The number with the greatest digit in the tenths place is 12.102, so it is first. The other numbers have a zero in the tenths place, so we move to the hundredths. 12.012 and 12.01 both have a one in the hundreds place, so we need to look at the thousandths. 12.012 is greater because it has a two in the thousandths place instead of a zero like 12.01, so it goes next, then 12.01, leaving 12.001 as the least.

You have $9000 with which to build a rectangular enclosure with fencing. The fencing material costs $30 per meter. You also want
antoniya [11.8K]

Answer:i explained it

Step-by-step explanation:

The total cost of the fence will be 30(2L + 2W) + 2*25 W <= 9000

60L + 110W <= 9000

60 L <= 9000 - 110W

L <= 150 - 11/6 W

For a given width, the maximum area will correspond to the maximum length, so we can just go ahead and say L = 150 - 11/6 W

A = LW = (150 - 11/6 W) W

A = 150 W - 11/6 W2

A' = 150 - 11/3 W = 0

150 = 11/3 W

W = 450/11
