Please find the perpendicular line slope equation please! Thanks!
lana66690 [7]

We need to convert this equation to slope-intercept form first.

We can do that by solving for y.

x - 5y = 15

<em><u>Add 5y to both sides.</u></em>

x = 5y + 15

<em><u>Subtract 15 from both sides.</u></em>

x - 15 = 5y

<em><u>Divide both sides by 5.</u></em>

y = 1/5x - 3

We now know the slope is 1/5.

The slope of the line perpendicular to the line with a slope of 1/5 is -5.

The slope of a perpendicular line is the negative reciprocal of the original slope.

Using a graphing calculator, we know the y-intercept of the line that is perpendicular to the original line must have a y-intercept of -6 to run through the points (-2, 5).

The equation of the new line is y = -5x - 6.

Simone measures the width of one of cardboard strip as 1/2 yard. A second cardboard strip measures 5/6 yard in width. Estimate t
Zepler [3.9K]

Answer:

The correct option is C. About 1 on the side with the 1 on top and 4 on the bottom yard.

Step-by-step explanation:

Consider the provided information.

Simone measures the width of one of cardboard strip as 1/2 yard.

A second cardboard strip measures 5/6 yard in width.

We need to find the combined width.

The combined width of the cardboard strip:

\frac{1}{2} + \frac{5}{6}=\frac{8}{6}=1\frac{1}{3}

1\frac{1}{3} is closer to1\frac{1}{4} as compare to 1\frac{1}{2}

Hence, the correct option is C. About 1 on the side with the 1 on top and 4 on the bottom yard.

Find the equation of the line. <br> Use exact numbers.
AlekseyPX
The slope of the line (m) = 3/1  = 3  
and the y intercept is at (0,3)  that is y = 3  so b = 3

using the slope intercept form y = mx + b

m = 3 and b = 3

so answer is y = 3x + 3

What is the measurement of each side of the perimeter is 94?
sveticcg [70]
2a+1 + 3a+2 +5a-9 you would start by combining like terms
2a+3a+5a= 10a
1+2-9= -6
10a-6=94
then subtract 94-6=88
then divide 88 by 10= 8.8
a=8.8

The angle measures of a triangle are in a ratio of 4 : 6 : 10. what type of triangle is this?
melomori [17]
4x+6x+10x=180

20x=180

x=9

So, the angles are:

4(9)=36
6(9)=54
10(9)=90

It's a right triangle.
