Write an equation of the line that passes through the point (6,-2) and is perpendicular to the line 6x+y=2
Scilla [17]

Answer:

y=2x-14

Step-by-step explanation:

Gradient as m(for 1st line m1 and m2 for 2nd line)

m1/m2=-1

m1=(-1)*(-2)=2

y-(-2)/x-6=2

y+2/x-6=2

y+2=2x-12

y=2x-14

PLEASE ANSWER WITH SOLUTION PLS
katen-ka-za [31]

Answer:

whatever% of anything, is just (whatever/100) * anything.

there were a total of 560000 votes, now, off those some are valid and some are invalid.

we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.

how many are the valid ones anyway?  well, 85% of 560000, which is just (85/100) * 560000.

we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?

well, (75/100) * [ (85/100) * 560000 ].

Find the distance from point A to the given line:<br> A(-1, 7), y=3x<br><br> How do I solve this?
kipiarov [429]

he formula of a distance between a point (a, b)

and a line Ax + By + C = 0:

d=\dfrac{|Aa+Bb+C|}{\sqrt{A^2+B^2}}

We have the point A(-1, 7) → a = -1, b = 7

and the line y = 3x → 3x - y = 0 → A = 3, B = -1, C = 0.

Substitute:

d=\dfrac{|(3)(-1)+(-1)(7)+0|}{\sqrt{3^2+(-1)^2}}=\dfrac{|-3-7|}{\sqrt{9+1}}=\dfrac{|-10|}{\sqrt{10}}=\dfrac{10\sqrt{10}}{\sqrt{10}\cdot\sqrt{10}}\\\\=\dfrac{10\sqrt{10}}{10}=\sqrt{10}

<h3>Answer: d = √10</h3>

HELP URGENTLY 1 QUESTION PLEASE SUPER QUICC
Zepler [3.9K]

So the formula for the area of a triangle is A=\frac{1}{2} bh (b = base, h = height). In this case, by counting from (-3,-3) to (-3,2) the height is 5 and the base is 4 counting from (-3,2) to (1,2).


Using this info, we can form the equationA=\frac{1}{2} *4*5 and solve from there.


A=\frac{1}{2} *4*5\\ A=\frac{1}{2} *20\\ A=10
