Which equation is correct for the perpendicular bisector of the line segment whose endpoints are (−1,1) and (7,−5)?
kherson [118]
Slope = (-5-1)/(7+1) = -6/8 = -3/4
Perpendicular slope = 4/3

Midpoint = ((-1+7)/2 , (1+(-5))/2) = (3, 3)

equation:
y = mx + c
y = 4/3 x + c

at point (3, 3)
3 = 4/3(3) + c
c = 3 - 4 = -1

y = 4/3 x - 1 or 3y = 4x - 3

LOL 3 more to gooo . find the value of x
garri49 [273]

Answer:

17

Step-by-step explanation:

These two angles add up to 180, so we can set up an equation. 5x-23+7x-1=180. Now we combine like variables, getting 12x-23-1=180. We add 23 to both sides, and get 12x-1=203. Then we add 1 to both sides, getting 12x=204. Finally we divide by 12 on both sides, with our result as x=17.

4x - 5y = -28<br>-3x - 2y = 10​
kozerog [31]

Answer:

y=-4/23

im not sure i didn't check (might be wrong)

Step-by-step explanation:

4x - 5y = -28

-3x - 2y = 10​

then make x the same

So

12x-15y=-84

-12x-8y=80

then its left with

-23y=-4

y=-4/23

find x by entering y into -3x - 2y = 10 and solving

Can someone help me with these 5 question I have attached?
Contact [7]

Example 2: x=10

Example 3: x=-1

Example 4: x=35

Example 5: a-b+c=9

Example 6: x=1, x=1/2

Further explanation:

<u>Example 2:</u>

\sqrt{4x-4} =6

Taking Square on both sides

(\sqrt{4x-4})^2 =(6)^2\\4x-4=36\\4x=36+4\\4x=40\\\frac{4x}{4}=\frac{40}{4}\\x=10

<u>Example 3:</u>

9+\sqrt{4x+8}=11

Subtracting 9 from both sides

9-9+\sqrt{4x+8}=11-9\\\sqrt{4x+8}=2\\

Taking Square on both sides

(\sqrt{4x+8})^2=(2)^2\\4x+8=4\\4x=4-8\\4x=-4\\\frac{4x}{4}=-\frac{4}{4}\\x=-1

<u>Example 4:</u>

8+\sqrt{x+1}=2

subtracting 8 from both sides

8-8+\sqrt{x+1}=2-8\\\sqrt{x+1}=-6

Taking Square on both sides

(\sqrt{x+1})^2=(-6)^2\\x+1=36\\

Subtracting 1 from both sides

x+1-1=36-1\\x=35

<u>Example 5:</u>

\sqrt{a-b+c}=3

Taking Square on both sides

(\sqrt{a-b+c})^2=(3)^2\\a-b+c=9\\

<u>Example 6:</u>

2\sqrt{2x-1}=4x-2

Taking square on both sides

(2\sqrt{2x-1})^2=(4x-2)^2\\4(2x-1)=16x^2+4-16x\\8x-4=16x^2-16x+4\\8x=16x^2-16x+4+4\\8x=16x^2-16x+8\\16x^2-16x-8x+8=0\\16x^2-24x+8=0

dividng whole equation by 8

2x^2-3x+1=0\\2x^2-2x-x+1=\\2x(x-1)-1(x-1)=0\\(2x-1)(x-1)=0\\2x-1=0 => x=\frac{1}{2}\\x-1=0 => x=1
