Find an equation for those points P such that the distance from P to A(0, 1, 2) is equal to the distance from P to B(6, 4, 2). W

suter [353]

Answer: The required equation for points P is $4x+2y=17.$

Step-by-step explanation: We are give two points A(0, 1, 2) and B(6, 4, 2).

To find the equation for points P such that the distance of P from both A and B are equal.

We know that the distance between two points R(a, b, c) and S(d, e, f) is given by

$RS=\sqrt{(d-a)^2+(e-b)^2+(f-c)^2}.$

Let the point P be represented by (x, y, z).

According to the given information, we have

$PA=PB\\\\\Rightarrow \sqrt{(x-0)^2+(y-1)^2+(z-2)^2}=\sqrt{(x-6)^2+(y-4)^2+(z-2)^2}\\\\\Rightarrow x^2+y^2-2y+1+z^2-4z+4=x^2-12x+36+y^2-8y+16+z^2-4z+4~~~~~~~[\textup{Squaring both sides}]\\\\\Rightarrow -2y+1=-12x-8y+52\\\\\Rightarrow 12x+6y=51\\\\\Rightarrow 4x+2y=17.$

Thus, the required equation for points P is $4x+2y=17.$

2/7x-23)+5x = 18 (x-1)

Blizzard [7]

Answer:

x= - 35 over 89

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

x−23+5x=18(x−1)

x+−23+5x=(18)(x)+(18)(−1)(Distribute)

x+−23+5x=18x+−18

(

x+5x)+(−23)=18x−18(Combine Like Terms)

x+−23=18x−1837

x−23=18x−18

Step 2: Subtract 18x from both sides.

x−23−18x=18x−18−18x

−89

x−23=−18

Step 3: Add 23 to both sides.

−89

x−23+23=−18+23

−89

x=5

Step 4: Multiply both sides by 7/(-89).
