Find the equation of the line passing through the points (3,-2) and (3, 4).The answer is x = 3. I'm just wondering how my textbo

ok got to this solution.My work:y-y1=m(x-x1). m=y2-y1 / x2-x1. y=mx+bm=4--2 / 3-3 = 6/0 = 0. m=0.y--2=0(x-3) = y=0-2 y=-2 <<<

Given two points. we can find the equation of a line passing through the points

The formula to be used is:

\frac{y_2-y_1}{x_2-x_!}=\frac{y-y_1}{x-x_!}

where

x_1=3,y_!=-2,x_2=3,y_2=4\frac{4-(-2)}{3-3}=\frac{y-(-2)}{x-3}

=>

\frac{6}{0}=\frac{y+2}{x-3}

The next step is to cross multiply

6(x-3)=0(y+2)

=>

6(x-3)=0

Divide both sides by 6 and make x the subject

x=3

Which of the following is the solution set of 18 - 3n + 2 = n + 20 - 4n?
exis [7]

The solution set of the equation is all reals ⇒ 3rd answer

Step-by-step explanation:

The solution set of an function is the set of all vales make the equation true. The equation has:

  • Solution if the left hand side is equal to the right hand side
  • No solution if the left hand side doesn't equal the right hand side

∵ The equation is 18 - 3n + 2 = n + 20 - 4n

- Add the like terms in each side

∴ (18 + 2) - 3n = (n - 4n) + 20

∴ 20 - 3n = -3n + 20

- Add 3n to both sides

∴ 20 = 20

In the equation of one variable, when we solve it if the variable is disappeared from the two sides, and the two sides of the equations are equal, then the variable can be any real numbers, if the two sides are not equal, then the variable couldn't be any value

∵ The the variable n is disappeared

∵ The left hand side = the right hand side

∴ n can be any real number

∴ The solution set of the equation is all real numbers

The solution set of the equation is all reals

Find the sum of the first 100 terms of the sequence below:<br> -19, -15, -11, -7, -3, ...<br> S100
ch4aika [34]

Answer:

17900

Step-by-step explanation:

First term a = -19

common difference d = -15-(-19) = 4

number of terms, n = 100

sum of first 100 terms,

n/2(2a+(n-1)d)

= 100/2(2×(-19)+(100-1)4)

= 50×(-38+99×4)

= 50×358

= 17900
