3x + x - 4 + 100 = 180

4x + 96 = 180

4x = 180 - 96

4x = 84

\frac{4x}{4}  =  \frac{84}{4}

x = 21

A line passes through the given points. Write an equation for the line in point-slope form. Then rewrite the equation in slope-i
Andre45 [30]

Answer:

The answer to your question is  a)      y - 2 = -5(x - 3)  

                                                      b)     y = -5x + 17  

Step-by-step explanation:

Data

A (1, 12)

B (3, 2)

Process

1.- Find the slope

Formula

m = \frac{y2 - y1}{x2 - x1}

Substitution

m = \frac{2 - 12}{3 - 1} = \frac{-10}{2} = - 5

2.- Find the equation in point slope form

Equation

                             y - y1 = m(x - x1)

Substitution and equation

                           y - 2 = -5(x - 3)

3.- Find the slope-intercept form

Expand the point slope form

                           y - 2 = -5x + 15

Simplify

                           y = -5x + 15 + 2

Equation

                          y = -5x + 17

How to solve 2(x+y)^2-9(x+y)-5​
Aliun [14]

Answer:

2(x + y)² - 9( x + y ) -5 = 0

⇒2(x + y)² - 10 (x+y) +1(x+y) -5 = 0

⇒2(x+y)(x + y - 5 ) + 1(x + y -5 ) = 0

taking (x + y -5 ) common , 

⇒(x + y -5 )[2(x + y) + 1]  =0 

⇒(x + y -5)(2x + 2y +1) =0

hope , you got this
