Mathematics

Answer:

y = x - 3

3y = 2x + 3

y = -x - 1

Step-by-step explanation:

19. Slope = (1 - -2) / 6 - 3) =  1

y - y1 = 1(x - x1)

y - -2 = 1(x -  1)

y + 2 = x - 1   so y = x - 3 Answer

20.   slope =  2/3 and y intercept = 1  so its

y = 2/3x + 1

or  3y =  2x + 3

21.   Slope = -1 and y-intercept = -1, so its

y = -x - 1

Answer:

\boxed{\red{15 {x}^{2}  + 11xy - 12 {y}^{2}}}

Step-by-step explanation:

\blue{(5x - 3y)(3x + 4y)} \\ \blue{5x(3x + 4y) - 3y(3x + 4y)} \\ \blue{15 {x}^{2}  + 20xy - 9xy - 12 {y}^{2} } \\ \pink{=  15 {x}^{2}  + 11xy - 12 {y}^{2} }

How do you tell if a number is irrational or rational?
Korvikt [17]
A rational number is any number that can be expressed as a fraction
(ex: -5/2, 4 1/7, and 8/13)

An irrational number is any number that cannot be expressed as a fraction; a non-repeating, non-terminating decimal (ex: pi, 0.121231234...)

Hope this helps! :)
