So for this, plug in 2 into the x variable and -3 into the y variable and solve.

$2+5(-3)=4\\ 2+(-15)=4\\ -13=4$

Since -13 = 4 is a false statement, (2,-3) is not a solution to this equation.

19. Seja 17x 51y+ 102. Qual é o valor de 9x 27y ? (A) 54 (B) 36 (C) 34 (D) 18 (E) indeterminado

Pergunta correta:

Seja 17x + 51y = 102. Qual é o valor de 9x + 27a? (A) 54 (B) 36 (C) 34 (D) 18 (E) indeterminado

Resposta: A) 54

Explicação passo a passo:

17x + 51y = 102 - - - - equação 1

Divulgue até 17

x + 3y = 6 - - - - - - - Equação 2

9x + 27y - - - - - - - equação 3

Comparando as equações 2 e 3

(Equação 3) = 9 × (equação 2)

Isso é, 9x + 27y = 9 × (x + 3y = 6)

9x + 27y = 9x + 27y = 54

Portanto ; 9x + 27y = 54

Determine whether each pair of lines is parallel, perpendicular, or neither.

natka813 [3]

There is no question.
For lines are parallel, graphs : they must have same gradients as every points. Geometry: prove using alternate angles, corresponding angles or interior angles
For lines are perpendicular, graphs: their gradients multiply to give -1. Geometry: they form a right angle
