Observe o sistema de equações abaixo. {m − 3n = 16 {m + 5n= −8​ Quais são os valores de "m" e "n" que satisfazem esse sistema de equações? m = 1 e n = 3. m = 7 e n = -3. m = 52 e n = -12. m = -20 e n = -12.

Which statements are true? check all that apply. the line x = 0 is perpendicular to the line y = –3. all lines that are parallel to the y-axis are vertical lines. all lines that are perpendicular to the x-axis have a slope of 0. the equation of the line parallel to the x-axis that passes through the point (2, –6) is x = 2. the equation of the line perpendicular to the y-axis that passes through the point (–5, 1) is y = 1.

Y=(x+3)(x-4)(x+1)^2 sulutions? multiplicity?

One of the complementary angles is 4 degrees mor than the other. find the angles (recall that complementary angles are angles whose sum is 90 degrees.) which of the following can not be used to solve the problem if x represents one of the angles? a. 2x-4=90 b. 2x+4=90 c. x+4=90
