Anumber less 7 is greater than -45. how can the solutions for this inequality be described? is -40 a solution? a) all numbers less than -38.; yes b) all numbers greater than -38.; no c) all numbers less than or equal to -38.; yes d) all numbers greater than or equal to -38.; no

y=3x+4

step-by-step explanation:

given the points a(0,4) and b(-4, -8)

eqn of line ab: (y-4)/(x-0)=(-8-4)/(-4-0)

(y-4)/x=-12/-4=3

y=3x+4

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
