Is the relationship between the variables in this table a direct variation, an inverse variation, or neither. If it is a direct or inverse variation write a function to model it test all the points to verify your k value
x=2, 4, 6, 8
Y=1/3, 1/6, 1/9, 1/12

What is the domain and range of each function 1. x (3, 5, 7, 8, 11) y ( 6, 7, 7, 9, 14) 2. x (-3, -1, 2, 5, 7) y (9, 5, 4, -5, -7)

Arley is building a model of a city map. in one part of the city, three roads form a right triangle, which harley draws as triangle abc, with the following measures: m∠b=90° and m∠a=30°. in his scale model, the hypotenuse of triangle abc, ac¯¯¯¯¯¯¯¯, has a length of 817−−√ cm. what is the value of a (the length of bc¯¯¯¯¯¯¯¯)?

Solve this equation using substitution. {4x + y = −2} {4x + 6y = 44}
