What is the area of a triangle with vertices at (5,0), (-3,1) and (2,6)? 6 units squared
54 units squared
22.5 units squared
36.5 units squared

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

its 4 because 2 times 2 is 4, if you double the number two you get four

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
