Δstu is located at s (−3, 0), t (0, −3), and u (3, −3). which statement correctly classifies δstu? δstu is a scalene triangle.
δstu is an isosceles triangle.
δstu is an equilateral triangle.
δstu is a right triangle.

ΔSTU is a scalene triangle

Step-by-step explanation:

In order to find the type of triangle, we have to find the lengths of sides of the triangle.

The length can be calculated by using the distance formula:

So,

ST =

As we can see that the lengths of all sides are different, it can be concluded that the given triangle is a scalene triangle ..

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.
