Answer:
D
Step-by-step explanation:
As you look at the domain, which is going side to side,you can see there is not a definate end to the line which means that it is all real numbers which then whittles down your answer to either C or D.
when you look at the range, the up and down of it, you can see that it stops at -8 which is also the lowest point on the graph in the y-axis. since -8 is the smallest point for the range, then the Y would be greater than or equal to for the first part, which means it would be either A or D.
as you look at both answers to the questions, they only have D in common which means D is the answer.

Answer:
D
Step-by-step explanation:
Given y varies directly as x and z then the equation relating them is
y = kxz ← k is the constant of variation
To find k use the condition y = 
when x = 1 and z = 4 , then
= k × 1 × 4 = 4k ( divide both sides by 4 )
= k
y = xz ← equation of variation
When x = 6 and z = 3 , then
y = × 6 × 3 = × 18 = 2 × 6 = 12
Answer:
This is an isosceles triangle.
Step-by-step explanation:
An isosceles triangle is a triangle with 2 sides of equal length. A scalene triangle is a triangle where all sides have different lengths. An equilateral triangle is where all sides are exactly the same length. Only two of the sides are the same, therefore, this is an isosceles triangle.
