C. For sure. Hope it helps
Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3
The missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²
How to find the distance between two coordinates?
The formula for distance between two coordinates is;
d = √[(y₂ - y₁)² + (x₂ - x₁)²]
where;
(x₁, y₁) is the coordinate of the first point
(x₂, y₂) is the coordinate of the second point
Now, this distance formula can also be rewritten when we square both sides to get;
(y₂ - y₁)² + (x₂ - x₁)² = d²
Thus, the missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²

Answer:
Independent
Step-by-step explanation:
Dependent Sampling:
Dependent sampling is one in which the individuals in one sample are used to determine the individuals in the other sample.
But the third dash graders are divided into two groups independent of each other.
So the sampling is independent.
It is qualitative because it is showing quality irrespective of the number of students .
Quantitative Sampling is one in which the results change with the number of the individuals / tests etc. But in this experiment the number of the students is fixed so it is showing quality rather than quantity.
