Answer:
Below.
Step-by-step explanation:
These are perpendicular line which intersect at (-4, -9).
Vertical line is x = -4.
Horizontal lone is y = -9.
The expression 3 + x = 11 is an equivalent equation of a model
The solution to the equation is x = 8
<h3>How to solve the equation</h3>
The equation is given as:
3 + x = 11
Subtract 3 from both sides of the equations
-3 + 3 + x = -3 + 11
Evaluate the expression on the right-hand side
-3 + 3 + x = 8
Evaluate the expression on the left-hand side
x = 8
Hence, the solution to the equation is x = 8

Answer:
A'(5, -3)
Step-by-step explanation:
Reflection over the x-axis changes the sign of the y-coordinate:
(x, y) ⇒ (x, -y)
A(5, 3) ⇒ A'(5, -3)
5 x (4 x 3) = (5 x 4) x 3
7 x (3 x 6) = (7 x 3) x 6
(30 x 5) x 12 = (30 x 12) x 5

Answer:
The correct option is C
Step-by-step explanation:
From the question we are told that
The number of independent variables is
The number of observation is
Since n is are independent variables then their degree of freedom is 3
The denominator(i.e z) degrees of freedom is evaluated as
So for the numerator (n) the degree of freedom is Df(n) = 3
So for the denominator(i.e z) the degree of freedom is Df(z) = 43
