Answer:
C {(-4, 2), (-2, 1), (2, 0), (4, 5)}
Step-by-step explanation:
The domain is the set of x-values for which the function is defined.
<h3>Choices</h3>
A) The relation is <em>only defined for x=2</em>. It is not a function, because x=2 maps to an infinite number of y-values.
B) The domain is an infinite number of x-values. The listed values are included in the domain, but they are <em>not the entire domain</em>.
C) The list of first-values in the ordered pairs is the domain of the function it matches the given domain.
D) The list of first-values in the ordered pairs is <em>not the same as the given domain</em>.
Answer:
y= -5.6

Answer:
The dimensions of rectangle are:
Step-by-step explanation:
Let 'l' be the length and 'w' be the width of the rectangle
- The length 'l' of the rectangle is 3ft less than twice the width 'w'.
so
Also, the area of the rectangle is 27ft^2.
As the area of the rectangle has the formula:
so
so the equation becomes
if
as the width can not be negative, so
ft
As
So the dimensions of rectangle are:
The answer is: [A]: ∡PQT and ∡TQS ; since this pair of angle add up to exactly 90°, AND form a right angle (90° angle).
