Answer:
B.(x, y)→(2.5x, 2.5y)
Step-by-step explanation:
Does the question have a radius
Answer:
(-7, -1), 6 units
Step-by-step explanation:
x² + y² + 14x + 2y + 14 = 0
x² + 14x + y² + 2y = -14
Complete the squares.
x² + 14x + 49 + y² + 2y + 1 = -14 + 49 + 1
(x + 7)² + (y + 1)² = 36
(x + 7)² + (y + 1)² = 6²
The center is at (-7, -1) and the radius is 6.
The values coming in the interval (-3,1] are -2, -1, 0, and 1.
<h3>What is defined as the term interval notations?</h3>
- An interval is represented on a number line using interval notation. In all other sayings, it is a method of writing real number line subsets.
- An interval is made up of numbers that fall between two specific data set.
- Intervals can be categorized according to the numbers in the set.
- Interval Open: The endpoints of a inequality are not included in this type of interval.
- Interval Closure; The endpoints of a inequality are included in this type of interval.
- Interval with Half-Open Doors: This interval contains only one of inequality's endpoints.
The given interval notation is;
(-3,1], it is the case of half open half close.
-3 comes with the open interval, it means its value will not be included in the interval.
1 is with the closed interval, it means its value will be included in the interval.
Thus, the values lying between the interval (-3, 1] are -2, -1, 0, and 1.

Answer:
As shown in picture, shaded space area:
A = outer rectangle area - inner rectangle area
= 11 x 8 - 9 x 6
= 88 - 54
= 34 (yd2)
Hope this helps!
