Answer:
A. (2, -1)
Step-by-step explanation:
(4x - 9) - x = -3
3x - 9 = - 3
3x = 6
x = 2
y = 4(2) - 9
y = 8 -9
y = - 1
(2, -1)
Check
-1 - 2 = -3
|2x + 1| < = 5
-5 < = 2x + 1 < = 5 ...subtract 1
-5 - 1 < = 2x + 1 - 1 < = 5 - 1
-6 < = 2x < = 4 ....divide by 2
-6/2 < = (2/2)x < = 4/2
-3 < = x < = 2
B. a number line with closed dots (because of the = sign) on -3 and 2 with shading in between
Since a sector is a fraction of a full circle, the ratio of a sector's area A to the circle is equal to the ratio of the __central angle__.
The proportion can be written as A/ πr² = ∅/ 2π.
Multiply both sides by πr² and simplify to get ∅/2 * r²
