Answer:
24x² -19x-35= 0
24x² -(40-21)x -35= 0
24x²-40x+21x-35=0
8x(3x-5) +7(3x-5)=0
(3x-5) (8x+7)=0
(Ax-5)(2Bx+C) = (3x-5) (8x+7)
Comparing them,
A = 3
B = 4
C= 7
AB-3C = (3×4) - 3(7) = 12-21 = -9
The equation for finding the circumference of a circle:
If the radius of this circle is 1, then that means the diameter is 2. We multiply 2 by π to get our answer: 2π or approximately 6.283.
Make XY tables for each option.
If any of the Tables have identical X numbers it is not a function.
The first option has two X's that re 2, so is not a function.
Second option has 2 x's that are 4's, so is not a function.
The third option has no repeating X values so is a function.
The fourth option has two -2's and two 0's so ids not a function.
The function is the third choice:
On a coordinate plane, solid circles appear at the following points: (negative 3, 2), (negative 2, 2), (0, 1), (1, 3), (2, negative 4), (4, negative 1).
