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
Answer:
x+y=15
Step-by-step explanation:
Given equation of 
Differentiating both side 

It passes through the point (12,3) so

So equation of tangent passing through (12,3) is
as 
So x+y =15 will be the equation of tangent which passes though the point (12,3)

Answer:D
Step-by-step explanation:
Answer:
Step-by-step explanation:
First one is 200 dollars for insurance which will be the constant and 15 dollars an hour which means the equation will be;
C = 15h +200 (Sinking Rivers)
Second one is $30 an hour and $110 for insurance which is the constant so he equation is;
C = 30h + 110 (Floating Down The Stream)
