Answer:
for second and third letters, we again have 26 combinations available and thus 26×26×26=17576 combinations for letters. But digits are from 0 to 9 i.e. 10 combinations for each place and tolal 10×10=100 combinations. Hence for LLLDD , we have 1,757,600 combinations available for license plates.
Step-by-step explanation:
Step-by-step explanation:
7x+3y=42.
y=-5x+30.
7x+3(-5x+30)=42
7x-15x+90=42
8x=42-90
-8x=-48
x=-48/-8
x=6
y=-5x+30
y=-5×6+30
=-30+30
y=0
(6,0)
4/5 and 40/50 are both equivalent
The quadratic has one root with multiplicity 2 if the discriminant is 0, which is
(That is, for a quadratic , the discriminant is .)
Set the discriminant equal to 0 and solve for :
