How many 4 digit numbers are divisible by 5? This can be answered by thinking of the combinations of digits. For example, the first three digits could be anything from 100 to 999. There are 900 combinations, because 999-100 plus 1 (to count 999 in, subtracting counts the distance between) and numbers divisible by 5 end in a 5 or a 0, so 900 x2 for 2 combinations is 1800 numbers. Hope this helps!
Its the y intercept of function A is less than the y intercept of function b
D is equivalent because brackets don’t change anything here
CL will always be the same as LD, the CD line is perpendicular to AB where the L is, so, the extreme points of CD will always be in the same distance of L.
