Find the value of d so the line that passes through (a, b) and (c, d) has a slope of 12. (Hint: Think about solving literal equations.) plzzz helpp

Which graph represents y=^3 sqrt x+8-3 ?

A) if $50000 is invested in a bank account that pays 9.3% of interest compounded on a six-monthly basis, how much money will be in the account after 3 and 12 years? b) if matusalen's father had put $2.0 in the bank when he was born and there, how long would matusalen have had to his death (969 years later) if the interest was 7% per year composed each month and weekly?
