The equations would be
<span>Value: b + c = 19000
Interest: 0.07b + 0.09c = 1590
</span>0.07b + 0.09 (19,000 - b) = 1,590
0.07b + 1,710 - .09b = 1,590
<span>120 = .02b
</span>
B = 6,000
<span>C = 13,000
</span><span>
So the correct answer is </span><span>d. $6000 in bonds; $13,000 in certificates of deposit.

Thank you for posting your question. I hope that this answer helped you. Let me know if you need more help.
I think it would be $14 per book
65 yards 2 feet = ?
1 yard = 3 feet
65(3)+2= 195+2 = 197
it is 197 feet
<u>To prove the trigonometric equation:</u>


We know that
, substitute this in place of 1.

Multiply each term of the first term with each term of the 2nd term.

Group like terms together.



= LHS
RHS = LHS

Hence proved.
