7 - 9 = -2

reversed:

-2 + 9 = 7

hello, it is c -4

hope i you have a good day

the exponential expression to find the value of the cd, in dollars, after t years will be:  

step-by-step explanation:

formula of compound interest:   , where final value after years,   initial value, rate of interest in decimal and number of compounding in a year.

oliver plans to purchase a $1,500 certificate of deposit (cd) at his bank. that means,  

the cd will earn 2.3% interest, compounded semi-annually.

so,   and  

now, plugging these values into the above formula, we will

(rounded to the nearest ten-thousandth)

so, the exponential expression to find the value of the cd, in dollars, after t years will be:  

c minus thirteen equals negative two. to find c add thirteen two both sides. this cancels out the thirteen and gives you eleven on the other side. this leaves you with c equals eleven.
