Odette deposited $3,624.40 into a savings account with an interest rate of 2.1% compounded annual. about how long will it take for the account to be worth $7,000? a. 31 years, 9 months b. 30 years, 9 months c. 28 years, 4 months

7000 = 3624*(1+0.21)^x

7000 = 3624 *1.021^x

7000/3624 = 1.021^x

875/453 = 1.021^x

xlog(1.021 = log(875/453

x = 31.677

answer: (1,3) and (-2,0) i think.

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
