Answer:
x = +3 and -3
Step-by-step explanation:
Start by solving for |x| as normal:
4 - |x| = 1
- |x| = -3 (subtract 4 from both sides)
|x| = 3 (multiply both sides by -1)
the absolute value of x means it will be positive, so you need to recognize that whatever is in the absolute value bars will be made positive.
this means that x = 3 AND -3, because both |3| and |-3| = 3
check your answer by plugging x = 3 and x = -3 back in:
4 - |3| = 1
4 - 3 = 1
1 = 1
and
4 - |-3| = 1
4 - 3 = 1
1 = 1
11 7/8 feet is the answer bc perimeter is just adding all the side, so if 2 side = 5 5/8 and the other 2 = 6 1/4 then the sum will be 11 7/8 feet

Answer:
Liz's annual pension is $1470
Step-by-step explanation:
Salaries for the last four years are $66,000; $66,000; $73,000; and $75,000
Finding the average salary in the four years will be;
Sum $66,000 + $66,000 + $73,000 + $75,000 =$280,000
Number of years =4
Average= $70,000
Applying 2.1 % pension
$70,000 * 2.1/100 =$1470 annual pension
Answer:
i = 4.68698 % to five decimal places.
Step-by-step explanation:
Let
i = annual rate of return
t = number of years = 4
using the compound interest formula,
12382500 = 10309500 (1+i)^4
rearrange
(1+i)^4 = 12382500 / 10309500
take log on both sides,
4log(1+i) = log(12382500 / 10309500)
solve for i
log(1+i) = (1/4)log(12382500 / 10309500)
1+i = e^((1/4)log(12382500 / 10309500))
i = e^((1/4)log(12382500 / 10309500)) -1
i = 0.0468698287401117
