1.4.1 Study: Solving Absolute Value
|2x+1|+5 = 12

Step-by-step explanation

currently u should end up with 2x+1=7

3. now subtract one from both sides and you get 2x=6, then divide both sides by 2 and you get x=3

and if u substitute 3 for x back in the original you get 12

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
