Can someone solve and explain how to do these absolute equations for 40 points? I'll give brainliest to the best correct answer.
irga5000 [103]

Answer:

Explanation Below

Step-by-step explanation:

1.    -4 + | x - 1 | = 3

= -4 + | x - 1 | + 4 = 3 + 4

= | x - 1 | = 7

= x - 1 = -7     or    x - 1 = 7

= x = -6 or x = 8

2.   6 + 4 | 2x + 6| = 14

 = 6 + 4 | 2x + 6 | - 6 = 14 - 6

 = 4 | 2x + 6 | = 8

 = 4 | 2x + 6 | / 4 = 8/4

 = 2x + 6 = -2          or         2x + 6 = 2

 = x = -4    or     x = -2

3.  -10 + | -6 - x | = 1

  = -10 + | -6 + x | + 10 = 1 + 10

  = | -6 - x | = 11

  =  -6 - x = -11     or   -6 - x = 11

  = x = -17        or       x = 5

4.    | 7 - 2x | + 4 = 5

   = | 7 - 2x | + 4 - 4 = 5 - 4

   = | 7 - 2x | = 1

   = 7 - 2x = -1            or             7 - 2x = 1

   = x = 3       or   x = 4

Here are the Steps:

SOLVING EQUATIONS CONTAINING ABSOLUTE VALUE(S)

Step 1: Isolate the absolute value expression.

Step2: Set the quantity inside the absolute value notation equal to + and - the quantity on the other side of the equation.

Step 3: Solve for the unknown in both equations.

Step 4: Check your answer analytically or graphically.

16. Ajit borrowed 2,00.000 from a credit card company at 20% p.a. compounded quarterly.
Tcecarenko [31]

Given:

Principal value = 2,00,000

Rate of interest = 20% p.a. compounded quarterly.

To find:

The compound interest and the amount after one year.​

Solution:

Formula for amount is:

A=P\left(1+\dfrac{r}{n}\right)^{nt}

Where, P is principal, r is the rate of interest in decimal, n is the number of times interest compounded in an year and t is the number of years.

The interest is compounded quarterly. So, the value of n is 4.

Putting P=200000,\ r=0.2,\ n=4,\ t=1 in the above formula.

A=200000\left(1+\dfrac{0.2}{4}\right)^{4(1)}

A=200000\left(1+0.05\right)^{4}

A=200000\left(1.05\right)^{4}

A=200000(1.21550625)

A=243101.25

Therefore, the amount after one year is 2,43,101.25.

We know that the compound interest is the difference between amount and principal value. So,

C.I.=A-P

C.I.=2,43,101.25-2,00,000

C.I.=43,101.25

Therefore, the amount is 2,43,101.25 and the compound interest is 43,101.25.

Ramon bikes every afternoon. He travels 4 1/4 miles in 1/4 hour. At what rate dies Ramon ride his bike in miles per hour
Colt1911 [192]
1/4 hour = 4 1/4 miles

Change to improper fraction:
1/4 hour = 17/4 miles

Multiply by 4 on both sides:
1 hour = 17 miles

Answer: Ramon rides his bike at 17 miles/hour.
