Solve -8|4b-6|+9=-39

Mathematics
1 answer:
LUCKY_DIMON [66]3 years ago
7 0

Answer:

b=3                        b=0

Step-by-step explanation:

-8|4b-6|+9=-39

Subtract 9 from each side

-8|4b-6|+9-9=-39-9

-8 | 4b-6| = -48

Divide by -8

-8/-8 | 4b-6| = -48/-8

| 4b-6| = 6

When solving the absolute value, there is a positive and a negative solutions

4b-6  = 6      and 4b-6 = -6

Add 6 to each side

4b-6+6 =6+6     4b-6+6 = -6+6

4b =12                  4b = 0

Divide by 4

4b/4 =12/4            4b/4 = 0/4

b=3                        b=0

A software engineer has the capability of thinking 100 lines of code in five minutes and can type 100 lines of code in 10 minute
steposvetlana [31]

In one hour a software engineer will write 250 lines of code.

Given that, a software engineer has the capability of thinking 100 lines of code in five minutes and can type 100 lines of code in 10 minutes.

1st 5 minutes = He thinks the code

2nd 5 minutes = He writes the code

3rd 5 minutes =  Break

4th 5 minutes = Write [ because he can type up to 10 minutes if he thinks for 5 minutes ]

5th 5 minutes = Think [ He has completed 10 minutes of writing so he has to think ]

6th 5 minutes =  Break

7th 5 minutes = He writes the code

8th 5 minutes = He writes the code

9th 5 minutes = Break

10th 5 minutes = He thinks the code

11th 5 minutes = He writes the code

12th 5 minutes =  Rest [ he has completed his 10 minutes of working.

5 minutes thinking  + 5 minutes writing ]

Therefore, in one hour a software engineer will write 250 lines of code.

. Center at (-4,-1), radius = 2​
valkas [14]

Consider we need to find the equation of the circle.

Given:

The Center at (-4,-1), radius = 2​.

To find:

The equation of the circle.

Solution:

The standard form of a circle is

(x-h)^2+(y-k)^2=r^2

Where, (h,k) is the center of the circle and r is the radius of the circle.

Putting h=-4, k=-1 and r=2, we get

(x-(-4))^2+(y-(-1))^2=(2)^2

(x+4)^2+(y+1)^2=4

Therefore, the equation of the circle is (x+4)^2+(y+1)^2=4.
