Answer:
w=-13/4
w=2
Step-by-step explanation:
|8w+5|=21
Step by step solution :
STEP
1
:
Rearrange this Absolute Value Equation
Absolute value equalitiy entered
|8w+5| = 21
STEP
2
:
Clear the Absolute Value Bars
Clear the absolute-value bars by splitting the equation into its two cases, one for the Positive case and the other for the Negative case.
The Absolute Value term is |8w+5|
For the Negative case we'll use -(8w+5)
For the Positive case we'll use (8w+5)
STEP
3
:
Solve the Negative Case
-(8w+5) = 21
Multiply
-8w-5 = 21
Rearrange and Add up
-8w = 26
Divide both sides by 8
-w = (13/4)
Multiply both sides by (-1)
w = -(13/4)
Which is the solution for the Negative Case
STEP
4
:
Solve the Positive Case
(8w+5) = 21
Rearrange and Add up
8w = 16
Divide both sides by 8
w = 2
Which is the solution for the Positive Case
STEP
5
:
Wrap up the solution
w=-13/4
w=2
8 x (3^2/4^2)
=4.5

The coordinates (x,y) are (3,2), If the graphs of
and
are intersect.
Step-by-step explanation:
The given is,
.................................(1)
....................................(2)
Step:1
The values of x and y are obtained by elimination method,
Substrate the equation (1) and (2),


( - )
Equation becomes,





From the equation (1),






Step:2
Check for solution,
....................................(2)
Substitute the values of x = 3 and y = 2 in above equation,



Both sides are equal, so the x = 3 and y = 2 is correct answer
Result:
The coordinates (x,y) are (3,2), If the graphs of
and
are intersect.
The value of Y is equal to 6.
The answer is 50. I have the same question and it makes no sense. The r= and the d= are supposed to have answers, but I’m not sure how you get them
