Answer: 3/5 or 0.6
Step-by-step explanation:
5c + 16.5 = 13.5 + 10c
-5c -5c
16.5 = 13.5 + 5c
-13.5 -13.5
3 = 5c
3/5 = 5c/5
0.6 = 5
Answer:
see the explanation
Step-by-step explanation:
Find out the equation of each line of the piece wise
<em>First line</em>
The first line has an open circle at (negative 2, negative 2) and it continues horizontally to an open circle (negative 5, negative 2)
(-2,-2) to (-5,-2)


<em>Second line</em>
The second line has a closed circle at (negative 2, 0) and then continues up to an open circle at (1, 1.5)
[-2,0] to (1,1.5)
<u><em>Find the slope</em></u>

<u><em>Equation in point slope form</em></u>

we have


substitute

<u><em>Convert to slope intercept form</em></u>

so


<em>Third line</em>
The third line has a closed circle at (1, 4) and continues down to open circle (5, negative 4). Which functions represent a piece of the function?
[1,4] to (5,-4)
The equation of the line is
---> Repeat all steps that in second line

therefore
The piece wise function is equal to
----> 
----> 
---> 
The question being the case, the equation is: 8x + 6y = 136.
Where x is the number of hours spent on job A and y is the number of house spent on job B. Now to solve for both variables.
Notice that if you add x and y, you should get a total of 20 hours so x + y = 20.
To get x, x = 20 - y. Replace the answer on the original equation gives you 8(20-y) + 6y = 136.
160 - 8y + 6y = 136
160 - 2y = 136
-2y = 136 - 160
-2y = -24
<span>Solve for y by dividing both sides of this equation by -2 to get y:
y = 12
Replace y on the x + y = 20 equation to get x.
x + 12 = 20
x = 20 = 12
x = 8
Therefore:
x = 8 hours on job A
y = 12 hours on job B
Hope this helps!</span>
Bisect typically means half but since we aren't given angle at the start so we can just have to solve for x.
(3x + 8) = (5x - 4)
3x = 5x - 12
-2x = -12
x = 6
Best of Luck!
