1. Simplify 3/2x to 3x/2
3x/2 + 5 + 5/x - 5
2. Collect like terms
3x/2 + (5 - 5) + 5/x
3. Simplify
3x/2 + 5/x
4. Cross multiply
3xx + 5 * 2/2x
5. Use "product rule"
3x^2 + 5 * 2/2x
6. Simplify 5 * 2 to 10
3x^2 + 10/2x
Assuming that you meant "(<span>3/2)x+5+5/x-5," group together the x terms and then group together the constant terms:
(3/2)x +5 - 5 + 5/x
This becomes (3/2)x + 5/x. You can leave your answer in this form, or you could sum up the 2 terms into one using the LCD 2x.
Then your </span>(3/2)x + 5/x becomes (2x)(3/2)x + (2x)(5/x)

Answer:
3.5
Step-by-step explanation:
From the graph,
x1 = 0
x2 = 4
y1 = 0
y2 = 14
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope
= ( 14 - 0 ) / ( 4 - 0 )
= 14 / 4
= 7 / 2
= 3.5
