-2 -10x -4
Answer: 10x^3 + 29x^2 - 4
It would be 4/3 ant 6/7 is the best
The expression equivalent to given expression is 
<em><u>Solution:</u></em>
Given expression is:

We are asked to find the expression equivalent to given expression
Assume that denominator does not equal to zero
We can apply the exponent rule in given expression

Apply the above rule in given expression


Thus the equivalent expression is found
The slope-intercept form:

m - slope
b - y-intercept
We have m = 2 and b = 3. Substitute:

Answer:
-5
Step-by-step explanation:
15=-x+10
