Answer:
x = -2/15.
Step-by-step explanation:
Finding the second derivative:
f'(x) = 15x^2 +4x - 3
f"(x) = 30x + 4
30x + 4 = 0   for a point of inflection
x = -4/30 =  -2/15
So 30x + 4 is negative up to x =  -2/15 and positive thereafter.
So the curve passes from concave downward to concave upward at x = -2/15.
 
        
                    
             
        
        
        
Answer:

Step-by-step explanation:
Simply do 5 / 3 to get your answer. You can either say it is 5/3 or 1 2/3.
 
        
             
        
        
        
K so its an equation      546         x
                                   over   = over
                                   840       100
when u do cross multiplication it will be 840x=546 * 100
                                                       x is about 64%
Hope this is helpful
        
             
        
        
        
Use a let statement 
first
let x and x + 2 be the number so you write it like this
<u>let x = the first consecutive integer
</u><u>let x + 2 = the second consecutive integer
</u>
second
x(x+2)=323
x^2 + 2x = 323
        -323  -323
x^2 + 2x -323 = 0
third
try to factor -323 so it is 19 and -17
(x + 19) (x - 17) = 0
x = 19 
x = -17
hope this help
