As points, x-intercepts take the form (x,0), so to find the intercepts we can set y=0 and solve for x.

x\ln(x+e)=0\implies\begin{cases}x=0\\\ln(x+e)=0\end{cases}

From the first equation alone, we already know that x=0 is a solution, which means one intercept is (0,0).

The second equation gives

\ln(x+e)=0\implies e^{\ln(x+e)}=e^0\implies x+e=1\implies x=1-e

so that the second intercept occurs at (1-e,0).

So if a=0 and b=1-e, we have a+b=1-e, giving C as the answer.

Whats the greatest ten you can multiply by 19 to get close to but not go over 684
USPshnik [31]

Answer:

The desired expression is  19 x (3 tens) = 19  x 30 = 570

So, the greatest ten   = 3 (tens)

Step-by-step explanation:

Let us check each tens.

19 x (1 ten)   = 19 x 10  = 190

19 x (2 tens) = 19 x 20  = 380

19 x (3 tens) = 19  x 30 = 570

19 x (4 tens)  = 19 x 40  =  760

But, here 760 is OVER the given term 684.

and 570 is the nearest value to the value 684.

So, the desired expression is  19 x (3 tens) = 19  x 30 = 570
