The x-axis is defined by the equation y=0x+0. Since we see that our equation and that of the x-axis have the same slope, they will never intersect. So, to answer your question, any equation of the form y=b will have no x-intercept, except y=0, which will have infinitely many intercepts

Answer: r = -0.14

<u>Step-by-step explanation:</u>

$K=K_o\cdot e^{rn}\quad \text{where;}\\\bullet K\ \text{is the final amount of Kristinite}\\\bullet K_o\ \text{is the initial amount of Kristinite}\\\bullet r\ \text{is the rate of decay}\\\bullet n\ \text{is the number of seconds the decay has occurred}\\\\\\\text{Given:}\\\\K: \dfrac{1}{2}K_o\\\\r: unknown\\\\n: 2\\\\\\K=K_o\cdot e^{rn}\\\\\\\dfrac{1}{2}K_o=K_o\cdot e^{r(5)}\\\\\\\dfrac{1}{2}=e^{5r}\\\\\\ln\dfrac{1}{2}=5r\\\\\\\dfrac{ln\dfrac{1}{2}}{5}=r\\\\\\-0.14=r\\$
