<u><em>There are two intersection points</em></u>
<u><em></em></u>
<u><em>Therefore</em></u>

<u><em>The solutions of the system of equations are the points and </em></u>
Answer: There is no x-intercept for this quadratic equation.
Step-by-step explanation:
An x-intercept is when the y-value of the point if equal to zero. There is no x-intercept for this quadratic equation. This can be supported by the fact that this equation cannot be factored.
B is true

Bacteria left in 1st hour=100*0.9¹=90
2st hour=100*0.9*0.9=100*0.9²
....
after 5 hours=100*0.9^5
No not all diagonal lines are lines of symmetry! Because if you take a piece of notebook paper and fold it in half the side do not match up! hope this helps :)
