The function can be factorised to give x²(x²-5). Therefore the graph will touch the x axis at zero and cut it at -√5 and √5, giving three x-intercepts. To check, let's look at a graph my calculator drew of this function:
Step-by-step explanation:
Because a^m / a^n = a^(m-n),
we have 5³ / 5⁷ = 5^(3-7) = 5^(-4).
The answer is x = 3, as we know that the measure of vertical angles are equal. This means that 2x = x + 3, so x = 3.<span />

Hello!</h2>
The answer is: Tara is 24.6 miles from her starting point.
<h2>
Why?</h2>
Since she first drives to the north, and then to the east, we can find how far is Tara from her starting point by using the Pythagorean Theorem.
The Pythagorean Theorem states that:
Therefore,
So, Tara is 24.6 miles from her starting point and her displacement is 24.6 miles northeast.
