Answer:
x = ±
Step-by-step explanation:
x² = 10 ( take square root of both sides )
x = ±
A quadratic equation has the general form
of: <span>
y=ax² + bx + c
It can be converted to the vertex form in order
to determine the vertex of the parabola. It has the standard form of:
y = a(x+h)² - k
This can be done by completing a square. The steps are as follows:
</span><span>y = 3x2 + 9x – 18
</span>y = 3(x2 <span>+ 3x) – 18
</span>y + 27/4= 3(x2 <span>+ 3x+ 9/4) – 18
</span>y = 3(x2 + 3/2)^2 – 99<span>/4
</span>
Therefore, the first step is to group terms with the variable x and factoring out the coefficient of x^2.

The rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute
<h3>Calculating Rate </h3>
From the question, we are to determine the rate which is equivalent to the rate Paula walked
Using the formula,
From the given information,
Distance = 1/12 mile
Time = 5/3 minutes
Putting the parameters into the formula, we get
mile/minute
Hence, the rate that is equivalent to the rate Paula walked is 1/20 mile/minute OR 0.05 mile/minute
