Michele correctly solved a quadratic equation using the quadratic formula as shown below.

Fofino [41]

Answer:

The original equation must have been:

$7x^{2} -5x-2=0$

Step-by-step explanation:

A quadratic equation is in the form of :

$ax^{2} +bx+c=0$

And it is solved in the form of :

$x=\frac{-b+\sqrt{b^{-4ac} } }{2a}$ and $x=\frac{-b-\sqrt{b^{-4ac} } }{2a}$

Now the given equation is :

$x=\frac{-(-5)+-\sqrt{(-5)^{2} -4(7)(-2)} }{2(7)}$

We can see that here;

a = 7

b = -5

c = -2

So, the original equation must have been:

$7x^{2} -5x-2=0$

Nostrana [21]

Answer:

Step-by-step explanation:

The greater the magnitude of the leading coefficient, the narrower the parabola.

Widest: f(x) = 0.5x²

Next: f(x) = -x²

Jade hiked 1 1/4 miles on the trail. Gretta hiked 1 1/2 times as far on the trail as Jade. How far did Gretta hike on the trail?

Kryger [21]

Jade hiked 1 1/4 miles on the trail. Gretta hiked 1 1/2 times as far on the trail as Jade.

Jade hiked = $1\frac{1}{4}= \frac{5}{4} miles$

Gretta hiked = $[tex]1\frac{1}{2} becomes \frac{3}{2}$ [/tex] times Jade hiked

So Gretta hiked = $\frac{3}{2}*\frac{5}{4}$

To multiply two fractions, we multiply numerator with numerator and denominator with denominator

Gretta hiked = $\frac{15}{8}=1\frac{7}{8}$ miles
