Answer:

$x=-\frac{5}{6}$

Step-by-step explanation:

Equation given: y=-6x-5.

In order to find zeros of an equation, substitute y=0 in the given equation.

0=-6x-5

-6x-5=0

-6x=5

$x=\frac{5}{-6}\\x=-\frac{5}{6}$

Therefore, $x=-\frac{5}{6}$ is zero for our given equation

Deborah hikes due south for 3 miles. She then turns due west and hikes 4 miles. What is the shortest distance between the starti

Cerrena [4.2K]

Answer:

5 miles

Step-by-step explanation:

The two legs of Deborah's hike form the right-angle legs of a right triangle. The shortest distance is then the hypotenuse of that triangle, found using the Pythagorean theorem.

d^2 = 3^2 + 4^2 = 9 +16 = 25

d = √25 = 5

Deborah ends 5 miles from her start.

Solve x2 - 8x - 9 = 0. Rewrite the equation so that it is of the form x2 + bx = c.

barxatty [35]

Answer:

x=9,-1 and $x^2+(-8)x=9$

Explanation:

we have been given with the quadratic equation $x^2-8x-9$

we compare the given quadratic equation with general quadratic equation

general quadratic is $ax^2+bx+c=0$

from given quadratic equation a=1,b= -8,c= -9

substituting these values in the formula for discriminant $D=b^{2}-4ac$

$D=(-8)^2-4(1)(-9)=100$

Now, to find the value of x

Formula is $x=\frac{-b\pm\sqrt{D}}{2a}$

Now, substituting the values we will get

$x=\frac{-(-8)\pm\sqrt{100}} {2}= \frac{8\pm10}{2}=9,-1$

And rewritting the given equation by shifting 9 to right hand side of the given equation and taking minus inside the bracket so as to convert it in the form of

$x^2+bx=c$
