Solve for x 1-6x=-17

Zarrin [17]

Answer:

x=3

Step-by-step explanation:

1. Rearrange terms

1 - 6x = -17

-6x + 1 = -17

2. Subtract 1 from both sides of the equation (we want to get rid of 1)

3. Simplify

In the end, you should get x=3.

Which shows the correct substitution of the values a, b, and c from the equation -2=-x+x^2-4 into the quadratic formula?

Greeley [361]

Given the equation:

(1) $-2=-x+ x^{2}-4$

We need to find a, b and c. So, we know that a quadratic equation is given by:

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

Then, we need to order the equation (1) and to adjust it to the equation (2), so:

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

So, if we compare these two equations, the conclusion is:

$a=1$
$b=-1$
$c=-2$

(3) $x= \frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$

Substituiting a, b and c into (3):

$x= \frac{-(-1)\pm \sqrt{(-1)^{2}-4(1)(-2)}}{2(1)}$

Finally, the results are two values:

$x_{1}=2$
$x_{2}=-1$

Aleks [24]

Answer:

The answer is C. 119.1

Step-by-step explanation:

The arch measure between Cole St. and Maple St. is 105 degrees which is equal to 7/24 of the circumference. since the diameter is given simply multiply the circumference by 7/24 which equals 285,887/2400. Divide these and you get your answer.
