Answer:

-2^{2} -4(1)(5)

so the answer would be c.

Step-by-step explanation:

The discriminant is the following equation:

b^{2} -4ac

You just simply plug in the values of the coefficients.

0=x^{2} -2x+5

a = 1 (first terms coefficient)

b = -2 (second terms coefficient)

c = 5 (last terms coefficient)

denis23 [38]
In centre is the centre of a circle that is inscribed in a triangle, called the incircle, i.e. circle is tangent to all three sides AND located inside the triangle.  An incircle is roughly sketched in the accompanying diagram.

Since all radii of an incircle are equal, we have
4x-1=6x-5
Solving for x,
6x-4x=5-1
x=2
consequently, distance from incentre to each side of the triangle is
4(2)-1=7
check 6x-5=6(2)-5=7... checks.

Answers:
The value of x = 2
The distance from incentre to side of triangle is 7

What is the domain and range of these two graphs .?
Vera_Pavlovna [14]

Answer:

5. D: (-4,3]  R: (5,-4] 7. D: (-1, 4] R: ( 5, -5]

Step-by-step explanation:

The domain is the point most to the left, and the point most to the right on the graph. The range is the point highest up and the point lowest down on the graph. You make a parentheses when the circle is hollow, but use a bracket when the circle is filled.
