What is the minimum point of the equation x^2+19=9x

Mathematics
1 answer:
azamat3 years ago
3 0

Answer:

The minimum point is (4.5, -1.25).

Step-by-step explanation:

x^2+19=9x

= x^2 - 9x + 19 = 0

Convert to Vertex form:

(x - 4.5)^2 - 4.5^2 + 19 = 0

= (x - 4.5)^2 - 1.25.

The minimum point is (4.5, -1.25).

A angles of an equilateral triangle are congruent. If x represents the measure of the third angle of the triangle, what is x?
Tatiana [17]

Answer:

D

Step-by-step explanation:

Since x is the measure of the third angle and all 3 angles are congruent then

All 3 angles have a measure of x

The sum of the 3 angles in a triangle = 180°, this

x + x + x = 180 ← is the required equation

3x = 180 ( divide both sides by 3 )

x = 60

deff fn [24]

Considering the angle of the ray, it is found that the value of x is of x = 55º.

<h3>What is the angle of the ray?</h3>

The ray has an angle of 180º. It is composed by:

  • Angle x.
  • An angle of 35º.
  • An angle of 90º.

Hence:

x + 35 + 90 = 180

x = 180 - 125

x = 55º.
