F(x)= (x - 6)(x + 2)? What is the vertex of the quadratic function

Mathematics
1 answer:
Mars2501 [29]3 years ago
6 0

Answer:

With this form, we can tell that the x intercepts are x=6 and x=-2. So the x coordinate of the vertex is 2

Step-by-step explanation:

Two parallel lines are crossed by a transversal.
nadya68 [22]

Answer:

Option B) y = 50

Step-by-step explanation:

We are given the following information:

Two parallel lines are crossed by a transversal.

The attached image shows the intersection of transversal and the angles.

As clear from the image, the given pair of angles form alternate interior angles.

If two parallel lines are cut by a transversal, then the pairs of alternate interior angles are congruent or equal

Thus, y = 50 degree

A cab company offers a special discount on fare to senior citizens. The following expression models the average amount a cab dri
steposvetlana [31]

Answer:

  D. The constant 250 represents the average collection when no seniors ride.

Step-by-step explanation:

A -- the entire expression represents the driver's pay, not just the constant 250.

B -- collections continue to increase as x goes up, so 250 is the minimum, not the maximum.

C -- x is the number of seniors; 250 is in units of collections (dollars?), not numbers of seniors.

D -- indeed, 250 is the "y-intercept" of the expression, hence the collection when no seniors ride.

What is the measure of each exterior angle of a decagon?
NemiM [27]
The sum of all of the exterior angles of any regular polygon is 360  (I'm assuming by decagon you mean a regular dodecagon).

Because the total has to be 360, and a decagon has 10 sides, you divide 360 by 10 to get each exterior angle.

360 ÷ 10 = 36, so each exterior angle of a decagon is 36 degrees.

Evaluate piecewise functions
Mama L [17]

6 is neither equal to 0 nor equal to 7, so the last "piece" of h(x) applies. Then

h(6) = 3•6 - 2 = 18 - 2 = 16
