This graph is a parabola. Therefore, the point of symmetry occurs at the x where f'(x)=0. From this we can find the axis of symmetry:

f(x)=-5x^2-20x-10\\f'(x)=-10x-20=0\\-10(x+2)=0\\x+2=0\\x=-2

The axis of symmetry is x = 2.

Answer:

when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°.

Step-by-step Explanation:

The relationship between an intercepted arc and an inscribed angle is given as:

the measure of the intercepted arc = twice the inscribed angle that intercepts it.

Also, by virtue of this, when two inscribed angles intercepts the same arc, both inscribed angles are said to be congruent. And the measure of both angles equal the measure of the arc they both intercept.

Therefore, if the measure of an arc, that is intercepted by 2 inscribed angles, is given as 75°, both inscribed angles equal 75° as well. Thus, each of the inscribed angles is half the measure of the intercepted arc.

Therefore, the statement that is true about inscribed angles is: "when two inscribed angles in one circle both equal 75°, the two angles must intercept the same arc that measures 75°."

Use the substitution method to solve the system of equations. Choose the correct ordered pair.
zubka84 [21]

Answer:

A) (3,14)

Step-by-step explanation:

6x - 4 =7x - 7

subtract 6x from both sides

-4 = x -7

add 7 to both sides

3= x

now that we know the value of x, plug it into either equation to get y=14
