Answer: x = - 3

Step-by-step explanation:

The equation is in a standard form of equation as;

y = ax^2 + bx + c, and therefore, the axis of symmetry is given by the formula,

X = - b / 2a.

Therefore using that in the question, a = 1 and b= 6

Therefore, the axis of symmetry is:

x = - (6) / 2(1) which gives

x = - 3

Answer:

m∠3 = 24°

Step-by-step explanation:

By the theorem,

"Intercepted arc measures the double of the inscribed angle formed by two chords meeting at one point of the circle."

In the given picture,

∠3 is the inscribed angle subtended by the arc ED and is the intercepted arc.

Therefore, m∠3 = $\frac{1}{2}m(\text{arc}ED)$

m∠3 = $\frac{1}{2}(48)$

= 24°

Measure of angle 3 is 24 degrees.

9. Consider the function f(x) = x² + 3x – 4.

BaLLatris [955]

Answer:

c. f(x) = (x + 4)(x - 1)

Step-by-step explanation:

Since you're familiar with the product of two binomials:

(x +a)(x +b) = x² + (a+b)x + ab

you know that the constants in the binomial factors must ...

have a product of -4
have a sum of +3

All of the choices except B have binomial constants that have a product of -4.

In order, the sums of the remaining choices are ...

A: 1-4 = -3

C: 4-1 = 3 . . . . this is the correct choice

D: -2+2 = 0
