The axis of symmetry for the graph of the function f(x)=3x2+bx+4 is x = 3. What is the value of b?

Kobotan [32]

Answer:

A)-18

Step-by-step explanation:

Given a quadratic equation of the form $y=ax^2+bx+c$ , the axis of symmetry is determined by the formula $x=-\frac{b}{2a}$ .

If the axis of symmetry of the equation: $f(x)=3x^2+bx+4$ is 3, then:

a=3, b=?, x=3

$x=-\frac{b}{2a}\\3=-\frac{b}{2*3}\\b=-6X3=-18$

The correct option is A.

What are the measurements of the two angles in the sketch?

Setler79 [48]

Answer:

Step-by-step explanation:

So you got (4x-15) and x

We know it will equal 180 total so you will do

(4x-15)+x=180

Add 15 to each side

4x+x=195

5x=195

Divide each side by 5

x=39

So if X equals 39, your only possible answer is A
