The axis of symmetry for the graph of the function f(x)=3x^2+bx+4 is x= 3/2. what is the value of b

b = -9

Step-by-step explanation:

The function is given as :

The axis of symmetry for this function is x = 3/2

It is required to find the value of b. The axis of symmetry of a parabola is a vertical line that intercepts its vertex at its horizontal coordinate. It can be given by :

Putting x = 3/2 and a = 3 we get :

So, the value of b is -9.

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

where are the choices?
