Given that the quadratic equation 3x^2+bx-2 has x-intercept {-2, 4}. What is the "b" value.
Luba_88 [7]

The value of b is b=3

Explanation:

The given quadratic equation is y=3x^{2} +bx-2

And has x - intercept (-2,4)

To determine the value of b, let us substitute the coordinates (-2,4) in the given quadratic equation y=3x^{2} +bx-2

Substituting the x - intercept in the equation y=3x^{2} +bx-2, we have,

4=3(-2)^{2} +b(-2)-2

Simplifying, we have,

4=3(4)-2b-2

4=12-2b-2

Adding the constant terms, we get,

4=10-2b

Subtracting both sides by 10, we have,

-6=-2b

Dividing both sides by -2, we get,

b=3

Hence, the value of b is b=3

Kipish [7]

Answer:

After 15 years the use of said machine is no longer profitable

Step-by-step explanation:

it should be used, as long as the money generated is not smaller as the costs generated. By setting both formulas equal (calculating the x value for when they are equal) you get x = 15 and x = -2.5(which doesnt make sense in this context).
