The equation f(x) = 5x2 − 30x + 6 represents a parabola. what is the vertex of the parabola?

(−5, 281)
(5, −19)
(−3, 141)
(3, −39)

D.

Step-by-step explanation:

We have been given an equation . We are asked to find the vertex of parabola for our given equation.

We will use formula to find the x-coordinate of the vertex of parabola, then we will substitute the value of x-coordinate in our equation to find the y-coordinate of the parabola.

Therefore, the x-coordinate of the vertex of the parabola is 3.

Now let us substitute in our given equation to find the y-coordinate of the parabola.

So, the y-coordinate of the vertex of parabola is . The point represents the vertex of the parabola represented by our given equation and option D is the correct choice.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.

happy to

pls mark as brainliest.

step-by-step explanation:

because where the point where the 2 lines intersect is (3,-1) the x value is 3
