9. What is the vertex of the function? f(x) = 3x² - 8x + 10​
Delvig [45]

Answer:

The vertex of the function is (1.333, 4.667)

Step-by-step explanation:

1. Calculate -b / 2a. This is the x-coordinate of the vertex.

2. simply plug -b / 2a into the equation for x and solve for y.

Y = 3x^{2}  - 8x + 10\\Compare with the form of   y = ax^{2} + bx + c\\So that means a = 3, b = -8, and c = 10.

Calculate -b/2a:

X = -(-8)/2(3)

X = 8/6

This is equal to 1.33 recurring

Plug 8/6 for x and solve for y:

Y = 3x^{2} - 8x + 10

Y = 3(\frac{8}{6})^{2} - 8(\frac{8}{6}) + 10

Y = \frac{48}{9} - \frac{64}{6} + 10\\

This is equal to 4.66 reccuring.

Given that y varies directly with x in the table below, what is the value of y if the value of x is 7?
Black_prince [1.1K]
Write out the governing equation:

y = kx.

Take any point from the given table.  You haven't shared the table, so I will invent a point:  (2, 9).

Then find k:  k = 9/2        Then the equation becomes   y = (9/2)x.

Now let x = 7 and find y:                           y = (9/2)(7) = 63/2     

Answer:         y = 63/2
