Find the maximum value of y = -2(x - 4)2 - 6. A) -6 B) -4 C) -2 D) 4
otez555 [7]

Y=-2(x-4)^2-6

The -6 makes it shift from origin(0,0) to (0,-6)

Then the -4 inside with x, makes it shift to the right by for, so the center would be now instead of (0,0), (4,-6).

As it has a negative A factor, it is a parabola open downwards, so the center is the maximum value.

Answer: (4,-6)

Hope you get it!

Jill made chocolate shakes for a party she used 1/4 cup of milk for each shake how many ounces of milk did Jill need to make for
PIT_PIT [208]
Since we know that Jill needs 1/4 of a cup of milk per shake and that she wants to make 36 shakes, you would set up an expression that involves multiplying 1/4 and 36 together: 1/4*36
Then, when you multiply, you get 36/4 which simplifies to 9.
Your answer would be 9 ounces
