Answer:
The vertex form is: y = 3(x-2)^2 + 7
. The vertex is (2, 7)
Step-by-step explanation:
Write the function: y = 3x^2 - 12x + 11 in vertex form
The vertex form of a quadratic equation is:
y = m(x - a)^2 + b where (a,b) is the vertex
For y = 3x^2 - 12x + 11
Solve for m
y = 3(x^2 - 4x) + 11
Complete the Square:
y = 3(x^2 - 4x + 4) + 11 - 4
y = 3(x - 2)^2 + 7
The vertex then is (2, 7)
13x-8y=12
Use the slope intercept form to solve the problem.
y = mx+b when the slope is m and the y-intercept is b.
Slope: 13/8
Y-intercept: -3/2

<u>Step-by-step explanation:</u>
Coterminal means it is in the same place on the Unit Circle but one or more rotations clockwise or counterclockwise.
Note: one rotation is 2π (which is equivalent to )
We have two classrooms and seven packages.
This means we need to divide the seven packages in half (two pieces).
7packages ÷ 2 classrooms = 7/2 = 3.5 packages per class
(three and a half packages)
