11. 2x+3x+1=21
5x+1 =21
5x=20
x=4
TU= 2(4) which is 8
UB= 3(4)+1 which is 13

12. 4x-1 +2x-1=5x
6x-2=5x
-2=-1x
2=x

X=2
TU= 7
UB= 3
TB=10

Problem 13:

2x-8=x+17
2x=x+25
x=25
AB =42
BC=42
AC=84

Problem 14:
3x-31
-x+6
=
2x-37 for BC part now we solve for x
x+6=2x-37
6=x-37
43=x
So :
X=43
AB=49
AC=98
BC=49

Explain how you could determine the vertex of the given quadratic function graphically. f(x) = (x + 2) (x -4)

bearhunter [10]

Answer:Get the equation in the form y = ax2 + bx + c.

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

To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y.

The graph below plots a function f(x):

Karolina [17]

By definition we have that the average rate of change of the function is given by:
$AVR = \frac{f(x2) - f(x1)}{x2 - x1}
$
Substituting values we have:
$AVR = \frac{100 - 50}{2 - 0}$
Rewriting we have:
$AVR = \frac{50}{2}$
$AVR = 25$
Answer:
If x represents time, the average rate of change of the function f(x) in the first two seconds is 25.
