Well, the formula for area of a triangle is base times height/2
= 13 * 12
= 156
156/2 = 78

So, the area of this triangle is 78cm^2.

PLEASE HELP ASAP!!!!!!!!!!!!!!!!!
Kamila [148]

Answer:

Twelve tickets cost $30 --> True

Thirty tickets cost $12 --> False

Each additional costs $2.50 --> True

The table is a partial rep --> True

ordered pairs --> False

Step-by-step explanation:

Twelve tickets cost $30 --> True, you can literally see that in the table

Thirty tickets cost $12 --> False, 30 is not in the table so you don't have that information. Besides, $12 is an unlikely low value for so many tickets.

Each additional costs $2.50 --> True, you can see the difference in the TotalCost column to be consistently 2.50.

The table is a partial rep --> True, values below 11 are not shown for example.

ordered pairs --> False --> Then the x value should be first, e.g., (11, 27.50), since the cost y is a function of the number x.

What is the graph of the function f(x) = -x^2+x+20/x+4
mr_godi [17]
F(x) = (-x²+x+20) / (x+4)

-x²+x+20     | x+4
+x²+4x          -x+5
 \\\\ 5x+20
     -5x-20
      \\\\\\\\\
 
 f(x) = (x+4)(-x+5) / (x+4)
 
 f(x) = (-x+5)

The graph is a decreasing line, with origin from 5.
