X = 1 hr lessons and y = 1/2 hr lessons

x + y = 35......y = 35 - x
40x + 25y = 1115

40x + 25(35 - x) = 1115
40x + 875 - 25x = 1115
40x - 25x = 1115 - 875
15x = 240
x = 240/15
x = 16 <=== there are 16 one-hr lessons
and 19 half-hr lessons

The values in the table represent a function.
Hatshy [7]

Given:

The values in the table represent a function.

x          f(x)

-2          1

1            3

4          -2          

-3          0

0           4

To find:

Function notation for the ordered pair given in the first row in the table.

Solution:

We know that, if a point (a,b) is on the function, then f(a)=b.

From the given table, the ordered pair given in the first row is (-2,1). So,

f(-2)=1

Therefore, f(x)=1 when x is -2.
