1.

Find the domain of the function.

8

G(x)= _____

4 - 3X

x can not have values such that 4-3x = 0 è x = 4/3

Choose the correct domain below.

(a) {x | x does no equal 43}

(b) {x | x does not equal 8}

(c) {x | x does not equal 0}

(d) {x | x >_ 4/3} (>_) means grater than or equal to

3. 80% of what number is 20?

0.80 x = 20 è x = 20/0.8 = 25

The answer is 25

4. One of three consecutive passes, a football team gains 9 yards, loses 27 yards, and gains 49 yards.
