Answer:
1.5 billion
Step-by-step explanation:
Turn both mixed fractions into improper fractions
2 3/5 = 13/5
1 4/7 = 11/7
now multiply the improper fractions
13/5 x 11/7
143/35 or 4 3/35
The domain of a(x) is all of R. The domain of b is the range where

. We can calculate the composition boa by changing in the expression for b, every x with a(x). Hence, boa(x)=

=

. Again for a function with a root to be defined, we need that the expression under the square root has to be positive. Hence, 3x-3

0.Thus, the set where this holds is

. This is also the domain of the function boa(x).
Answer:
x is less than or equal to 29
Step-by-step explanation:
-49 <_ 9 - 2x
isolate the variable.
-49 - 9 <_ 9 - 2x - 9
-58 <_-2x
-58/-2 <_-2x/-2
When dividing or multiplying by negatives, flip the sign.
-58/-2 <_-2x/-2
29 >_ x
x <_ 29
x is less than or equal to 29
