Step-by-step explanation:
3/8 and 11/15
LCM = 30
3/8x4 and 11/15x2
12/30 and 22/30
22/30-12/30
=10/30
The difference is 10/30
The larger sum is 11/15

Answer:
C. f(x) = 40(1/4)^x
Step-by-step explanation:
Check all the options:
When x = 0
A. f(x) = 1/4(40)^x
f(x) = 1/4(40)^0
f(x) = 1/4(1)
f(x) = 1/4
When x = 0
B. f(x) = 1/2(40)^x
= 1/2(40)^0
= 1/2(1)
f(x) = 1/2
When x = 0
C. f(x) = 40(1/4)^x
= 40(1/4)^0
= 40(1)
= 40
When x = 0
D. f(x) = 4(1/3)^x
= 4(1/3)^0
= 4(1)
= 4

State if the product of rational numbers and integer is an integer
The statement is false and the proof is as follows
Literally, rational numbers are decimal numbers that can be represented as a fraction of two integers;
Take for instance: 0.2, 0.5, 2.25, etc.
When any of these numbers is multiplied by an integer, the resulting number can take any of two forms;
1. It can result to an integer:
<em>For instance;</em>



2. It can result in a decimal number
<em>For instance;</em>



From (1) above, we understand that the product can result in an integer.
Hence, the statement is false

Multiply both sides of the inequality by 2
x-10>-14
move constant to the right side and change its sign
x>-14+10
calculate the sum
x>-4
answer is x>-4
