Conceptually, you are asking for the additive inverse of 8. By definition, in fact, the additive inverse of a number 
is a number 
such that 
You obtain the additive inverse of a number by switching its sign, so the additive inverse of 8 is -8. In fact, you have
''Decreased'' means subtract and ''times'' means multiplication so the algebraic expression should be 15 - 2 * p.
Answer:
thxfor free points
Step-by-step explanation:
Pick two points
(2, 18) and (4,21)
(21-18)/(4-2) = 3/2
The slope is 3/2
The denominator is the bottom portion of the fraction. Example 4/6, the 6 is the denominator. The easiest way to start out in finding the common denominator is to see what number, 8 and 14, go into equally. Example: 1/4 and 1/3, 3 and 4 both go into 12. If you multiply 4 by 3 as well as 3 by 4 you get 12 both times. Now try it with 8 and 14.
What number can 8 and 14 go into equally? (56)
8x7=56...14x4=56
