Answer:
<em>- 112 + 100 n</em>
Step-by-step explanation:
= 
+ (n - 1 )d
~~~~~~~
= - 12
d = 100
= - 12 + 100( n - 1 )
= - 12 + 100n - 100
<em>= - 112 + 100 n</em>
Answer:
f-1(x)=x-1/2
Step-by-step explanation:
Switch x and y and solve for y
x=y+1/2
y=x-1/2
Answer:
Function
Step-by-step explanation:
Two different X's could equal the same Y value so this is a function. Remember if there's multiple of the same input (x) equalling different outputs (y) then it is not a function. If there's multiple inputs (x) equalling the same output (y) it's just coincidence and works.
You times it by one and then add the two zeros so your answer is 3,500
