True or false?
ok, so just use your head and use this simple memory tool
for remembering inequalities, the aligator eats the bigger number
x>y means x is biger than y
x<y means x is smaller than y or y is bigger than x
remember: the farther to the right a number is, the bigger it is
8<9
and
-10<-3 since -3 is farther to right than -10
so see them
b. 5>7, duh, false
c. 15≥17, are you kidding me, false
d. true
e. nay, no negative number is ever greater than a positive, false
f. true, -2 is farther to the right than -13 is
g. x>4, x is any number bigger than 4, not including 4
h. x is any number bigger than 8, not including 8
i. x is less than or equal to -4, so it can be -5, or even -4
Answer:
B. f -1(x) = x + 2 / 5
Step-by-step explanation:
To find the inverse of a function we need to interchange x and y an solve for y.
Since 
, then
Add 2 to both sides
Divide both sides by 5
We can conclude that the correct answer is B. f -1(x) = x + 2 / 5
Answer:
x=-1
Step-by-step explanation:
2x -2= -4
2x = -2
x = -1
