Answer:
Step-by-step explanation:
So when we solve the inequality:
2(x - 2) >_ 2
x - 2 >_ 1 (divided 2 from both sides)
x >_ 3 (added 2 to both sides)
So with our final equation, we can work out that the answer is b, but d is also correct so I'm assuming that the inequality needs to be represented on a number line as hey usually are.
Hope this helps,

Answer:
(9/8)^-1 = 8/9
Step-by-step explanation:
To re write without an exponent means we will eliminate it's power.
This fraction came with the power of -1.
And when the power of a fraction or a whole number comes with power of -1 what it simply means it's the inverse of the number.
So let's evaluate the above fraction.
(9/8)^-1 = 1/(9/8)
(9/8)^-1 = 1*(8/9)
(9/8)^-1 = 8/9
Answer:
Student ticket: $12, Adult ticket: $14
Equations: 260=10x+10y, 94=2x+5y
Step-by-step explanation:
Set adult tickets as y
Set student tickets as x
First day: Total made is 260 so set that equal to 10x + 10y
--> 260=10x+10y
Second day: Total made is 94 so set that equal to 2x + 5y
--> 94=2x+5y
I find it easier to have simplified terms so simplify (divide by 2) the first equation to get: 130=5x+5y
All you have to do now is solve for the two variables.
94=2x+5y - (130=5x+5y) --> x=12, y=14
