X + y = 33
x - y = 9 Add the 2 equations together
---------------
2x = 42 Divide both sides by 2
x = 21
Use the original equation and plug 21 in for x, then solve.
x + y = 33
21 + y = 33
Subtract 21 from both sides
y = 12
One list had 21 items on it and the other list had 12 items on it.
Answer:
B - -5 < y < 5
Step-by-step explanation:
Range is highest and lowest y value the graph goes to.
You can see on the graph that it does not pass 5 and -5
Answer:
-2
Step-by-step explanation:
You can use the equation x+(x+1)=73 in this situation.
This would equal to 2x+1=73, which makes 2x=72. X would be 36, and 36+37 is 73.
Basically your answer would be any two integers, starting from 37 and up.
Ex. 37+38=75 or 38+39=77, and so on.
Only positive numbers can apply to this question because any number consecutive to a negative number would *definitely* be less than 73.
