The answers to your question are C, D, and E
If there are repeats in the X column, then it's not a function. If there are no repeats, then it is! If there are repeats in the Y column, that's ok, but there cannot be repeats in the X column.
Hope this helps! If you need any other help, just tell me!
 
        
             
        
        
        
Answer::.x=6,y=2
3x - 5y = 8......(1)
X - 5y = - 4......(2)
subtracting equation 2 from 1 we get 
Step-by-step explanation:
3x - 5y = 8
X - 5y = - 4
-
------------------
2x=12
x=12/2=6
multiplying equation 2 by3 weget
3x-15y=-12........(3)
subtracting equation 1from 3
3x-15y=-12
3x-5y=8
-
------------------
-10y=-12-8
y=-20/-10=2
 
        
             
        
        
        
Answer:
)x + 5)(x - 5)
Step-by-step explanation:
x² - 25 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b), thus
x² - 25 = x² - 5² = (x + 5)(x - 5)
 
        
             
        
        
        
Answer:
The inequality to represent the situation is  and the team must sell at least
 and the team must sell at least  "Jaguar Cards".
 "Jaguar Cards".
Step-by-step explanation:
Given: The ADMHS football team is trying to raise money to buy new equipment so the players are selling "Jaguar Cards" for  each.
 each.
If the football team needs to raise at least  for equipment.
 for equipment.
To find: The inequality to represent the situation and the least number of "Jaguar Cards" the team must sell.
Solution:
Let the ADMHS football team sold  "Jaguar Cards" for
 "Jaguar Cards" for  each.
 each.
Now, the football team needs to raise at least  for equipment.
 for equipment.
So, the inequality to represent the situation is  .
.
Now, on solving we get,

 
 

Hence, the inequality to represent the situation is  and the team must sell at least
 and the team must sell at least  "Jaguar Cards".
 "Jaguar Cards".
 
        
             
        
        
        
Step-by-step explanation:
∠4 = ∠1 & ∠2 = ∠3
360 - 2(98) = ∠2 + ∠3
∠3 = 164/2
∠3 = 82°
