Step-by-step explanation:
1. f+15<6
 = f<6-15
 f < -9
2. f+12 >16
 f >16-12
 f > 4
 
        
             
        
        
        
A difference of 840 degrees
800 - (-40) = 840
When removing a negative number from a positive number you get a positive
- + - = +
800 - (-40)

Answer:
6 
Step-by-step explanation:
Multiply all three sides by 8 to get x by itself 
16/3 < x < 7
5 1/3 < x < 7
so it’s between 5 and 1/3 and 7. the only answer between those two would be 6. 3 and 4 is too less. 5 is also too less. 
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
nth term = (n-1)th term + common difference
d = -10
a₁ = 3
a₂ = a₁ + d = 3 + (-10) = -7
a₃ = a₂ + d = -7 + (-10) = -17
a₄ = a₃ + d = -17 + (-10) = -27
a₅ =a₄ + d = -27 + (-10) = -37
a₆ = a₅ + d = -37 + (-10) = -47
First six terms: 3 , -7 , -17, -27, -37 , -47
 
        
             
        
        
        
Solución 1: 2(x) + 3(y) = 80 
solución 2: 3(x) + 2(y) = 70
3(y) + 2(x) = 80
2(y) + 3(x) = 70 
2y = -3x + 70 
y = -3x÷2 + 35
2x + 3(-3x÷ 2+35) = 80   
 -5x÷2 = -25   
-5x = -50
5x = 50    
 x-intercept: 10  
 x = 10  
 y = -3x÷ 2+35
  y = -(3÷2)(10)+35 = 20  
x-interpcet: 10 
y-intercept: 20
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
solución: x - 8y = 0
solución x + 4y = 480
-8y + x = 0
4y + x = 480
x-intercept (solución 2)
x = -4x + 480
x-intercept (solución 1) 
4y + 180 - 8y = 0
 -12y = 480
y-intercept: 40
x-intercept: 320
