Answer:
a=3, c=-4, x=8
Step-by-step explanation:
 5=4a-7
4a-7=5
 4a=5+7
 =12
 a=12÷4
 =3
3-8c=35
 -8c=35-3
 =32
 c=-32÷8
 =-4
-1/2x-7=-11
 -1/2x=-11+7
 =-4
 x=4÷1/2
 =4/1×2/1
 =8
 
        
             
        
        
        
estimate value of :- 2.99548 is 3
estimate value of :- 1.8342 is 2
So 3•2=6
so 6 is your answer 
 
        
                    
             
        
        
        
Answer:
Step-by-step explanation:
m has a slope of -2 and a y intercept of 4
y = -2x + 4
n has a slope of 1 and a y intercept of -1
y = 1x - 1
y = x - 1
Ah!... the invisible questions in a sideways posted image.
t has a slope of zero and a y intercept of 3
y = 0x + 3
y = 3
p has infinite slope and no y intercept.
x = -5
