Answer:
x=2 
Step-by-step explanation:
8 + x = 4x +2 
Subtract 4x from both sides:
8 + x - 4x = 4x + 2 - 4x 
Group like terms: 
x - 4x + 8 = 4x + 2 -4x 
Simplify the arithmetic:
-3x + 8 = 4x + 2 -4x 
Group like terms:
-3 + 8 = 4x - 4x + 2 
Simplify the arithmetic:
-3x + 8 = 2
 
        
             
        
        
        
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0)
You need to find "m" and "b".
If you look at the graph, when x = 0, y is 1, so the y-intercept is 1.
y = mx + 1
To find "m", you can use the slope formula and find two points on the graph and plug it in, or you can use this:

Rise is the number of units you go up(+) or down(-)
Run is the number of units you go to the right.
If you look at the graph, from each point you go up 1 unit, and to the right 1 unit. So your slope is  or 1
 or 1
y = 1x + 1
y = x + 1
 
        
                    
             
        
        
        
(-6)(-0.4)(-0.5) = (-1)6⋅4⋅5⋅10⁻² = -1.2
        
             
        
        
        
Answer:
Cost of tshirt = £7.29
Cost of what = £0.86
Step-by-step explanation:
2t +3h = 12; 10t + 15h = 60
5t + 4h =33; 10t + 8h = 66
15h -8h = -6
7h = -6; h = -6/7; h = 0.86
2t +3(-6/7) =12
14t -18 = 84
14t = 102; t = 102/ 14; t=7.29
