hi
i think this will help you
the graph will shift 3 units to the right
Step-by-step explanation:
ED = EB
2x +3 = 5x -15
3+15=5x -2x
18 = 3x
18 ÷ 3 = x
x = 6
Answer:
an expression for the # of bottles enrique collected in all would be 2b+7
Step-by-step explanation:
This is a linear equation y = mx+b, where m is the slope and b, the y-intercept.
Since we know this graph passes through A(1,4) and B(5,6), we can find easily the equation:
1st- Calculate m = (y₂-y₁)/(x₂-x₁) → m = (6-4)/5-1) = 2/4 →m =1/2
Now y = (1/2) + b.
2nd. To calculate b, replace x and y by either the coordinate of A(1,4) or B(5,6)
Let's take A where x = 1 and y = 4 for instance:
y =(1/2)x + b
4=(1/2)(1) + b
4=1/2 + b
4-1/2 = b and b= 7/2
Finally te equation becomes: y = (1/2)x + 7/2
