Answer:

The answer to your question is  Equations 1, 2 and 5 are equivalent

Step-by-step explanation:

1.- Equation 1

    2 + x = 5              x = 5 - 2         x = 3

2.- Equation 2

    x + 1 = 4               x = 4 - 1         x = 3

3.- Equation 3

    9 + x = 6             x = 6 - 9         x = -3

4.- Equation 4

   x + (-4) = 7           x - 4 = 7          x = 7 + 4             x = 11

5.- Equation 5

   -5 + x = -2            x = 5 - 2         x = 3

Below is the graph of y=b^x. Find b.
omeli [17]
Y = <span>b^x

when x = 1
y = b^1
y  = b

Therefore, the value of b is the same as the value of y when x =1
From the graph,
When x = 1, y = 0.5
Therefore, b = 0.5


To confirm this

From the graph,

When x = -1, y = 2
Since </span>y = b^x<span>
2 = </span>b^-1
2 = 1/b
2b = 1
b = 0.5

When x = -2, y = 4
Since y = b^x
4 = b^-2
4 = 1/(b^2)
b^2 = 1/4
b = √(1/4)
b = 1/2
b = 0.5

Therefore, it is conformed that b = 0.5
