Answer:

The equation is 0.11x + 0.25 = 0.15x (I think) and the answer is 6.25 = x

-0.11x              -0.11x

0.25 = 0.04x Divide both sides by 0.04

6.25 = x

Which graph represents a function with an initial value of 1/2
melisa1 [442]
<span>The initial value is the value of the y-coordinate when the x-coordinate is equal to 0. That is the same to say the value at which the graph intercepts the y-axis. So, you justt have to pick the graph whose line intercepts the y-axis at 1/2. </span>
