3x+0.5(10x-6)=21
3x+5x-3=21
8x-3=21
8x=24
x=3
that's the whole thing.
Answer:
70% actually it depends on if you use a pattern or you flip the coin in all three trys! but yeah that's it i believe
Answer:
Line: , Graph: desmos(.com)/calculator/tiptlly8xj
Step-by-step explanation:
First off, your slope is wrong. I will show you how to find the correct slope, and will make the graph.
The change in is .
The change in is .
That makes the slope .
Recall point-slope form. That is, given a point and a slope , the line through the given point with the given slope is of the form .
Plugging in one of the points, (6, 8)(we could also use (12, 16)) to the point-slope equation gives the line: .
Converting to slope-intercept form()...
Simplifying the right hand side gives .
Adding to both sides gives the desired line, .
The graph is shown on Desmos in the answer.
All you have to do is stack up the numbers and subtract to find the answer
