Answer:
Step-by-step explanation:
The point of intersection is also the solution to this system of equations.
We can solve this system using substitution:
Add 3 to both sides:
Divide both sides by 3
Then, substitute 6 for x to solve for y:
Therefore the point of intersection is:
Collect like terms.. 7b-9=30 . Add 9 to both sides to isolate b. 7b= 39. Divide both sides by 7. B=39/7 maybe there was a problem is this equation maybe it was 7b+9=30 instead of 7b-9 =30
1/2 is the probability the coin would land heads up both times.
