The lines intersect at two places.
They intersect at approximately (-2,8) and (2,3)
Looking at the choices they would be at (1.8,3.2) and (-2.8,7.8)
The answer is D. Both A and B.
Hi there!
The way that an infinite number of solutions is achieved is when the two equations, when solved together, get an answer which is just a number equal to the same number. To do this, first substitute 6x-b in for y in the second equation.
Now, we see that b needs to be equal to -3 when multiplied by -1/2. When both sides are divided by -1/2, b becomes equal to 6. Thus, b must be 6.
Check work:
Thus, as they are equal to each other, the answer is correct. b = 6.
Hope this helps!
Answer: y=5.25x+12.50
Step-by-step explanation:
The original 12.50 is how much she pays each month regardless of rented movies, it is the 0 value and doesn't change. Each rented movie costs 5.25 (17.75-12.50=5.25) and that value would be multiplied by the amount of movies she rents that month, and then added onto the original base value.
Combine like terms you would get 4c=48 then divide it by 4 you'll get c=12
Answer:
12 to 8, 6 to 4
