Answer:
One solution
Step-by-step explanation:
They have isolated y for you in both equations so you can plug either one into the other.
y = 3x - 1
2x + 7 = 3x - 1
isolate the x
7 = x - 1
x = 8
Go back to the original and plug 8 into x to get y.
y = 2 (8) + 7
y = 16 + 7
y = 23
This means at (8, 23) y = 2x+7 is equal to y = 3x-1. In other words they share a point at (8, 23). This is the only solution because for any other x and y they'd not be equal.
Answer:
59.58333
Step-by-step explanation:
715/12
write in long division format ( which u did )
divide 71 by 12 to get 5
multiply 71 by 12 = 5
subtract 60 by 71
bring down the next number
115/12 =9
multiply 12 by 9
subtract 180 by 115
add a decimal on the top and bring down zero
divide 70 by 12 = 5
multiply 5 by 12
subtract 60 - 70
bring down a zero
divide 100 by 12 = 8
multiply 12 by 8
subtract 96 by 100
bring down zero
divide 40 by 12 = 3
anddd u get the point
sorry it took so long
