Answer:
B. -3
Step-by-step explanation:
To find the distance between two points, we can use the distance formula:
√(12 - 0)^2 + (3 - 5)^2
√148 = 12.2
For this case we first define varials:
x: number of hours working as cashier
y: number of hours working as a baby sit
We now write the system of equations:
6x + 6y ≥ 60
x + y ≤ 12
Answer:
to solve the real-world problem the system of inequalities is:
6x + 6y ≥ 60
x + y ≤ 12
4x + 5y = 5 / (-1)
8x + 5y = 25
-4x - 5y = -5
8x + 5y = 25
-4x + 8x = -5 + 25
4x = 20
x = 5
4x + 5y = 5
4*5 + 5y = 5
20 + 5y = 5
5y = 5 - 20
5y = -15
y = -3
8x + 5y = 25
8 *5 + 5y = 25
40 + 5y = 25
5y = 25 - 40
5y = -15
y = -3
