6.2 hours
Every time Chelsea babysits she earns 2 + 5x
We want at that to amount to at least 33. *_> is great than or equal to*
33 _> 2+5x
Subtract 2 from both sides
31_>5x
Divide by 5 from both sides
6.2_>x
So Chelsea must work for at least 6.2 hours. She could work more but at least 6.2

What is the solution to the system of equations graphed below y=1/2x+2 y=-2x+-3

vladimir1956 [14]

Answer:

Step-by-step explanation:

given the system of equations y=1/2x+2 and y=-2x+-3, since the 2 equations are functions of y, we will equate both equations together and calculate the value of x as shown

1/2x+2 = -2x-3

x/2+2x = -3-2

5x/2 = -5

5x = -10

x = -10/5

x = -2

Substituting x = -2 into any of the equation to get the value of y we have;

y = -2(-2)-3

y = 4-3

y = 1

The solution to the system of equation (x, y) = (-2, 1)
