The points (0, -3) and (5, -2) are solutions to the system of equations.
To find the solutions, you first have to graph both of the lines in the problem.
y = -2x - 3 and y = 2x + 1. Then, to shift them to an inequality, you have to shade the half-plane that they represent.
The solution is the space that they have in common. In this case, it will be on the right side of the graph.
The points (0, -3) and (5, -2) are included in the shaded region they have in common.
Convert hour to minutes:
2/3 hours = 2/3 x 60 = 40 mins
30 mins 10 mins

Answer: 8:10
Answer:
Ax+By=C
Step-by-step explanation:
basically the standard form of any linear equation, y=mx+b. y is the y coordinate, m is the slope, x is the x coordinate, and b is the y-intercept (where x is 0 on the line).
I think your answer would be D.0562
<span>The given function is f(x) = (7x + 1)/2. Write it as y = (7x)/2 + 1/2. To determine the inverse do these 3 steps. Step 1: Swap x and y to obtain x = (7y)/2 + 1/2. Step2: Solve for y. First, multiply through by 2 to obtain 2x = 7y + 1. Second, subtract 1 from each side to ontain 2x - 1 = 7y. Third, divide through by 7 to obtain (2x - 1)/7 = y. Step 3: Set y to the inverse of f(x) to obtain f^(-1) (x) = (2x - 1)/7.</span>
