Answer:
(a) (3.5, 1.6)
Step-by-step explanation:
The solution of the system of equations is the point where the lines cross. That point appears to be slightly above the middle of the grid square bounded horizontally by x=3 and x=4, and bounded vertically by y=1 and y=2.
__
The solution ordered pair is (x-coordinate, y-coordinate). We observe that the x-coordinate is approximately 3.5, The y-coordinate is slightly more than 1.5, but not as great as 1.9. So, the approximate solution is ...
(x, y) ≈ (3.5, 1.6)
_____
The graphing calculator shows the solution is quite close to (3.5, 1.6).
Answer:
x = 7
Step-by-step explanation:
=> 7x+9 = 8x+2 (Corresponding angles are equal)
=> 8x-7x+2 = 9 (Subtracting 7x to both sides)
=> x = 9-2 (Subtracting 2 to both sides)
=> x = 7

Step-by-step explanation:
Answer:
Step-by-step explanation:
<em><u>Find the Rate of Change</u></em>
The rate of change = Δy/Δx
(20 - 16) / (8 - 6) = 4/2 = 2 gal / minutes
<em><u>Slope and Graph</u></em>
The graph is given below. It shows the various points plotted and labeled.
The box near the y axis should be labeled gallons [in the tank]
The box under the x axis (if you have such a thing) should be labeled Time in minutes.
