Answer:
A is correct
Step-by-step explanation:
Here, we want to write an inequality
If the water level drops by 14 feet
what this mean is that we are subtracting 14 from the original level L
Thus, we have
L-14
Higher than 20 means that we have;
L-14 > 20
L > 20 + 14
L > 34
Just plug in -3 for x. So it will be -(-3)^+ 1
Which is 3^+1.
I'm confused by your ^ sign I'm not sure if this is supposed to be squared or not...? But just solve/simplify the equation.
Hope this helps!
Check your solution by first checking the end point , in the related equation. Pick a value greater than , such as 2, to check in the inequality. Solve for x. Divide both sides by 3 to isolate the variable.
You need to set up a linear graph. One side with gallons and the other with dollars. Point 1 will be at (1500, 2.10). Point 2 (1300, 2.95). Draw a straight line through these points in your graph and your graph will then give you the answers to your other questions.
