Answer:
72 miles.
Step-by-step explanation:
If he uses 6 gallons of gas, you would do 6 (gallons he used) x 12 (miles per gallon) equaling 72.
 
        
             
        
        
        
Find the inside angle B of the smaller triangle using the base (4) and height (6)
smaller part of B =  arctan(4/6) = 33.69 degrees
 full B = 90 degrees - smaller B gives you the other part of B for the left hand side
so 90 - 33.69 = 56.31
now AD =  6 x tan(56.31) = 9 feet
 answer is G
        
             
        
        
        
Answer:
Linear Decreasing
Step-by-step explanation:
Exponential graphs are curved, but this line is straight, so it's linear. It's decreasing since the graph moves from left to right, and as you can see, the line starts from the left tall but gradually goes lower as it goes towards the right.
 
        
                    
             
        
        
        
Answer:
(-4,2)
Step-by-step explanation:
First we have to find a common multiple to use to add and find the system of equations. We need to eliminate one of the variables in order to solve.
Since 5 * 3 = 15, and 3 * -5 = 15, -15x and 15x will cancel each other out. Therefore x will be eliminated.
Before:
5x + 2y = -16
3x + 7y = 2 
After:
15x + 6y = -48   <----------Now we solve for y
-15x + -35y = -10
+----------------------
-29y = -58
-29      -29
y = 2
Now what we do is we choose and equation and solve for x, since it is still unknown. Any equation is fine but I will choose the second one since it has easy numbers.
3x + 7y = 2
3x + 7(2) = 2
3x + 14 = 2
    -14     -14
----------------------
3x = -12
3        3
x = -4
Therefore our final answer is (-4,2)
