111) 5:4
112) 3.6
113) -4
114) 0.3 units down, 0.4 units to the left
Answer:
-1
Explanation:
Let the number be x.
Then the equation will be:
3(x+18) = 51
=> 3x + 54 = 51
=> 3x = 51 - 54
=> 3x = -3
=> x = -3/3
=> x = -1
So, the number you thought of is -1.
The answer is A, all that was needed was to do the math.
Not sure what alive by graphing means, but these are the equations on a graph. Red is y=4x+7 and blue is y=-3x.

Answer:
B)
Step-by-step explanation:
A function is when every input has one output.
Easiest way is to do the "vertical line test" and "horizonal line test."
Basically you draw a vertical line and a horizontal line.
If either line passes through more than one point, then it is not a function.
The only one that passes them is B, the line.
