A function can be represented verbally. For example, the circumference of a square is four times one of its sides.
A function can be represented algebraically. For example, 3x+6 3 x + 6 .
A function can be represented numerically.
A function can be represented graphically.
Answer:
B a = 180 -77-60
Step-by-step explanation:
The angles add to 180 degrees since they form a straight line
77+ 60+a = 180
a = 180 -77-60
That would be $1.50 per Gallon
-2x-x+8
Step 1) -2x-1x+8
step 2) (-2-1)x+8
Step 3) -3x+8
Answer: -3x+8 :)
