The answer is X^2-xy+2x^2y sorry if I am wrong
Answer:
This relationship is a function
Step-by-step explanation:
While a function may not have two output values (y) assigned to the same input value (x), it may have two input values (x) assigned to the output value (y).

Answer: 14gallons
Step-by-step explanation:
12gallons/144miles = 1gallon/12miles
Therefore 6gallons = 12*6 = 72miles.
In order to cover 240miles, she will need 240/12 = 20gallons.
20-6 = 14gallons
She will need 14gallons of gas more.
Answer:
y=2x-23
Step-by-step explanation:
m=(-9+7)/(7-8)=-2/-1=2
y=2x+b
-7=2(8)+b
-7-16=b
b=-23
y=2x-23
