Answer:
1. Yes 2. No 3. Yes 4. No
Step-by-step explanation: 1 is a function because none of the x values repeat, 2 isn't a function because in the x coordinates, -2 repeats, 3 is a function because if you were to draw a (vertical) line through each point, none of them have two points on one line, 4 is a function because none of the x coordinates point to more than one y coordinate

According to PEMDAS
Multiplying/dividing comes first when you read the equation from left to right
Answer:
x= no solution
Step-by-step explanation:
4x-2+x=-2+2x
We first add 4x+x on the left side.
5x-2=2+2x
We then add 2 to both sides.
5x=2x
The answer is no solution because we got no answer out of the equation.
To pay website Alen needs to make 1 kite a day that is 7 kites.
To earn at least 900$ per week he needs to make 900$/20$=45kites

Gas mileage = 30.5 mi/gal
Volume of gas = 1.5 l
Note that 1 liter = 0.264172 gallons
Therefore
1.5 l = (1.5 l)*(0.264172 gal/l) = 0.3963 gal
Distance traveled is (Gas mileage, mi/gal)*(Gal of gas)
= (30.5)(0.3963) = 12.087 mi
Answer: 12 mi (nearest integer)
