Answer: Unit price = 0.2 per ounce
Step-by-step explanation:
What we were given;
Product price = $4
Quantity of product = 20 ounce
To get the unit price of the strawberry jam,
We simply devide the product price by the quantity of the product
Therefore;
Unit price = 4 / 20
Unit price = 0.2 per ounce
4x-2y=8 ==> y=2x-4 (to better show you what I mean)
2 lines are parallel if they have the same slope (m the coefficient of x).
So y=mx + b // y =2x-4 means m=2 & y=mx + b, becomes y=2x + b.
Moreover they are telling us that this function passes by (-2,1), where -2 represents x & 1, represents y. To calculate b , replace x & y by their values:
y=2x+b ==> 1 = 2(- 2) + b==> 1 = -4 + b ==> b= 5. Finally the equation is
y=-2x+5
Answer:
$2.50
Step-by-step explanation:
The taxes are figured as follows: 0.089(value of car)
Here the taxes are 0.089(value of car) = $1100.
Divide both sides of this equation by 0.089 to determine the value of the car.
value of car = $12359.55, or approx $12360.
