Answer:
x=1
Step-by-step explanation:
x=-b/(2a)
a=2
b=-4
c=2
-(-4)/(2*2)=4/4 or 1
x=1
Answer:
k = 1
Step-by-step explanation:
<u>Discriminant</u>
As we need to determine the value of k that will give <u>one solution</u>, set the <u>discriminant to zero</u>.
<u>Given equation</u>:
Therefore:
Substitute these values into the discriminant and solve for k:
4x+2(-2x+1)=-3
4x-4x+2=-3
2=-3 is not a true statement.
The answer is no solution
Answer:
- $2.79 per bottle
- $0.186 per ounce
Step-by-step explanation:
When you talk about "unit price," you need to define the unit of interest. Unit prices on grocery store shelves don't always use the same unit, even for like items. Here it might be convenient to use any of the following as the "unit":
- 1 bottle
- 1 ounce
- 1 pint (16 ounces)
- 1 cup (8 ounces)
The "unit price" is computed as ...
unit price = (price for some number of units)/(the number of units)
The "number of units" may be larger, smaller, or equal to 1.
Then the price per cup (8 ounces) would be ...
unit price = (price for 15 oz)/(15/8 cups) = ($2.79)(8/15)
= $1.488 per cup
__
The price per ounce would be ...
unit price = ($2.79)/(15 oz) = $0.186/oz
__
We assume that the unit of interest is probably 1 ounce, but it could be something else. Your grader may expect the value to be rounded to the nearest cent, $0.19 per ounce.
X = Amount paid one hour
205.25 - 59 = 146.25
3.25x = 146.25
x = 146.25 ÷ 3.25
x= 45
