The expression 18 - 0.25(18) can be used to find the new price of pillow.
Step-by-step explanation:
Given,
Cost of pillow = $18
Mark down = 25% = 
To find the amount of mark down, we will multiply it with cost of pillow;
Amount of Mark down = 0.25*18
The new price of pillow can be determined by subtracting amount of mark down from the original cost of pillow.
New price = Original Cost of pillow - Amount of mark down
New price = 18 - 0.25(18)
The expression 18 - 0.25(18) can be used to find the new price of pillow.

Answer:
y = 1 , x = 3
Step-by-step explanation:
3x + y = 10
x = 2y + 1
3(2y + 1) + y = 10
6y + 3 + y = 10
7y = 7
y = 1
x = 2(1) + 1
x = 3

ANSWER

EXPLANATION
Since the parabola has the (0, 0) and the directrix at y=2.
The equation is of the form

where (h,k) is the vertex.
The vertex is half way between the directrix and the focus.
The vertex will be at (0,1)
and is the distance from the vertex to the focus which is 1.


1st find the slope m.
m= (rise)/(run). Look up the graph and notice that the rise is 1 for a run =5
Then the slope will be 1/5
2 lines are parallel if they have the same slope so it's either
y= 1/5 x + 4 or 1/5 x + 12/5
our function is y = mx + b, but we know that m = 1/5
so the equation is y = 1/5 x + b
and we know that the function passes through the point (-2,2)
To calculate b, plug in y= 1/5 x + b , x & y by their respective values:
2 = (1/5) (- 2) + b
2 = - 2/5 + b and b = 12/5, then the equation is Y= 1/5 X + 12/5
