13.50 per set
+.45 per day value
she got 20 sets
5 days after would be
13.50 ×20=270
value of 20 sets at 13.50 a set on day one was 270.00
.45×20=9.00
the 20 sets gain 9 dollars a day
9×5=45
9 dollars a day times 5 days is 45 dollars
45+270=315

Answer:
The option on the top left
Step-by-step explanation:
As the equation is 
We know that the circle will have a radius of 4 and will be shifted 4 units up
Answer:
12units²
Step-by-step explanation:
Given a triangle that has sides that measure 2 units, 5 units, and 5.39 units,
Perimeter of the triangle = 2 + 5 + 5.39
Perimeter of the triangle = 12.39units
since the circumference is equal to the perimeter of the triangle, hence;
C = 12.39units
C = 2πr
r is the radius of the circle
12.39 = 2(3.14)r
12.39 = 6.28r
r = 12.39/6.28
r = 1.973 units
Get the area
Area = πr²
Area of the circle = 3.14(1.973 )²
Area of the circle = 3.14(3.892)
Area of the circle = 12.22units²
Area of the circle ≈ 12units²
Point slope form:
(y-y1) = m (x-x1)
m=slope=1/2
given point (x1,y1) = (-2,7)
(y-7) = 1/2 (x+2)
slope intercept form:
y-7 = 1/2x + 1
y = 1/2x + 8
ANSWER: y=1/2x + 8
