This graph does not represent a function because the x-intercepts repeat themselves several times. In order for a graph or group of coordinates to be a function, there must be only one of a particular x-coordinate.
Option D. 2(n + 9) is the right answer
Step-by-step explanation:
The word problems are converted into mathematical problems to solve simply.
for the given problem
"two times the sum of a number and 9"
Let n be a number then
when there is and between two things they are performed first then next operation is performed so
the sum of a number and 9
Then
two times the sum of a number and 9
Hence,
Option D. 2(n + 9) is the right answer

To find the total cost of Mikayla's purchase, we add together the costs of the skirts and tops. The costs of the skirts can be found be multiplying the quantity bought by the cost per skirt. Same goes for the tops.
5x + 3(9)
Simplified:
5x + 27
Answer:
Step-by-step explanation:When a quadratic function is graphed in the coordinate plane, the resulting parabola and corresponding axis of symmetry are vertical. The graph of the parabola represented by the quadratic function y = a( x - p )2 + q has an axis of symmetry represented by the equation of the vertical line x = p.

Circumference = πD
------------------------------------------------------
Find Diameter
------------------------------------------------------
10π = πD
D = 10 ← divide by π on both sides
------------------------------------------------------
Find Radius
------------------------------------------------------
Radius = Diameter ÷ 2
Radius = 10 ÷ 2
Radius = 5
------------------------------------------------------
Answer: Radius = 5 units
