Answer: y = 3
Step-by-step explanation:
Two lines are said to be parallel if they have the same slope. All we need to do is to find the slope of each line . The formula for finding slope is given as :
m =
For the first line
= 11
= 2
= y
= 0
substituting into the formula , we have
m =
m =
m =
Also Finding the slope of the second line we have
=
=
=
Since the two lines are parallel , we will equate their slope , that is
=
3y = 9
y = 3
The solution is
The number of vanilla cone she christina's sold after 20 day is 138.
Christina's ice cream parlor sold 60 vanilla cones on the first day of summer.
If the goal is to increase the number of vanilla cones sold each day by 4
Arithmetic progression is the series of number that have common difference between adjacent numbers.
Christina sold 60 vanilla cone at her first day. a=60
now each day is sells increase by 4 cones
so we common difference D = 4
The progression can be given as
S = a + (n-1)D
for 20th day = 60+(20-1)4
= 138
Thus the required number of vanilla cone she christina's sold after 20 day is 138.

Answer:
formula: 60x4(to the power of 20)
The vertex is
nothing. (Type an ordered pair.)
Answer:
Vertex = (-1, 0)
The axis of symmetry is x = -1
Minimum point is (-1, 0)
Range is y ≥ 0
In the interval notation [0, ∞)
Step-by-step explanation:
The given function is y = x^2 +2x + 1.
Write the given equation in the form of y = (x -h)^2 + k.
Here (h,k) is the vertex.
y = x^2 + 2x + 1
y = (x + 1)^2
Vertex = (-1, 0)
Axis of symmetry
The axis of symmetry splits the parabola in 2 equal parts.
In this equation, the axis of symmetry is x = -1
Maximum/minimum value
The parabola goes maximum when there is negative sign, it goes minimum when there is positive sign.
Here we have positive sign in front of (x + 1)^2, therefore, it is minimum at
y= 0
When y =0, x = -1
Therefore, minimum point is (-1, 0)
Range
Y- axis represents the range.
Here the minimum is 0, the maximum goes upto infinity.
Range is y ≥ 0
In the interval notation [0, ∞)
Herewith I have attached the graph of the function.
Answer:
Step-by-step explanation:
The equation of a vertical line through an ordered pair is given by:
The given ordered pair is (-6,-1).
The x-value of this ordered pair is -6.
Therefore the equation of the line that is a vertical line that passes through(-6, -1) is
