A right angle is formed by two rays
extending from a common point. Seven
more rays are then drawn
inside the right angle.
What is the total number
of angles, of all sizes, that
are formed by the rays?
Answer:
Vertex.
Step-by-step explanation:
An angle can be defined as a figure formed by two rays with a common endpoint. The two rays are called the sides of the angle. The common endpoint is called the vertex.

Kayla drove 13 miles in 20 minutes. What's her average rate in miles per hour
Answer:
39 MPH
Step-by-step explanation:
d = rt
13 times 3,
20x3=60.
60=1 hour
13M = every 20m
60 divided by 20 =3.
13 times 3 = 39.
39MPH
Kayla is driving at 39 miles per hour.
What is average?The average is calculated as the product of all values divided by all possible values. It can also be described as mean. The mean in statistics is the average value for the particular sample or collection of data. It is determined by dividing the total number of observations by the total number of observations.
Given:
Kayla drove 13 miles in 20 minutes.
To find the average rate in miles per hour:
Miles / hour
= 1 / 1
Multiply by 3 to the rate,
So, 13 x 3 mils in 3 x 20 minutes.
39 miles per hour.
Therefore, the average rate is at 39mph.

Explanation:
Recall that vertex form is
y = a(x-h)^2 + k
where (h,k) is the vertex. We want the vertex to be (-3,0) which means that h = -3 and k = 0 must be the case.
Plug those values in to get
y = a(x-h)^2 + k
y = a(x-(-3))^2 + 0
y = a(x+3)^2
Now we need the value of 'a', which determines two things
How vertically stretched or compressed the graph is, and,If the parabola opens upward or downward. We have a > 0 for upward and a < 0 for downward.To determine 'a', we'll use the other point (-5,-4).
So we'll plug in x = -5 and y = -4 and solve for 'a'
y = a(x+3)^2
-4 = a(-5+3)^2
-4 = a(-2)^2
-4 = a(4)
-4 = 4a
4a = -4
a = -4/4
a = -1
The equation y = a(x+3)^2 updates to y = -1(x+3)^2 which simplifies to the final answer y = -(x+3)^2. The answer is choice D.
---------------
As a check, plugging x = -5 should lead to y = -4
y = -(x+3)^2
y = -(-5+3)^2
y = -(-2)^2
y = -(4)
y = -4
This helps confirm the answer.
I'll let you check to see if (-3,0) is on this graph. Plugging in x = -3 should lead to y = 0.

Point M is the midpoint of line segment BC. If the coordinates of Mare (-1,1) and the coordinates of B are (3,4), find the coordinates of Point C
a(-5,-2)
b(7,7)
c(2,5)
b(1,5/2)
Answer:
a(-5,-2)
Step-by-step explanation:
The midpoint of a segment
Given points C(xc,yc) and B(xb,yb), the coordinates of the midpoint M can be found knowing that:
[tex]\overline{CM} = \overline{ MB}[/tex]
Applying that relation in both axes separately, we can write:
[tex]\displaystyle x_m=\frac{xc+xb}{2}[/tex]
[tex]\displaystyle y_m=\frac{yc+yb}{2}[/tex]
Knowing the coordinates of the midpoint and B, we can find the coordinates of the other extreme C solving both equations for the required variable:
[tex]x_c=2x_m-x_b[/tex]
[tex]y_c=2y_m-y_b[/tex]
Plugging in the known values: M=(-1,1) and B=(3,4):
[tex]x_c=2*(-1)-3=-2-3=-5[/tex]
[tex]y_c=2*1-4 = 2-4=-2[/tex]
The coordinates of C are (-5,-2)

Step-by-step explanation:
any line parallel to another line has the exact same slope. So you already know your slope, but to do this, we need point slope form. y-y_1=m(x-x_1). we can plug in the slope as well as well as the point that we know. y+3=1/2(x-4).

On a coordinate plane, an absolute value graph has a vertex at (negative 1, negative 3).
Which function is represented by the graph?
f(x) = |x – 1| + 3
f(x) = |x + 1| – 3
f(x) = |x – 1| – 3
f(x) = |x + 1| + 3
Answer:
The answer should be B
Step-by-step explanation:
I got it right on edge
The function f(x) = |x + 1| – 3 is represented by the graph.
How do we determine the vertex of the graph of an absolute function?In the graph of an absolute function given by (x - a) +b, the vertex is given by (a, -b)
We can find the function that is represented by the graph, as follows:Let's take the first function, f(x) = |x – 1| + 3. Its vertex is given by (1, 3) by using the rule.
Now let's take the second function, f(x) = |x + 1| - 3. It's vertex is given by (-1, -3) by using the rule.
Now let's take the third function, f(x) = |x - 1| - 3. It's vertex is given by (1, -3) by using the rule.
Now let's take the fourth function, f(x) = |x + 1| + 3. It's vertex is given by (-1, 3) by using the rule.
From this, we can see that the second function has a matching vertex.
Therefore, we have found that the absolute function f(x) = |x + 1| – 3 is represented by the graph.
