Answer:
17
Step-by-step explanation:
an=a1+(n-1)d
a22=-25+21(2)
a22=17
Hey!
Our point slope formula is y-y1 = m(x-x1)
Therefore, we can plug our values from the slope and the set of points.
We have:
y-7 = -3/2(x--4)
Subtracting a negative is the same thing as adding, so we have:
y-7 = -3/2(x+4)
Hope this helps!
<u>Answer:</u>
(x,y)→(y,x); A' is at (2, −7)
<u>Step-by-step explanation:</u>
According to the given image, the coordinates of the kite ABCD are:
A (-7, 2)
B(-5, 3)
C(-2, 2)
D(-5, 1)
Kite ABCD is then reflected over the line y = x, the main rule to find the coordinates of the images is (y, x).
So for point A (-7, 2), the coordinates of the point A' after reflecting over the line y=x will be A' (2, -7).
Answer:
The sum of interior angles of given polygon is 900°
Step-by-step explanation:
A regular polygon is a n-sided figure with n sides and the length of all sides is same.
In the diagram, we have a polygon with 7 sides.
The formula given is used to calculate the sum of interior angles of a polygon
Here n is the number of sides of polygon
In the given polygon
n = 7
So,
Hence,
The sum of interior angles of given polygon is 900°
To find this , just replace the x with the 3
g(3)=3^2
which equals 9
answer: 9
