Answer:
The answer in the procedure
Step-by-step explanation:
we have
2x-3y=-1 ----> equation A
3x+3y=26 --> equation B
Solve the system by elimination
Adds equation A and equation B
2x-3y=-1
3x+3y=26
----------------
2x+3x=-1+26
5x=25
x=25/5
x=5
Find the value of y
substitute the value of x in equation A or equation B and solve for y
2(5)-3y=-1
10-3y=-1
3y=10+1
y=11/3
The equation produces a straight line.
Answer:
.
Step-by-step explanation:
(3 , -4) ; slope(m) = 2/3
y - y1 = m (x -x1)
![y - [-4] = \frac{2}{3}(x - 3)\\\\y + 4 = \frac{2}{3}x - 3*\frac{2}{3}\\\\y +4 = \frac{2}{3}x-2\\\\ y = \frac{2}{3}x - 2 - 4\\\\ y = \frac{2}{3}x - 6](https://tex.z-dn.net/?f=y%20-%20%5B-4%5D%20%3D%20%5Cfrac%7B2%7D%7B3%7D%28x%20-%203%29%5C%5C%5C%5Cy%20%2B%204%20%3D%20%5Cfrac%7B2%7D%7B3%7Dx%20-%203%2A%5Cfrac%7B2%7D%7B3%7D%5C%5C%5C%5Cy%20%2B4%20%3D%20%5Cfrac%7B2%7D%7B3%7Dx-2%5C%5C%5C%5C%20%20y%20%3D%20%5Cfrac%7B2%7D%7B3%7Dx%20-%202%20-%204%5C%5C%5C%5C%20%20%20y%20%3D%20%5Cfrac%7B2%7D%7B3%7Dx%20-%206)

Answer:
1). Fold reflection symmetries = 5
2). Order of rotational symmetries = 10
3). Smallest angle of rotational symmetry = 36°
Step-by-step explanation:
A decagon has number of fold reflection symmetries = 5
[Fold reflection symmetries are the lines by which we can fold the shape into half]
Order of rotational symmetry of a decagon = 10
[Order of rotational symmetry means number of rotations by which the polygon maps itself in a complete rotation of 360°]
Smallest angle of rotational symmetry for a decagon
= 
=
= 36°
