Answer:
a 5-point star has rotational symmetry. A 5-point star is a two-dimensional polygon in the shape of a star with five points, or tips.
So symetry will have a total of 360 degrees, then if you divide it by 5 ( the number of point in the star) you will get 72 degrees each so it has 5 reflections
Answer:
28
Step-by-step explanation:
-2+9 (4)=7(4)=28
Answer:
Point-slope form:
y-5= -1/3 times (x+9)
This is only for the first part
It depends. Is this fee for every exhibit? Then it would be:
f(x) = 6x
Otherwise it’s:
f(x) = 2x + 4
Answer:
<h2>b = 4</h2>
Step-by-step explanation:
Put a = -0.1 to the first an second equation and find velue of b:
3 = 10a + b
3 = 10(-0.1) + b
3 = -1 + b <em>add 1 to both sides</em>
4 = b → b = 4
2 = 20a + b
2 = 20(-0.1) + b
2 = -2 + b <em>add 2 to both sides</em>
4 = b → b = 4
