Answer:
A rectangle has rotational symmetry of order 2.
Step-by-step explanation:
The rotational symmetry involves rotation.
The rotational symmetry of order is the number of times a shape is mapped onto itself during a 360° rotation.
A rectangle has rotational symmetry of order 2.
When a rectangle is rotated on 180° or 360° it is mapped onto itself.
C(b) = 2.75b + 10
This is based of the f(x) = mx + b formula, where m is the slope, x is the variable (or input) and b is the y intercept. In this circumstance the slope is 2.75, so we change m for 2.75. The variable is the amount of books so we change it for b (like it says in the word problem), and and 10 is the starting cost, so it’s the y intercept, so we change b for 10.
Hope this helps! Please make me the brainliest, it’s not necessary but appreciated, I put a lot of effort and research into my answers. Have a good day, stay safe and stay healthy.
Answer:
0.35
Step-by-step explanation:
.5x.7
3: 3,6,9,12,15,18,21,24,27
7: 7,14,21,28,35
Answer:
$10, $20, $30
Step-by-step explanation:
So, the equation you have set up already, y = 2x + 10, models the cost of the membership and movies, with y as the total cost, and x as the number of movies. Here we can just plug in the x values to get the total costs. If x is 0, we get $10 total, if it is 5, we get $20 total, and if it is 10, we get $30 total.
