Answer:
If Shawn downloads a movie at a price of $ 2 each, for five movies he should pay $ 10. A percentage of 25% calculated as a sum is required to pay multiplied by 0.25. If for five downloaded movies there is a discount of 25%, it means that at a price of $ 10 he will have a 25% discount, $ 10x0.25 (25%) and get a discount of $ 2.5. That means he saved $ 2.5 if he bought five movies, and would pay $ 7.5.

Answer:
- f(x) = x
- g(x) = -2x+1
- f(x) -(-g(x)) = -x+1
- f(x) +g(x) = -x+1
- f(x)-(-g(x)) = (f+g)(x) is true for all functions f and g, linear or not
Step-by-step explanation:
We can define a couple of linear functions as ...
f(x) = x
g(x) = -2x+1
Then the reflected function -g(x) is ...
-g(x) = -(-2x +1) = 2x -1
And the difference from f(x) is ...
f(x) -(-g(x)) = x -(2x -1) = -x +1 . . . . f(x) -(-g(x))
We want to compare that to the sum of the functions:
f(x) +g(x) = x +(-2x +1) = -x +1 . . . . f(x) +g(x)
The two versions of the function expression have the same value.
These results are <em>a property of addition</em>, so do not depend on the nature of f(x) or g(x). They will hold for every function.
Answer: -x + 1173
Step-by-step explanation:
23 (3 + 48) - x
23 x 3 = 69 and 23 x 48 = 1104
(69 + 1104) - x
69 + 1104 = 1173
1173 = -x or -x = 1173
Hey! I got you! So this is an arithmetic equation, and the common difference (how much it goes up by) is positive three. To find a sub 0- the first number of the sequence, you’ll subtract the first number shown by 3! This will show you 33! Now you input this into an equation and your answer will be 3n+33!

Answer:
Step-by-step explanation:
If the ratio of the sides is 13:14:15, we can say that the length of each side is 13x, 14x and 15x.
Then, if the perimeter is 84 m, we have:
The length of each side is:
Now, to find the area of the field, we can use the following formula:
Where a, b and c are the sides and p is the semi perimeter:
So we have that:
