A) 110/21 = 5 5/21
B) 10
C) 21/4 = 5 1/4
D) 16/5 = 3 1/5
Recursive equation would be f(x+1) = f(x) - 25 with f(0) = 300
Explicit equation would be f(x) = -25x + 300
And graph would looks like this:
Answer:
100 - 75 = 25%
25%=119.60
need to find 1%
25/25=1%
119.60/25=1%
1%=4.784
now multiply by 100 to find original price
100% = 478.40
original price £478.40
Answer:
The answer is 15 Shirts
Step-by-step explanation:
We want to know what x is going to equal that makes the equation the same.
First, I make the euations equal to each other by substituting the y -->
7x + 50 = 10x + 5
Then, I combine my similar terms --> 45 = 3x
After that, I divide by 3 to get x on its own -->
--> 15 = x
This means that after 15 Shirts are sold, the costs for both companies are the same.
Answer:
x = 13
Step-by-step explanation:
1. 4x + 1 = 8x - 51
2. 4x = 8x - 52
3. -4x = -52
4. x = 13
