Answer:
-8-60p
Step-by-step explanation:
Answer: Side BC has a length of square root 10 units
Step-by-step explanation: I just took the test
X+y=14 (*25)
35x+25y=410
---------------------
35x+25y=410
25x+25y=350
---------------------
10x=60
x=6
For the first day we have the following function:
f (n) = (0.3 * 10) n + 8
For the second day we have the following function:
f (n) = (0.4 * 10) n + 5
You spent the same amount of money as the day before:
(0.3 * 10) n + 8 = (0.4 * 10) n + 5
3n + 8 = 4n + 5
n = 8-5
n = 3 items
We evaluate each function for n = 3
f (3) = (0.3 * 10) * 3 + 8 = 17 $
f (3) = (0.4 * 10) * 3 + 5 = 17 $
The total amount of money is:
17 + 17 = 34 $
Answer:
you purchase 6 items
you spend at the craft store during the sale $ 34
F(3) is 3 since the equation of the line is f(x)=3
