multiply 12 and 16 then multiply 8 and 10 then add them up to get 15,360
Answer:
The linear function is equal to ![f(x)=-25x+850](https://tex.z-dn.net/?f=f%28x%29%3D-25x%2B850)
Step-by-step explanation:
Let
y -----> the number of tickets remaining at a given time
x -----> the time in days
we know that
The linear equation in slope intercept form is equal to
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
where
m is the slope and b is the y-intercept (original number of tickets)
In this problem we have
----> is negative because is decreasing
substitute
![y=-25x+850](https://tex.z-dn.net/?f=y%3D-25x%2B850)
Convert to function notation
![f(x)=-25x+850](https://tex.z-dn.net/?f=f%28x%29%3D-25x%2B850)
Answer:
10.3
Step-by-step explanation:
![\sqrt{ { ( 8 - ( - 1))}^{2} + {( - 2 - 3)}^{2} } = \sqrt{ {9}^{2} + {( - 5)}^{2} } = \sqrt{81 + 25} = \sqrt{106} = 10.3](https://tex.z-dn.net/?f=%20%5Csqrt%7B%20%7B%20%28%20%208%20-%20%28%20-%201%29%29%7D%5E%7B2%7D%20%2B%20%20%7B%28%20-%202%20-%203%29%7D%5E%7B2%7D%20%20%7D%20%20%3D%20%20%5Csqrt%7B%20%7B9%7D%5E%7B2%7D%20%20%2B%20%20%7B%28%20-%205%29%7D%5E%7B2%7D%20%7D%20%20%3D%20%20%5Csqrt%7B81%20%2B%2025%7D%20%20%3D%20%20%5Csqrt%7B106%7D%20%20%3D%2010.3)

Step-by-step explanation:
These problems are about like terms. Those are terms that are alike (same variables) but the coefficients (numbers in front) can be different.
1. 12m + 24m = 36m
2. 90a - 30a = 60a
Example: 6k + 8k + 10 = 14k + 10 (the part of the expression that's just a number does not combine with the parts that have variables).
3. 29b + 8
4. 36d + 25 (the terms with d in them combine--they don't have to be back-to-back)
5. This is about the Distributive Property; first multiply 14 + 15f both by 3, then look for opportunities to combine like terms.
3(14 + 15f) + 79 = 42 + 45f + 79 = 121 + 45f
6. 20(18 + 5t) - 47 + 28t = 360 + 100t - 47 + 28t
= 313 + 128t
