Answer:
y = -5/4x - 8
Step-by-step explanation:
Slope = m = -5/4
y = -5/4x + c (or b, depending on where you're from)
You can sub (-8, 2) and (-4, -3) into y = -5/4x - c and both are the same to where c = -8
Therefore, the equation is = y = -5/4x + (- 8)
= y = -5/4x - 8

Answer:
![a_n=\dfrac{1}{2}n^3-\dfrac{1}{2}n^2+6n-3](https://tex.z-dn.net/?f=a_n%3D%5Cdfrac%7B1%7D%7B2%7Dn%5E3-%5Cdfrac%7B1%7D%7B2%7Dn%5E2%2B6n-3)
Step-by-step explanation:
The first differences are 8, 13, 21. The second differences are 5, 8. The second differences are not constant, so this is <em>not a quadratic sequence</em>.
If we assume it is a cubic sequence, a calculator tells us the formula is ...

Answer:
a medium smoothie cost $3.25
Step-by-step explanation:
j = 4.95 which is the cost of one jumbo
equation from word problem
2j + m = 4m + 0.15
subtract m from both sides
also subtract 0.15 from both sides
2j - 0.15 = 3m
substitute j
2(4.95) - 0.15 = 3m
9.75 = 3m
m = 3.25 or $3.25
