Answer:
= - ![\frac{7}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B16%7D)
Step-by-step explanation:
The n th term of a geometric sequence is
= a![r^{n-1}](https://tex.z-dn.net/?f=r%5E%7Bn-1%7D)
where a is the first term and r the common ratio
here a = 14 and r =
= -
, hence
= 14 ×
= 14 × -
= - ![\frac{7}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B16%7D)
Answer:
if she goes 5 days a week then she will pay 45 dollars
she only had 2 pay 20$ one time and she pays 5 dollars each visit and she goes 5 times a week
5x5 is 25 and plus 20 will be 45 just within only that weel
Answer:
point slope form:
y - 3 = -4/3(x- (-1))
slope intercept form:
y = -4/3x + 13/3
Step-by-step explanation:
So if the points are (7, -4) and (-1,3) then we can use those points to figure out the slope.
y2-y1/x2-x1 is the forumla for the slope
3-7/ -1 - (-4) --> -4/-1+4 --> -4/3
point slope form:
y - y1 = m(x-x1) ~ you can choose either of the two points to use, you should get the same answer
y - 3 = -4/3(x- (-1))
y - 3 = -4/3x+4/3
add 3 to both sides
y = -4/3x + 13/3 ~ slope intercept form
