Ok so you would times 8.4*10 and get 84-6 which is 78, and 6.5*10 which is 65-6, so then you get 78+59=137 :)
Answer:
2=3
Step-by-step explanation:
Answer:
y-4 =-1(x+1) point slope form
y-2 = -1(x-1)
y = -x +3 slope intercept form
Step-by-step explanation:
We have 2 points, we can find the slope
m = (y2-y1)/(x2-x1)
= (2-4)/(1--1)
(2-4)/(1+1)
-2/2
=-1
The slope is -1
Then we can use point slope form to find an equation
y-y1 =m(x-x1)
y-4 = -1(x--1)
y-4 =-1(x+1) point slope form
Using the other point
y-2 = -1(x-1)
Distribute the -1
y-2 = -1x +1
Add 2 to each side
y-2+2 = -x+1+2
y = -x +3 slope intercept form
A. F(n) = 3n + 5 is your answer
Plug in the corresponding number to n to get F(n).
When n = 0:
3(0) + 5 = F(n)
0 + 5 = F(n)
F(n) = 5 (True).
When n = 1:
3(1) + 5 = F(n)
3 + 5 = F(n)
F(n) = 8 (True).
When n = 2:
3(2) + 5 = F(n)
6 + 5 = F(n)
F(n) = 11 (True)
etc. etc.
hope this helps
There are any number of ordered pairs that work for this equation. Below are some examples.
(0, -18) (2, -10) (5, 2)
In order to find these and any others, you simply select a value for x and plug into the equation to find y. Below is an example.
y = 4x - 18
y = 4(0) - 18
y = 0 - 18
y = -18
(0, -18)
