Answer:
A = 5.5t + 9
Step-by-step explanation:
We assume that the relationship between t and A is linear.
We have two points on a line: (2, 20) and (4, 31).
We now find the equation of the line.
A = mt + b
m = (31 - 20)/(4 - 2) = 11/2 = 5.5
20 = 5.5(2) + b
20 = 11 + b
b = 9
A = 5.5t + 9
The Solution.
The given points are
The formula is
In this case,
Therefore,
Hence, the correct answer is (-1, 4) (option 3)
Hello!
First, you will need to subtract -2 from 4 (4-(-2)). You'll need to do this because to find the slope, you'll need to subtract y² w/ y1 or 4-(-2) and divide it by x² - x1 or -1-(-3). So once you set up the equation it'll look like this...
4-(-2)/-1-(-3)
Now after you've subtracted the numbers, your equation will look like this...
6/2
You'll then divide 6 by 2 and your slope will be 3
I hope this helps!
Answer:
c = -400
Step-by-step explanation:
-2/5c -8 = 32
-2/5c = 40 add 8 to both sides
c = -400 multiply both sides by the opposite reciprocal, -5/2
