Step-by-step explanation:
use the Pythagorean theorem
Answer:
1.3(2)^t
Step-by-step explanation:
1.3(2)^t
You start with 1.3 because that is your inital amount, then you multiply by 2 because it doubles, and your exponent will be t (the number of weeks)
Answer:
The equation of your line is y=1x+2
Step-by-step explanation:
first you take y2-y1/x2-x1
y2=-1 y1=5
x2= -3 x1= 3
that gives you your slope so (-1-5)/ (-3-3) = 1
y=mx+b
mx is your slope
y=1x+b
to solve for b you input your slope and one of your points (I used (3,5)
5=1(3) +b
solve for b and you get 2
then put your mx and b into the equation of a line
y=1x+2
and thats your answer
You can also check your work by using a graphing calculator and checking that the line goes through those two points.
