-
→ Equation 1 (
)
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope of the line and "b" is the y-intercept.
Knowing this, and having the equations provided in the exercise, you can identify the slope and the y-intercept of each line.
- In Equation 1:
- In Equation 2:
- In Equation 3:
Answer:
17.5 milies
Step-by-step explanation:
80/4
=20/1
This means that Ivan can walk 1 mile in 20 minutes
To figure out how many miles Ivan can walk in 345 if she continues at that pace you divide 345 by 20
345/20 = 17.5
This means Ivan can walk 17.5 milies in 345 minutes
Answer:
20,176,803
Step-by-step explanation:
This geometric series has a first term of 3 and a common ratio of 21/3 = 7. The formula for the sum of n terms of a series with first term a1 and common ratio r is ...
Sn = a1·(r^n -1)/(r -1)
For a1=3, n=9, and r=7, the sum is ...
S9 = 3·(7^9 -1)/(7 -1) = 3·40353606/6 = 20,176,803
The sum of the first 9 terms is 20,176,803.
_____
The first 9 terms are ...
3 +21 +147 +1029 +7203 +
50,421 +352,947 +2,470,629 +17,294,403
Hopefully this helps, and sorry I didn't do 8 I'm limited on time
