x − y = 0 = difference
x + y = 4 = sum
Can be solved by the sum and difference rule (most of the time without pen and paper)
x=(sum+difference)/2=0+4/2=2
y=(sum-difference)/2=(4-0)/2=2
This is what my calculator says
Answer:
Just divide
400/54=7.40
7.4 meters per second
hope this helps
Step-by-step explanation:
Answer:
y = 4
Step-by-step explanation:
An exponential function in standard form is
y = a 
Use ordered pairs from the table to find a and b
Using (0, 4), then
4 = a
( note that
= 1 ), so
a = 4, then
y = 4 
Using (1, 8)
8 = 4
= 4b ( divide both sides by 4 )
b = 2
y = 4
← represents the values in the table
