Answer:
3/4 or .75
Step-by-step explanation:
find two sets of coordinates on the grid. I choose 60,40 and 20,10. then first you subtract the y coordinates so 40 -10 which is 30 next you subtract the x coordinates so 60-20 which is 40 so your fraction is 30/40 which simplifies to 3/4 which as a decimal is .75
Answer:
A
Step-by-step explanation:
y bar basically means the average of the y-values.
To get the average, we add up all the y-values in the table and divide by the total number of values (here we have 5 values). Hence,
y bar = 
correct answer is A
Answer:
-5
Step-by-step explanation:
Using rules of exponents we can change this equation to
y ^ (-9 * b) = y^45
-9*b = 45
b = -5
