Answer:
y = 9x
Step-by-step explanation:
You can set up linear equations like this: y = mx + b, where m is the slope or rate, and b is the y-intercept.
9 would be the slope, since he has to pay $9 per gift.
The y-intercept is when x = 0, but if he doesn't buy any gifts, he won't have to pay anything, so b = 0. You don't have to include it since it's 0.
So, it's just y = 9x
Hope that helps! :D
Answer:
273.94 hours.
Step-by-step explanation:
1 day = 0.75 hours of practicing in a day.
365.25 = x
1/365.25 = 0.75/x Cross multiply
x = 0.75 * 365.25 Combine
x = 273.94 hours
The range of y=e^x+1 is y>1.
X+0.5 could be an inequality to represent the possible weight of the second fish, unless you can tell me the weight of the first fish?
Answer:
These numbers are - parameters.
Step-by-step explanation:
A study of all the students at a small college showed a mean age of 20.9 and a standard deviation of 2.9 years.
These numbers are - parameters.
These numbers are parameters as they are for all the students, and merely not a sample.
