Answer:
The greater unit rate of the two functions is the first function shown by the table and the greater y intercept is the second function shown by the graph.
Step-by-step explanation:
Find the slope of both equations
(15-5)/(5-0) = 2
(6-0)/(0+4) = 3/2
2>3/2
y-intercept is where the function crosses the y axis, function 1 y-intercept is 5 and the y-intercept of function 2 is 6, 6>5
You find the mean by adding each value then dividing the sum by the number of values there were so in this case you'd say 301 + 222 + 287 + 310 + 346 which is 1466 then divide by 5 because there are 5 values and your answer is 293.2!
I hope this helps
9.) Answer: B. f(x) = 4 - x
Explanation/Proof:
If we substitute, the answers are correct.
f(x) = 4 - (1)
f(x) = 3 ✅
f(x) = 4 - (2)
f(x) = 2 ✅
And so on and so forth.
The formula for the sum of n terms in an arithmetic progression is:
S = n/2 * (2a + (n-1)d)
Here, the common difference, d, is 8 and the first term, a, is 1. Substituting these into the formula, we get:
S = n/2 * (2*1 + 8(n - 1))
S = n + 4n² - 4n
S = 4n² - 3n
The answer is A.
