Answer:
78 dollars
Step-by-step explanation:
Function c is defined by the equation c(n) = 50 + 4n. It gives the monthly cost, in dollars, of visiting a gym as a function of the number of visits, n. Find the value of c(7).
Given:
c(n) = 50 + 4n
Where,
c = monthly cost of visiting a gym
n = number of visits
Find the value of c(7)
That is, when n = 7
c(n) = 50 + 4n
c(7) = 50 + 4(7)
= 50 + 28
= 78
c(7) = 78 dollars
Answer:
-2
Step-by-step explanation:
5 to the 2nd power is 25 and a number to a negative power is 1/number^power
What is it that you need help with?
First you have to multiply -2 and 2 which is -4x.
Then your going to distribute -4 to 4x which is -16x.
Now your going to distribute -4 and -3 which is 12.
So your simplified expression would be -16x + 12
Your answer would be A. positive linear association.
If we break this phrase down, we first get "positive", which we can see is true here as the graph is ascending towards the top right, that is, going upwards and 'forwards'. This is how we recognise lines with positive slopes, such as 3x or (1/2)x.
The word "linear" means a straight line, you can sort of see the word "line" in it, and so this is also true as the trend line is straight.
I hope this helps!
