Answer:
= -x^2 +x
Step-by-step explanation:
(x) = 1 - x^2
g(x) = 1-x,
(f-g)(x) = 1-x^2 - ( 1-x)
Distribute the minus sign
= 1-x^2 -1 +x
Combine like terms
= -x^2 +x
Answer:
Using the info you just gave,
Basketball, 8 studentsfootball, 7 studentsSoccer 12 studentsother, 13 students
We can now figure out the percentage of students that did NOT select soccer.
First, you need to add all the students together.
8 + 7 + 12 + 13
You get 40 students all together.
Now, add together the students that DID NOT choose soccer.
7 + 8 + 13 = 29
That means that 28/40 of the students did not choose soccer.
Now, convert that to a percentage.
28/40 = 0.7
To make that into a percentage, multiply by 100
Thus, the percentage of students that did not select soccer is 70%.
Hope this helped!

Answers:
Rate of change = -5
Initial value = 25
Step-by-step explanation:
Each time x increases by 2 (eg from x = 1 to x = 3), the value of y drops by 10 (eg from y = 20 to y = 10)
Therefore the slope is...
slope = rise/run = (change in y)/(change in x) = -10/2 = -5
slope = -5
So each time x increases by 1, y will decrease by 5
Flip things around: each time x decreases by 1, y will increase by 5
So the pair (x,y) = (1,20) shown in row 1 of the table leads to (0,25) based on the rule above. Another way to see this is to plug m = -5, x = 1 and y = 20 into y = mx+b and solve for b to get b = 25
