Step-by-step explanation:
Answer:
<h3>Part A</h3>
<u>4 CD's cost $30.40, so one CD costs:</u>
- 4p = $30.40
- p = $30.40/4
- p = $7.60
<h3>Part B</h3>
80% of the regular price is $7.60
<u>If the regular price is r, we have:</u>
- 0.8r = $7.60
- r = $7.60/0.8
- r = $9.5
<u>3 CD's at regular price cost:</u>
Since $25 < $28.5, we can't buy 3 more CD's.
<h3>Part C</h3>
Isolate the variable by dividing each side by factors that don't contain the variable.
y = 2 − x
Being multiplied by 5 every time. Answers are a=250 b=1,250 c=6,250
Answer:
one: 9
Two: D
Step-by-step explanation:
One
The symbol used is x≥8 so 8 is included in the function part. That would mean that F(x) = 9
Two
The value you need to use is -4x + 3. That's because -2≤x and the symbol ≤ makes - 2 inclusive.
-4(-2) + 3 = 8 + 3 = 11
3a
The function is decreasing over -4x + 3
It goes from 11 to -29 roughly. That means it's going from a positive to negative number. Definitely decreasing
3b
The function is a constant when x≥8. The value of the function is 9 no matter what x is.
3c
The function is increasing from - 2x to 8 which is going from -9 to 11
