The given expression is :
2xx+3-5(x-2)
We know that, 
Aleena expands 2xx+3-5(x-2) as 2x²+3-5x-10. She is mistaken because the sign before 10 should be +10 instead of -10. Hence, the correct expanded form is 2x²+3-5x+10. Hence, this is the required solution.
Answer:
Correct rate of change is -5; correct initial value is 3.
Step-by-step explanation:
The rate of change is the coefficient of the x term, which here is -5. So Bryan has the rate of change wrong.
The initial value of the function is found by letting x = 0. Here, we get
y = -5(0) + 3, or y = b = 3. The initial value is 3, not -5.
Based on the charge to the artist and the amount the streaming services pay, the following are true:
- -50.
- 5.
- y = 5x - 50
- .
- 10,000 streams.
- 190,010,000 streams
<h3>What model can be derived for the streaming data?</h3>
The y-intercept would be the amount that the artist has before they start making any money. In this case that amount is -$50 because they will owe the distributor.
The slope is the change per unit which is $5.00 here.
The formula is therefore:
y = mx + b
y = Slope × x + b
y = 5 × x + (-50)
y = 5x - 50
The number of streams to pay off the distributor is when the profit is $0:
0 = 5x - 50
50 = 5x
x = 10 units
Number of streams:
= 10 units x 1,000
= 10,000 streams
To make a profit of $950,000, the units are:
950,000 = 5x - 50
5x = 950,000 + 50
x = (950,000 + 50) / 5
= 190,010 units
Number of streams is:
= 190,010 x 1,000
= 190,010,000 streams
