Simplify(5p^2-3)+ (2p^2-3p^3)

Answers

Answer 1
Answer: If you would like to simplify (5 * p^2 - 3) + (2 * p^2 - 3 * p^3), you can calculate this using the following steps:

(5 * p^2 - 3) + (2 * p^2 - 3 * p^3) = 5 * p^2 - 3 + 2 * p^2 - 3 * p^3 = - 3 * p^3 + 7 * p^2 - 3

The correct result would be - 3 * p^3 + 7 * p^2 - 3.
Answer 2
Answer: (5 x^(2) -3)+(2 x^(2) -3 x^(3))

Trevor drew lines of best fit for two scatter plots, as shown. Which statement describes the placement of the lines Trevor drew?

Answers

Answer:

A)Only Line A is well placed line of best fit

Step-by-step explanation:

Best fit line :A line through a scatter plot of data points that best expresses the relationship between those points is called best fit line

The least-squares method provides the closest relationship between the dependent and independent variables by minimizing the distance between the residuals and the line of best fit

By considering both the given graphs

We can see that Line A gives the minimum distance between residuals and line of best fit whereas Line B does not give the minimum distance between residuals and line of best fit

So,Option A is true

A)Only Line A is well placed line of best fit

Answer: a) only line A is a well placed line of best fit

For each hour he babysits, Anderson earns $1 more than half of Carey’s hourly rate. Anderson earns $6 per hour. Which equation can be used to solve for Carey’s hourly rate, c?

Answers

Answer:

The equation is 1/2c + 1 = 6

The answer to this equation is 10.

Step-by-step explanation:

Anderson earns $1 more, so you would put '+1' in the equation. Since it says 'half of Carey's hourly rate', you would put 1/2c in the equation. $6 is the total, so that would go on the other side of the equation, thus creating the final equation 1/2c + 1 =6.

Carey earns c hourly
Anderson earns $6 hourly which is also 1+ c/2
So, 6=1+c/2
      12=2+c
c=$10
Carey earns $10 hourly
