<u>Answer</u>

The slope of the equation.


<u>Explanation</u>

The general equation of line is y = mx + c, where (x,y) is a point on the line, m is the slope and c is the y-intercept.

When the line is in the equation above, we can explain the meaning of each term.

After recording the  data plotting the line, Ted came up with the equation;

y = 300 + 0.45x.

Writing this in the form of y = mx + c we have,

y = 0.45x + 300.

m = 0.45 ⇒ This is the slope of the equation.

Choose the function that shows the correct transformation of the quadratic function shifted two units to the right one unit up.
Gnom [1K]

Answer:

  ƒ(x) = (x - 2)^2 + 1

Step-by-step explanation:

To make f(x) be a translation of the graph of g(x) by (h, k), write it as ...

  f(x) = g(x -h) +k

You want to translate g(x) = x^2 by (2, 1), 2 units right and 1 unit up, so the function f(x) is ...

  f(x) = g(x -2) +1

  f(x) = (x -2)^2 +1

The degree of the polynomial p(y) =(y-4)^3-y^3 is<br><br>Plz urgent ​
Scilla [17]

Answer:

The degree of polynomial is 2

Step-by-step explanation:

Given

p(y) = (y -4)^3 - y^3

Required

The degree

When expanded,  p(y) = (y -4)^3 - y^3 is:

p(y) =y^3-12y^2+48y-64-y^3

Collect like terms

p(y) =-12y^2+48y-64-y^3+y^3

p(y) =-12y^2+48y-64

<em>The degree of freedom is 2</em>

Javier had $305in his bank account. His bank charges a fee of $7.50each month that a balance is below $500.
Mama L [17]

Answer:

Javier’s account has $282.5 at the end of the three months.

Step-by-step explanation:

final = initial - 7.5x

initial is the initial amount of money in the account, so 305. x is the number of months that have passed. Since Javier doesn't deposit any more money durning that time, the amount in the bank will always be less than 500 we don't have to consider anything else. We just sub initial with 305 and x ( the number of months) with 3 to get the answer. So,

final = 305 - 7.5 * 3 = 282.5
