G(x)=8(x-3)-7
The number in the parentheses has to be changed to positive 3.
You keep the number (-7) the same sign it already is. The vertex is (3,-7)

Answer:

option (2) is correct.

The vertex is (3 , -7)

Step-by-step explanation:

 Given: the function g(x) = 8x^2-48x+65 written in vertex form isg(x) = 8(x-3)^2-7.

We have to write the vertex form of g(x).

For a given quadratic function f(x)=ax^2+bx+c , we can rewrite it in vertex form  f(x)=a(x-h)^2+k , where (h , k) represents the vertex of the function f(x).

For the given quadratic function g(x) = 8x^2-48x+65 written in vertex form is g(x) = 8(x-3)^2-7.

On comparing , we get

h = 3 and k = -7

Thus, the vertex is (3 , -7)

Thus, option (2) is correct.

Answer:

  b, e

Step-by-step explanation:

a, b) ordinarily, we claim the variable on the vertical axis is a function of the variable on the horizontal axis. By that claim, <em>temperature is a function of time</em>.

If the graph passed the horizontal line test (a horizontal line intersects in one place), then we could also say time is a function of temperature. The graph does not pass that test, so we cannot make that claim.

c) The graph has negative slope between 4:00 and 5:00. Temperature is decreasing in that interval, not increasing.

d) The graph has two intervals in which it is horizontal: 5:00-9:00 and 11:00-12:00. In those intervals it is neither increasing nor decreasing.

e) The graph shows a minimum in the interval 11:00-12:00. <em>The lowest temperature first occurs at 11:00</em>.

Find an equivalent expression for each expression by simplifying. (3x - 5y) + 7y
sertanlavr [38]
This question is quite simple really. They are basically asking you to combine like terms. You have two different figures with the variable y, so you just combine the them. It would then be 3x + 2y. You cannot simplify this equation any further since there is nothing to solve for or anymore like terms to combine.
