Georges asked five of his friends how long they studied for the last math test and what grade they received. He found a linear r

egression equation for the data to be y = 9.6x + 65.8. What does the 9.6 mean in the context of this equation?

Dan is 8 years older than Fiona. Gavyn is 9 years younger than Fiona. If the total of their ages is 56, how old is the eldest of

r-ruslan [8.4K]

Answer:

27

Step-by-step explanation:

If Fiona's age is x, Dan and Gavyn's ages respectively are x + 8 and x - 9. We can write:

x + x + 8 + x - 9 = 56

3x - 1 = 56

3x = 57

x = 19

The eldest is Dan (because x + 8 > x and x + 8 > x - 9). His age is x + 8 = 19 + 8 = 27.

It would be estimated about 2,100 trouts I would say, since 7,500 divided by 50 is 150 so 150 x 14 = 2,100 trouts :)

The function f(x) = x] is graphed over the interval [-6, 3]. Which translation of the graph has the domain (-3, 6]? 0 A. g(x) =

bezimeni [28]

An interval graph in graphical theory is indeed an undirected graph formed by an interval set just on true line, with a top for every interval as well as an edge between vertex v to intersections. Graph intervals and these graphs are chordal graphs and graphs that are perfect, and the further discussion can be defined as follows:

Given:

$\bold{function\ f(x) = |x|}$

$\bold{Interval \ \[-6, 3\]}$

To find:

Domain=?

Solution:

The $\bold{function\ f(x) = |x|}$ is a graphic over the $[-6,3]$ interval.

A<em><u> graph of the domain</u></em> $[-3,6 ]$ is indicated mostly by the <em><u>transformation </u></em>that <em><u>horizontal shifts</u></em> to combat $(h(x)=f(x-3))$ .

$\to \bold{h(x) =f(x-3)}$

=|x-3|

Therefore, the final answer is "Option (D)".
