Answer: " y = -10 . "

Step-by-step explanation:

___________________

The question:

Find the value of "y" when "x" equals 17.

Given the equation:

- x + y = -27 ;

___________________

We plug in the given value: "17" ; for "x" ; and solve for "y" :

- 17 + y = -27 ;

_____________________

↔ y + (-17) = -27 ;

Rewrite as:

y − 17 = -27 ; {since: "adding a negative value" is the same

as "subtracting a positive value."}.

_____________________

Now, we add "17" to each side of the equation;

to isolate "y" on one side of the equation; and to solve for "y" :

y − 17 + 17 = -27 + 17 ;

to get:

y = - 10 .

Answer:

y = -10

Step-by-step explanation:

When x = 17, the equation be -17 + y = -27 when you plug in 17 for x

Then, add 17 to both sides to get y = -10

At the beginning of the bake sale merry set aside two pies for herself Kate bought half of the remaining pies for a birthday par

nirvana33 [79]

So.. .at the beginning of the sale, there was a total of "x" pies

now, let's see what happened to those pies
$\bf \begin{array}{lrlll}
&pies\\\\
&\textendash\textendash\textendash\textendash\textendash\textendash&\\

Mary&x-2\\\\
Kate&\cfrac{x-2}{2}\\\\
\textit{pies sold}&10\\\\
\textit{pies leftover}&14
\end{array}$

so, we had "x"
then Mary took 2, she left x - 2
Kate took half of that (x-2)/2
then 10 were sold, and 14 leftover

if we subtract all those figures, and solve for "x",
we should get what "x" was, so $\bf (x-2)-\left( \cfrac{x-2}{2} \right)-10-14=0$

notice, if we subtract what Mary took, and Kate, and the sold and leftover, from the original "x", we would end up with no pies :)

so.. just solve for "x"

At which root does the graph of f(x) = (x – 5)3(x + 2)2 touch the x axis?

LuckyWell [14K]

We have that
f(x) = (x – 5)³(x + 2)²

we know that
the roots can touch or cross the x axis

The way you can tell if the graph is going to cross the x-axis or just touch the x-axis is by looking at the power of the factor.

(x - 5)³ has a power of 3 which is an ODD number. An ODD power means that the graph will cross through the x-axis.

(x + 2)² has a power of 2 which is an EVEN number. An EVEN power means that the graph will touch the x-axis.

therefore

the answer is
the graph of f(x) touch the x axis for the root x=-2
