Which of the following choices is the x intercept of the equation 2y-x=-6

Rashid [163]

Answer:

$x = 6$

Step-by-step explanation:

Given

$2y-x=-6$

Required

Determine the x intercept

To get the value of x intercept; we simply substitute 0 for y;

i.e. y = 0

$2y-x=-6$ becomes

$2(0)-x=-6$

$0-x=-6$

$-x=-6$

Multiply both sides by -1

$-1 * -x=-6 * -1$

$x=-6 * -1$

$x = 6$

Hence, the x intercept is 6

The answer is C it’s vertex is at (2,4) because a quadratic formula is suppose to look like y= a ( x - h )^2 + k and the vertex is (h,k) when you look back at Your question h=-2 and but Bc of the formula then it’ll be h=2 and then k=4 and that’s how you get the vertex from a quadratic formula. Hope this helps :)

professor190 [17]

Well, from 2008 to 2010 is just 2 years, so let's say the initial amount is the 19300 from 2008, how many will it be in 2010?

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\to &19300\\
r=rate\to 20\%\to \frac{20}{100}\to &0.20\\
t=\textit{elapsed time}\to &2\\
\end{cases}
\\\\\\
A=19300(1+0.2)^2$
