Alexa and Samantha work at a furniture store. Alexa is paid $250 per week plus 9.5% of her total sales in dollars, xx, which can

8_murik_8 [283]

Answer:

As per the statement:

Here, x represents the total sales in dollars

Total weekly pay of Alexa in dollar is represented by:

$g(x) = 250+0.095x$

and

Total weekly pay of Samantha in dollar is represented by:

$f(x) = 413+0.085x$

We have to find the value of x, in dollars that will make their weekly pay the same.

⇒ $g(x)=f(x)$

Substitute the values we have;

$250+0.095x = 413+0.085x$

Subtract 250 from both sides we get;

$0.095x =163+0.085x$

Subtract 0.085 x from both sides we get;

$0.01x =163$

Divide both sides by 0.01 we have;

$x = \frac{163}{0.01}$

Simplify:

x = $16300

Therefore, $16300 that will make their weekly pay the same

What is the equation of a parabola y(x) that has a vertex at point (− 1/3 , 0.3) and passes through point (− 2/15 , − 1/2 ).

Savatey [412]

bearing in mind that 0.3 = 3/10

$\bf ~\hfill \textit{parabola vertex form}~\hfill \\\\ \begin{array}{llll} y=a(x- h)^2+ k\qquad \leftarrow \textit{we'll use this one}\\\\ x=a(y- k)^2+ h \end{array} \qquad\qquad vertex~~(\stackrel{-\frac{1}{3}}{ h},\stackrel{\frac{3}{10}}{ k}) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ y=a\left[ x-\left( -\cfrac{1}{3} \right) \right]^2+\cfrac{3}{10}\implies y=a\left( x+\cfrac{1}{3} \right)^2+\cfrac{3}{10}$

$\bf \textit{we also know a point } \begin{cases} x=-\frac{2}{15}\\\\ y=-\frac{1}{2} \end{cases}\implies -\cfrac{1}{2}=a\left( -\cfrac{2}{15}+\cfrac{1}{3} \right)^2+\cfrac{3}{10} \\\\\\ -\cfrac{1}{2}-\cfrac{3}{10}=a\left( \cfrac{1}{5} \right)^2\implies -\cfrac{4}{5}=a\left(\cfrac{1}{25} \right)\implies -\cfrac{4}{5}=\cfrac{a}{25}\implies \cfrac{-4\cdot 25}{5}=a \\\\\\ -4\cdot 5=a\implies \boxed{-20=a} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill y=-20\left( x+\cfrac{1}{3} \right)^2+\cfrac{3}{10}~\hfill$
