Answer:

$11.34 Discounted Price Including Tax

Step-by-step explanation:

CD is $12.00

10 percent off of 12 dollars is:

12 x .10 = $1.2

12 - 1.2 = $10.8 WITHOUT TAX!!

5/100 = 0.05

0.05 x 10.8 = .54 (Tax itself)

10.8 (Discounted price) + .54 (Tax) = $11.34 Discounted Price Including Tax

Write the linear equation in slope-intercept form -4x + 2y = 10

ella [17]

You know slope intercept form is y=mx+b so just put in that form by:
Adding 4x to other side
2y=10+4x
Then divide by 2
Y=10/2 +4/2x
Simplify
Y=5+2x
I rearranged so x is first so your answer would be: y=2x+5

The time t required to drive a certain distance varies inversely with the speed r. if it takes 4 hours to drive the distance at

Aleksandr [31]

$\bf \qquad \qquad \textit{inverse proportional variation}
\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------$

$\bf \stackrel{\textit{time \underline{t} required to drive a certain distance varies inversely with the speed \underline{r}}}{t=\cfrac{k}{r}}
\\\\\\
\textit{we also know that }
\begin{cases}
t=4\\
r=35
\end{cases}\implies 4=\cfrac{k}{35}\implies 4(35)=k
\\\\\\
140=k\qquad therefore\qquad \boxed{t=\cfrac{140}{r}}
\\\\\\
\textit{now, when \underline{r} = 45, what is \underline{t}?}\qquad t=\cfrac{140}{45}$
