Find equation where line passes through (7,8) and perpendicular to line y=8
forsale [732]
Since in y=8, the slope is 0 (because there is no x) and b is 8 in y=mx+b, we know that the perpendicular line is x=(something) because the perpendicular lines of y=<number> are x=<number> due to that y=<number> equations are strictly horizontal while x=<number> equations are strictly vertical. Since we know that x=<number> has to pass through (7, 8), x =7

What is 469.82 plus 8.5 sales tax
alekssr [168]
Hey!


The first step to solving this problem would be to multiply 469.82 by 0.085.

<em>New Equation :</em>
469.82 × 0.085 = ?

<em>Solution {New Equation Solved} :</em>
469.82 × 0.085 = 39.9347

Ignore the forty seven at the end of the solution. You're only going to need 39.93. Now we'll add 469.82 and 39.93. This is the sales tax plus the regular price. Which will then bring us to our total.

<em>New Equation :</em>
469.82 + 39.93 = ?

<em>Solution {New Equation Solved} :</em>
469.82 + 39.93 = 509.75

<em>So, 469.82 plus 8.5 sales tax is</em>  509.75.

Hope this helps!
