I line that is perpendicular is a line with reversed slopes like 2/1 is perpendicular to -1/2. So find the slope by getting the y by itself and reverse it. Remember to switch the signs too! P.S. if you don't know how to get the y by itself just take and subtract 3x from -5y and -4 then divide by 5. Hope I helped!
$38x0.15= 5.70
$38.00+$5.70=$43.70 is the total bill
Answer:
Is there answer choices?
Step-by-step explanation:
Not very clear, could be any number of things. If there are words to choose from i can help you.
Vertex form for a parabola with vertex (p,q) is
We have (p,q)=(-4,5) and another point (-3,2) so we can solve for <em>a:</em>
Putting it together,
Answer: 
We could multiply that out if we like but I won't bother.
The original side length was 12m therefore the perimeter was 36m. 12/4 is 3 so the perimeter is now 9, and the difference between them is 27.
