Answer:
If I had to take an educated guess I'd say 126° but I'm not 100% sure.
Answer:
The distance is 
or 
.
Step-by-step explanation:
Slope of parallel: 2
Slope of perpendicular: -1/2
Pick a point for y =2x + 7. For example (0,7)
Use the perpendicular slope to get to the other line to find the other point of y=2x-3. Look at the screenshot...I got (4,5).
Distance formula 
Insert (0,7) and (4,5)
= 
Answer:
rational
Step-by-step explanation:
Answer:
approx 15%
Step-by-step explanation:
Allison puts $250 down and following that she makes 12 monthly payments of $124.49. The sum of her payments (total cost) is thus $250 + (124.49/month)(12 months) = $1743.88
The total interest she pays is $1743.88 - ($124.49/month)(12 months), or
$250
We use the simple interest formula: i = prt, where t is the number of years, and r is the interest rate as a decimal fraction:
$250 = $1599.99*r*1.
$250
Solving this for r by division, we get r = --------------- = 0.1463, or approx 15%
$1599.99
A percentage is a comparison to 100, so
250% = 250/100 = 25/10 = 5/2
5/2 = 2 1/2 or 2.5
