Step-by-step explanation:
(x10,y-2), reflection over y=1
(5, 12) e (-10, -3)
x.......y...1
5.....12..1
-10..-3..1
12x -10y -15 + 120 -5y + 3x = 0
12x + 3x - 10y - 5y - 15 + 120 = 0
15x - 15y + 105 = 0 :(5)
3x - 5y + 21 = 0
m = -a/b
m = -3/-5
m(5) = 3/5
y-yo = m(x-xo)
y-14 = 3/5*(x-7)
y-14 = 3x/5 - 7/5
3x/5 - y + 14 - 7/5 = 0
3x/5 - 5y/5 + 70/5 - 7/5 = 0
3x - 5y + 70 - 7 =0
3x - 5y + 63 = 0
m(s) = -3/-5 = 3/5
m(r) = m(s) --> são paralelas
Answer:
(3, 3)
Step-by-step explanation:
The solution of such a system is the ordered pair that is a solution to both equations. To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect.

EXPLANATION: Pi is an infinite decimal number with no end, which means that after the decimal point, the digits go on forever.
Answer:
Step-by-step explanation:
speed = s = 3.5 miles / hour
d = 6 miles
t = ?
============
t = d / s
t = 6 / 3.5
t = 1.714 hours
t = 1 5/7 hours
You could figure this out in minutes for 5/7 but it will not make the time any clearer. You will still wind up with a fraction.
