Answer:
c). y + x = 0
Step-by-step explanation:
The locus is a line perpendicular to the line connecting the 2 points and passing through the centre of the line.
The mid-point of the line connecting the given points is:
(a + b + a - b)/2 , (a - b + a + b) / 2
= (a, a)
It's slope = (a + b)- (a - b) / (a - b)- (a + b)
= 2b/ -2b
= -1
So the slope of the line we want is -1/(-1) = 1.
Using the point-slope form of a line:
y - y1 = m(x - x1)
y - a = 1(x - a)
y - a = x - a
x + y = 0
To change it into minutes you want to do unit analysis
105.6 L / h × 1h / 60 minutes
so 105.6L times 1h divided by 60 gives you:
1.76L / minute
Answer:
5>t
Step-by-step explanation:
45 > 12t + 3(t -8) - 6 multiply 3 times t-8
1) 45 > 12t + 3t - 2 - 6 combine alike terms
2) 45 > 15t - 30 isolate the variable by adding 30
3) 75 > 15t divide by 15
4) 5 > t
