Step-by-step explanation:
8x+3y=18
subject y according y=mx+c
y=8/3x-6
(-9,-13)
substitute -9 to y=8/3x-6
-13=8/3×(-9)+c
11=c
y=8/3x+11
When you distribute, its basically when you give out things, as in, distribution.
Hope this helps!!
If you need any help,, just let me know :) :) :) ) ) :) :) ) :)
the answer is 122 because you times 43 x 4 - 50 =122
4x(3x + 8) - 7y(5x - 1) =
12x^2 + 32x - 35xy + 7y
Answer:
xy/180 km
Step-by-step explanation:
Mathematically, we have it that;
Speed = distance/ time
If he cycles x km in 3 hours
We know that ; 60 minutes = 1 hr
3 hours = 3 * 60 = 180 minutes
So the speed in km per minutes will be;
x km/180 minutes = x/180 km/minute
Recall,
Distance = speed * time
= x/180 * y = xy/180 km
