Answer: 5$
Explanation:
1hr = 6$ but 1hr = 60min
Or 60min = 6$
If he walk the dog for 50min:
60/50 = 6/x
X = (6 x 50)/60
X = 300/60
X = 5$
X is the amount he was paid for walking the dog for 50 min.
And 7:30 - 6:40 = 50min
Do you mean what does infinity + infinity equals to? If so, infinity + infinity = infinity.
Answer:
Step-by-step explanation:
y=mx+b
so inset the first point into the equation
-3 for x and 7 for y.
7=m(-3)+b
y=mx+b
1 for x and -1 for y
-1=m(1)+b
now put them together and solve for m and b.
-1=m+b
7=-3m+b
--------------------
-1-b=m
7=-3m+b
inset m into the equation
7=-3(-1-b)+b
7=3+3b+b
4=4b
b=1
--------------
insert b back in for -1=m+b
-1=m+1
m=-2
---------------------------------------
Now insert it back into y=mx+b
y=(-2)x+1
so this line contains those points that were given
Hope this helps :)
