Hello,
2/10,-6/100,18/1000,-54/10000,162/100000;...
a(n+1)/a(n)=-3/10
a(0)=2/10*1
a(n)=2/10* (-3/10)^(n-1)
Answer B
Answer:
70
Step-by-step explanation:
You do 14*5 because she bikes 7 miles to school and 7 miles back, then a school week is 5 days
3 hours is the correct answer
Answer:
a) y=3x-11
b) y=-1/3x-1
Step-by-step explanation:
First find the slope of the line
rise/run
rise is 3
run is 1
so slope is 3
since this line is parallel to "a", the slope of "a" will also be 3
the equation of a will be
y-y1=3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)
y-(-2)=3(x-3)
y+2=3x-9
y=3x-9-2
y=3x-11
since this line is perpendicular to "b", the slope of "b" will also be reciprocal negative , -1/3
y-y1=-1/3(x-x1) -- where x1 and y1 will be the points it passes through (3,-2)
y-(-2)=-1/3(x-3)
y+2=-1/3x+1
y=-1/3x+1-2
y=-1/3x-1
