Answer:
Step-by-step explanation:
line perpendicular to ax+by=c is
bx-ay=k, where k is a constant.
if it passes through (-1,2) then
b(-1)-a(2)=k
or k=b-2a
so reqd. eq . is bx-ay=b-2a
Answer is 17.647 or if rounded 18
The answer is n=(a-b)-1 because when you subtract a-b, you get almost the number of pages, but as you are counting the page b which has is not torn out, you must subtract 1 to get the correct answer if you plugged in a variable
Answer:
y+5/3x=34/3
Step-by-step explanation:
y=mx+b
3=5m+b
-2=8m+b (system of equations, subtract them)
5=-3m
-5/3=m
3=5m+b
3=5(-5/3)+b
3=-25/3+b
9/3+25/3=b
34/3=b
y=-5/3x+34/3
y+5/3x=34/3
-13 is lower than -10, therefore the question would be -13<-10
