t(1) = 1 = 2(1)-9 / 1 - a
1 - a = 2 - 9 = -7
a = 1 + 7
a = 8 answer
Answer:
yes
Step-by-step explanation:
the line does not overlap
Answer:
find gradient/slope
-8-(-5) / -2-(-1) = -3/-1
= 3
y=3x+c
perpendicular line formula
m1(m2)= -1
(sub in the gradient before)
3(m2)= -1
m2= -1/3 ( perpendicular line gradient)
y=-1/3x+c
(sub in the coordinate)
-5=-1/3(-3/2)+c
-5=1/2+c
-11/2=c (y intercept)
answer: y= -1/3x - 11/2
Answer:
3.125 kilometers
Step-by-step explanation:
6km is 3/4 of her morning speed so 6/(3/4)=6×4/3=8km. Total distance=6+8=14km.
