Answer:
Step-by-step explanation:
place a point at (0,0)- the starting point
next point at (2,1) - in 2 minutes she is 1 block away
Next point (4,2)- in 4 minutes she will be 2 blocks away
Connect those 3 points
then place a point at (9, 2)- 5 minutes later she was still at the store
Connect points
Point at (11,1) and (12,0) and connect
First you would knock out the zeros
20,400-> 20,40 10-> 1
Then divide like normal
2040 divided by 1 equals 2,040
Q-2r=4, therefore: q=4+2r.
Plug the value of q into q+r=37, so you get:
4+2r+r=37
3r=37-4=33
3r=33
Therefore: r=11.
q-2r=4, but r=11, so:
q-2(11)=4
q-22=4
Therefore q=26.
Check if the answer is correct using second equation:
q=4+2r=4+2(11)=4+22=26.
So: q=26 and r=11.
Answer:
Step-by-step explanation:
(-8,1) is ⊥ to y=2x-17
from y=mx+c
comparing with
y=2x-17
m₁₌2
for perpendicularity m₂=-1/m₁
m₂₌-1/2
equation of a line with one point y-y₁/x-x₁=m
(-8,1) are x₁ and y₁ respectively
y-1/x-(-8)=-1/2
y-1/x+8=-1/2
cross multiply
2(y-1)=-1(x+8)
2y-2=-x-8
2y=-x-8+2
2y=-x-6
divide both side by 2
y=-1/2x-3
