Answer:
rise over run
Step-by-step explanation:
In this case it is undefined
Perpendicular lines have slopes that multiply to -1
y=mx+b
slope=m
y=5x+3
5=slope
5 times what=-1
divide both sides by 5
what=-1/5
the equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
given
m=-1/5
point=(-1,-1)
y-(-1)=-1/5(x-(-1))
y+1=-1/5(x+1)
y+1=-1/5x-1/5
y=-1/5x-6/5
1/5x+y=-6/5
x+5y=-6
the euation is
y+1=-1/5(x+1) or
y=-1/5x-6/5 or
x+5y=-6 (all same equation but different forms)
Since Seema runs 5 more miles than Padma, we could find how long Padma runs by subtracting 5 miles from the amount of miles that Seema runs. If P is equal to the distance that Padma runs, our equation is:
P = 17-5 = 12 miles.
Answer:
9. the measure of DEF is 103°
10. the measure of DEG is 77°
11. 90°
Step-by-step explanation:
it's pretty simple, just take into consideration that the final measure of all the angles of a triangle must be 180°
