Find the value of y-8 when y = 15.
2 answers:
Answer: y=3
Step-by-step explanation:
the initial statement is
y
∝
1
x
to convert to an equation multiply by k the constant
of variation
⇒
y
=
k
×
1
x
=
k
x
to find k use the given condition
y
=
15
when
x
=
5
y=kx⇒k=y x=15×5=75
equation is

∣22y=75x22∣∣
when x=25 then
y=75 25=3

Answer:
Step-by-step explanation:
Total distance: d = 3 km
Minutes run: x
Distance run = (1 km / 2 minutes) * x = (1/2)x
Distance from the finish line = total distance - ditance run = 3 - (1/2)x =
= - (1/2)x + 3
Answer - (1/2)x + 3
Find A first by using formula: (a+b)/2= midpoint
so: A = [(-17)+(55)]/2
= 36
Now find B using midpoint formula:
B: (a+b)/2
=36+0/2
=18
