Answer:
y = -x + 1
Step-by-step explanation:
eqn of line: y=mx+c
perpendicular, m1 x m2 = -1
m × 1 = -1
m = -1
y=-x+c
sub x=-5, y=6
6 = -(-5) +c
6 = 5 + c
c = 1
y = -x + 1
Answer:
Each friend donates $10.
Step-by-step explanation:
If they keep 5% of all donations, 5% of $10 is $0.50 and you lose out on $2.50. With 5 friends, this equates to $10 per person.
15/4 - 6/5 , 300/20 -24/20, 276/20, 69/5
we know that
For a spherical planet of radius r, the volume V and the surface area SA is equal to
The
ratio of these two quantities may be written as
we know
therefore
the answer is
