Answer:
y = -13x + 55
Step-by-step explanation:
perpendicular formula : m1 × m2 = -1
y = -13x + 4
now we take the grafient of the equation which is 13 :
m × 13 = -1
m = -13
so now we hv a new gradient then we can find the equation use the formula y = mx + c :
m = -13 point = ( 4 , 3 )
sub them into the formula,
3 = -13 (4) + c
3 = -52 + c
3 + 52 = c
55 = c
c = 55
now we rewrite again the c and the m to become a complete equation : y = -13x + 55
sides of right angle triangle follows Pythagoras theorem
a^2 + b^2 = c^2
where a, b and c are sides of triangle
if you check, option 3 follow this. so answer is option 3
The amount of water decreases
pints in 12 weeks.
Solution:
The amount of water decreases in 7 weeks =
pints
The amount of water decreases each week is same.
Let us first change the mixed fraction into improper fraction.
pints =
pints
The amount of water decreases in 1 week



So, the amount of water decreases in 1 week is
pints.
The amount of water decreases in 12 week



pints
Hence the amount of water decreases
pints in 12 weeks.
