Answer:
Step-by-step explanation:
The following code is written in Python. It is a function that takes in the number of miles as an argument and returns the number of laps that those miles represents.
def miles_to_laps(miles):
laps = miles / 0.25
return laps
Answer:
625 millilitres
Step-by-step explanation:
1 litre = 1000 millilitres
Left -> 1000 millilitres - 375 millilitres = 625 millilitres
Y = 2/x
x must not have the value of 0 because x is used as a denominator.
A denominator must not have a value of 0 because the overall value of the fraction is undefined.
x may be any positive or negative integer.
x = 1
y = 2/1 = 2 ⇒ (1,2)
x = 2
y = 2/2 = 1 ⇒ (2,1)
x = 3
y = 2/3 = 0.67 ⇒ (3, 2/3)
x = -1
y = 2/-1 = -2 ⇒ (-1,-2)
x = -2
y = 2/-2 = -1 ⇒ (-2, -1)
x = -3
y = 2/-3 or -0.67 ⇒ (-3, -2/3)
You can solve this by substitution:
x + y = -6
y = -6-x
Substitute for y in xy = -7:-
x(-6 - x) = -7
-x^2 - 6x = -7
x^2 + 6x - 7 = 0
(x + 7)(x - 1) = 0
so x = -7, 1
To find the values of y plug these va;ues of x into the equation x + y = -6:-
when x = -7, y = -6 + 7 = 1
when x = 1, y = -6 - 1 = -7
so answer is x = -7 and y = 1
and x = 1 and y = -7
2y=4x +13
Y=2x +6.5
Answer y=2x + 6.5
