Answer:
42 sea otters per mi2
Step-by-step explanation:
Let X be chickens
Let Y be pigs,
then x+y=13
the animals have 2x+4y legs,
so 2x+4y=40
The system of the equations
[X+y=13
[2x+4y=40
Divide the second equation by 2
[x+y=13
[x+2y=20
subtract the first equation from the second one
y=20-13
y-7 pigs
substitute y=7 into the first equation
x+7=13
x=13-7
x=6 chickens
The given term is:
Since here, the numerator i.e.

cannot be factorized.
SO, the only excluded value is found on the basis of the denominator. The denominator should not be equal to 0, otherwise, the fraction will turn out to be zero.
SO, if y

-4, then denominator will not be zero.
Therefore, the excluded value is -4
Answer:
y-3 = 2x
2x-y+3=0 we have
slope
m =- coefficient of x/coefficient of y=-2/-3=2/3 is a slope..
Answer:“A variable is a quantity that may change within the context of a mathematical problem or experiment.” Examples of variables are x, e, and q. In the expression, 5 + X =8, X is the variable.
