Which equation is a linear equation?
a)
2/3xy − 3/4y = 0
b)
3a + 5b = 3
c)
4m2 = 6
d)
x2+y2 = 0

  b)  3a + 5b = 3

Step-by-step explanation:

An equation is linear if each term is a constant or is of degree 1, that is, it has only one variable to the first power.

__

a) the term containing xy is 2nd-degree

b) all non-constant terms are 1st-degree -- this is a linear equation

c) m^2 is a 2nd-degree term

d) x^2 and y^2 are both 2nd-degree terms

For this case we have that by definition, a linear equation is of the form:

Thus, we have the following options:

Option A:

It is not a linear equation !!

Option B:

It is a linear equation!

Option C:

It is a quadratic equation, the exponent of the variable is 2.

Option D:

It is a quadratic equation, the exponents are quadratic!

Option B

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

probably .5

i can on others if necessary.
