Asystem of equations has infinitely many solutions. if 2y – 4x = 6 is one of the equations, which could be the other equation?
a. y = 2x + 6
b. y = 4x + 6
c. –y = –2x – 3
d. –y = –4x + 6

Option C -

Step-by-step explanation:

Given : A system of equations has infinitely many solutions. If is one of the equations.

To find : Which could be the other equation?

Solution :

A system of equations has infinitely many solutions when the two lines representing the equations coincide.

i.e. the two equations are the same or a multiple of each other.

We have given the equation,

Taking 2 common from equation,

or

Take negative both side,

The other equation is  

Therefore, option C is correct.

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
