How many solutions does y=-2x+4 and 7y=-14x+28 have?

The given equations y = -2x + 4 and 7y = -14x + 28 has infinitely many solutions

Given that two equations are y = -2x + 4 and 7y = -14x + 28

We have to find number of solutions for this set of equations

Let us first solve the given equations

y = -2x + 4   eqn 1

7y = -14x + 28   eqn 2

Substitute eqn 1 into eqn 2

7(-2x + 4) = -14x + 28

-14x + 28 = -14x + 28

0 = 0

Thus means given equations has infinitely many solutions

The two lines may have an infinite number of intersecting points (infinite solutions).

v = 1/3 a^2h

step-by-step explanation:

if the height is 57.7cm and the height of the slant edge is 18.2cm, then the volume is 1/3 a^2h.
