Question

How many solutions will this system of equations have?

y = 3.5x − 3.5
y = −3.5x + 3.5

No solution
Infinite solutions
One solution
Two solutions

Answer 1

Hi there :)
We are given 2 equations
y = 3.5x − 3.5 <---equation 1
y = −3.5x + 3.5 <----equation 2
Both tell use what y equals to just take equation 1 and plug it into equation 2
3.5x-3.5=-3.5+3.5
Solve for x

Answer 2

For both equations, solve for x?

Answer 3

Y =3.5x - 3.5

+ 3.5

y + 3.5 = 3.5x

3.5 3.5

y+3.5
______ = x
3.5

Answer 4

Solve for only the equation i gave
\[\huge~\rm~3.5x-3.5=-3.5x+3.5\]

Answer 5

3.5x-3.5=-3.5+3.5

3.5+3.5 = 0

3.5x - 3.5 = 0

X Must = 1

Answer 6

-3.5+3.5 = 0 *

Answer 7

:D

Answer 8

YES :D
Ok now sub in x value to e1
y=3.5x−3.5:
y=3.5x−3.5
y=(3.5)(1)−3.5
y=?

Answer 9

0
