3. how many solutions does the system have? }
sy = x2 + 4x – 2
1 y = 2x+1

Hence two solution of expression

I.e x= 1 , - 3

Step-by-step explanation:

Given as :

y = x² + 4 x - 2

And y = 2 x + 1

Solving these equation

x² + 4 x - 2 = 2 x + 1

or, x² + 4 x - 2  - 2 x -  1 = 0

Or, x² + 2 x - 3 = 0

Or,  x² + 3 x - x - 3 = 0

Or, x ( x + 3 ) -1 ( x + 3 )= 0

Or, ( x + 3 ) ( x - 1 ) = 0

or, x = - 3  And x = 1

Hence two solution of expression Answer

x-150=475   x=625

step-by-step explanation:

if the bike after the sale ($150) is $475 then just simply add 150 to 475.
