Solve the system by substitution y=x^2-2x+1 y=2x+1

 The required solution of the given system is

Step-by-step explanation:  We are given to solve the following system of equations by the method of substitution :

Substituting the value of y from equation (ii) in equation (i), we get

When x = 0, then from equation (ii), we get

When x = 4, then from equation (ii), we get

Thus, the required solution of the given system is

it would open into a square depending on the type of envelope i’m not sure about the second part

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
