Question

What is the result of substituting for y in the bottom equation? y = x + 3 y = x2 + 2x - 4

Answer 1

Answer:

The correct option is (B).

Step-by-step explanation:

We need to find the result of substituting for y in the bottom equation.

Equation (1) is : $y=x+3$

Equation (2) is : $y=x^2+2x-4$

Put the value of y form equation (1) to equation (2) such that,

$x+3=x^2+2x-4$

It can be seen from the above equation, that option (2) is same as above equation.

Hence, the correct option is (B).
