What is the result of substituting for y in the bottom equation? y = x – 3 y = x2 + 2x – 4 a. (x – 3) = x2 b. y = (x – 3)2 + 2(x – 3) – 4 c. x – 3 = x2 + 2x – 4 d. y = x2 + 2x – 4 – (x – 3)

We have been given two equations.

and

When we will substitute y in one of these equation we will get

Now let us find which of the given options are equivalent to our equation.

A) This is not equivalent to our answer.   is missing.

B) In this equation y's value has been substituted in place of x which will make the equation wrong. When we will substitute value of  we will get which is not true.

C) is equivalent to our equation.

D) In this equation is being subtracted from . When we will simlify this equation we will get

This is not true and we were asked only to substitute y in our given equation.

Therefore option C is correct.

C.

Step-by-step explanation:

We are given that two equations

....(1)

....(2)

We have  to find the result of substituting for y in given equations.

To find the result of substituting for y we will substitute the value of y in any one equation .

Substitute the value of y in equation (2)

Then, we get

Hence, this is the result of substituting for y in given equation.

Hence, option C is true.

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
