7. Which two equations are equivalent?
sineoko [7]

Answer:

C. y=(x-3)^2 and y=x^2-6x+9

Step-by-step explanation:

before answering the problem let us remind the formula for square of sum and differences

(a+b)^2=a^2+2 \times a \times b + b^2

(a-b)^2=a^2-2 \times a \times b + b^2

We are going to use the above two formulas to solve each part and come to an answer

A. y = (x + 3)^2

(x + 3)^2=x^2+2 \times x \times 3 + 3^2

(x + 3)^2=x^2+6x+9

Hence this option is not correct pair

B. y = (x-5)^2

(x - 5)^2=x^2-2 \times x \times 5 + 5^2

(x -5)^2=x^2-10x+25

Hence this option is also not correct pair

C. y = (x -3)^2

(x - 3)^2=x^2-2 \times x \times 3 + 3^2

(x -3)^2=x^2-6x+9

Hence this option is correct as it have equivalent pair

D. y = (x + 5)^2

(x + 5)^2=x^2+2 \times x \times 5 + 5^2

(x + 5)^2=x^2+10x+25

Hence this option is also not correct pair
