Answer: the correct is answer is: c
Step-by-step explanation:
The answer is C, 1,2 and 7,14. I know this because 1/2 is the same at 7/14. 7 is exactly half of 14, so if I divide 7/14 by 7 I get 1/2 which is our other set. Therefore, since we know the ratio is equivalent, it is proportional.
Answer:
-5<x<5
both of the < need lines under them
x^2 + x^2 = 128 Normally you don't do this but rewrite the question
1x^2 + 1x^2 = 128
You actually do use 1 + 1 = 2 First time I've ever done that.
2x^2 = 128 Divide by 2
2x^2/2 = 128 / 2
x^2 = 64 Take the square root of both sides
sqrt(x^2)= sqrt(64)
x = 8
because it's value will always be same
