Ihave this study guide for a test, and my math teacher gives us the answers to the study guide so that we could check our work. for question 1, the question was "identify all the real square roots of -√49/25. i am pretty sure that it is -7/5 but the answer key says that there are no real square roots, which makes no sense to me. am i correct or is my teacher?

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.

d

step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.
