Answer:

a) not one to one function; horizontal line intersects the graph of the function more than once.

b) yes it's a one to one function; the graph passes the horizontal line test

c) not one to one function; the graph doesn't pass the horizontal line test

d) yes it's a one to one function; the horizontal line doesn't intersect the function more than once

Can someone help me? Forgot how to do this, it’s been awhile

Answer: y=5

Step-by-step explanation:

Similar basically means it's the same shape but bigger. Condiering how 16-9=7 which means each side is 7 bigger than the original shape. You subtract 7 from 12(side y) to get 5

How do I subtract 4m^2 + 2mn + 8n^2 from 2m^2 + 6mn + 2n^2 ?

SVETLANKA909090 [29]

$-2m^2+4mn-6n^2$

1) Let's write out both expressions subtracting 4m²+2mn+8n² from 2m²+6mn+2n²

$\begin{gathered} 2m^{2}+6mn+2n^{2}-(4m^{2}+2mn+8n^2)_{} \\ 2m^2+6mn+2n^2-4m^2-2mn-8n^2 \\ -2m^2+4mn-6n^2 \end{gathered}$

2) Note that when we subtract 4m^2 + 2mn + 8n^2 from 2m^2 + 6mn + 2n^2 we need to swap the sign by placing -1 outside the parentheses and then combine like terms adding those terms algebraically.
