Answer:
-12

Explanation:
Because negative numbers are impossible to simplify, we must use imaginary numbers. i=root -1. So, for example to simplify root -9, separate this into root 9 times root -1 which becomes root 9 times i, simplifying to 3i. Repeat this for root -16 to have 3i times 4i. Multiply and get 12i^2. Then, simplify to 12 times -1 because i^2 is root -1 times root -1 making -1. Finally, the answer is -12.
I apologize for this sloppy explanation as I am currently short on time. If you have any questions feel free to ask in the comments and I will try to answer them later!

To find the common ratio, u take ur 2nd term, and divide it by ur 1st term
(-1/6) / (5/12) =
-1/6 * 12/5 =

Each set of ordered pairs represents a function. Write a rule that represents the function.
malfutka [58]
My answer to the question is as follows:

First one looks like you are squaring the number, then multiplying the result by 4, i.e.

<span>y=4<span>x2

</span></span><span>second one is similar, but instead of squaring and multiplying by 4, you are squaring and then dividing by 2
</span>
I hope my answer has come to your help. God bless and have a nice day ahead!

Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2
vladimir2022 [97]

ANSWER


x=-0.62 or x=1.62




EXPLANATION


For -x^2+y=1



We make y the subject to obtain,



y=x^2+1


We can easily graph this function, because we just have to transform the graph of y=x^2 by shifting the intercept up to 1.



As for the straight line, -x+y=2,


We find the intercepts as follows,



When y=0,x=-2.


When x=0,y=2.


We plot the points (-2,0) and


(0,2).



We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be


x=-0.62 or x=1.62


See graph

Solve the system by graphing. It is REQUIRED to check your solution. Show work for this problem on your work page.
Hunter-Best [27]

Answer:

y=x-1

y=-2x-4

although I cant summon a graph for this one, I can give cords

for first graph (-2,-3),(-1,-2),(0,-1), (1,0),(2,1)

For second graph the slope is down 2 over 1, and begins at (0,-4).

(-2,0)(-1,-2),(0,-4),(1,-6),(2,-8)
