Answer:
domain: (-∞ , ∞)
range: (-∞, 2]
Step-by-step explanation:
the domain is the set of values of what the x value can be. This function is parabolic and upside down, it can have a range of x values from - infinity to positive infinity. The function is most likely y=-x^2 +2
range is the output (y values) the function can possibly have. the max is 2 and includes 2 so we use bracket for that. The smallest y value can reach towards negative infinity.

Now, let's do the same as we did for the previous one here.

notice again, how did we get 84 for the 4th element's coefficient? well 36 * 7 / 3. and so on. And you can just expand it from there.
Answer:
8
Step-by-step explanation:
Jeremiah bought x toy sets for $20 each and then a video game for $60. Jeremiah spent a total of $220. How may toy sets did he buy?
To find our answer, we can solve the equation:
20x + 60 = 220
-60 -60
20x = 160
/20 /20
x = 8
Jeremiah bought 8 toy sets!
I hope this helps :)
Answer:
14 I think I'm. it completely sure
Answer:
Answer:
44 = 12 + M
Step-by-step explanation:
Start with your final amount that everything else is going to equal
44 =
Then, add the $12 that is already saved to the other side\
44 = 12
But, that equation is not true yet, so we have to add the amount of money that she still needs to save
44 = 12 + M
That equation shows that the money she has saved ($12), plus the amount she still has to save will equal the amount she needs.
