Hi! So I got :
-3 —>20
-2 —>13
-1 —>8
0 —>5
1 —>4
2 —>5
3 —>8
I’m sorry if any of these are wrong but In order to find the answers I used the “graphing quadratics” one (don’t know the name so sorry) but yeah first I found the axis of symmetry which was 1 and from there I built a chart and substituted. Again, I didn’t see some answer choices above in the image so sorry if there wrong, but yeah I hope this helped! (This is from algebra 1 by the way)
Answer:
The number is 3.
Step-by-step explanation:
5x3=15+12=27
9x3=27
Hope this helps
Answer: 2((x+y)-21)
Calculation/Explanation:
Twice the sum of x and y decreased by 21 means that you must add x and y first before decreasing by 21. The last step is to double the whole equation that we just performed.
Answer:
x^2+9x−1/10
hopefully this helps, it's just writing it backwards
