Answer:
1) X = 10 Therefore, 10 + 2 + 10 = 22.
2) B = 2 Therefore, 15 = 8(2) - 5 + 2(2)
3) B = -0.9 Therefore, -10 + 4(3(-0.9) + 10) = 19.
Answer:
15
Step-by-step explanation:
Substitute a and b then
Follow PEMDAS
Hope this helps! :)
You just need to try with all of the pair f.ex
0,-2 -> put 0 in the x-> y=8*0-2=-2 so ok it is q possible pair of the function..
You try every pair till you find set where all the pairs fit
So set 1
1 and 6: 8*1-2=6 ok
2 and 14 : 8*2-2=14 ok
Hope I could help
hint; the sum of all angles in a triangle is 180° !
^so all together it’s gonna be 180 !
hope this helped !
i’m pretty sure the value of it (x) is 12 but am not sure
