I hope this is good enough:
Use the substitution method
(9,90) y= 10x
90= 10(9)
90= 90
Answer is yes
D because 5 times 2 is 10 and - cuts off - so -3 times -3 would be 9 so 10+9 is 19 :)
Sum sum sum sum sum sums calculator use google to find sum times 9$
R^4-2(r-14)>0
r^4-2r+28>0
r^4-2r+28=0
There is no real solution but there is all real numbers
