Answer is t_<10
-3t+9_>-21
-3t_>-30
t_<10
**when you divide or multiply both sides by a negative you have to flip the sign**
you can substitute numbers to make sure your answer is correct. For example if u substitute t=9 -27+9_>-21 -18_>-21 which is correct.(but you’ll see it’ll be incorrect if u put t=11)
The top question, is 12’-1
The bottom is 12’2
The exponents are subtracted first which is just basic addition/ subtraction. Good luck!
5 times,
220 - 140 = 80
80 divided by 16 equals 5.
to double check, you can do 5 x 16 to get 80.
Did you copy and paste the question? you will have to fully type it out or insert a link to be able to get a good answer.
The slope of this line is -1 you find this by using the slip formula of y-y over x-x find two points on the line so I used points (-2,2) and (-1,1) plug them into the formula to get the slope of -1 hope this helps:)
