1. y < -x - 5......(-3,-4)
2. 5x - 3y < = 15.....all of ur answers satisfy this inequality
I know this wont help but y=mx+c or +b will need to be used so y will equal to 3x+5 so the equasion is y=3x+5
sorry, thats all i can do
Answer:
99 marbles
Step-by-step explanation:
Let number of marbles with Alex be
Leanne has 1/2 as many marbles as Alex.

Answer:
Mean of boiling times = 26.9 seconds
Step-by-step explanation:
Times ella recorded are given as;
24.5 seconds, 23.2 seconds, 29.8 seconds, and 30.1 seconds.
Now, we want to find the mean of these boiling times.
Formula for mean is;
Mean = sum of terms/number of terms
In this question,
number of terms = 4
Sum of terms = 24.5 + 23.2 + 29.8 + 30.1 = 107.6
Thus,
Mean = 107.6/4
Mean = 26.9 seconds
