Answer:
The number lines are shown below.
Step-by-step explanation:
In the given problem the sign of inequality is missing.
We know, that there are 4 signs of inequality ">", "<", "≥" and "≤".
The possible inequalityes are

In , all points on the left side of 23 are included in the solution set.
In , 23 and all points on the right side of 23 are included in the solution set.
In , 23 all points on the left side of 23 are included in the solution set.
Answer:
1 1/2x
Step-by-step explanation:
90 minutes is 1 and 1/2 hours so I put that with the x on the end so when you get the number times it by that
33/9=11/3 or 3.666666667
hope this helps!

Answer:
<em>A.</em><em> There were 400 larvae at 0 degree Celsius.</em>
Step-by-step explanation:
Here,
x = the temperature of water in °C
y = the number of insect larvae in the water
The graph is a graph of quadratic function as it is a parabola and it opens downward, so it has a negative leading coefficient i.e coefficient of x² is negative.
At y intercept, the line or curve passes through y axis. At y intercept the value of x is zero, because on y axis the value of x is 0.
As the y intercept in this case is (0, 400), so at y intercept value of x is 0 and y is 400.
Therefore, at y intercept or at 0°C there were 400 larvae.
