Answer:
b = 12.5
Step-by-step explanation:
2=3.5(-3)+b
2=-10.5+b (you add 10.5 on both sides)
b= 12.5
There are 3 girls .
9 students , 3 boys & 3 girls + another 3 boys because there are 3 more than girls so there are only 3 girls since you can't exceed 9 .
Hello!
The domain of the function are the x-values that make the function true.
Since the graph has open circles and filled in circles, the open circles make the function false (written as <) , and the filled in circles make it true (written as ≤).
From the graph, the x value -3, and 2 are open circles. While the value -0.5 are filled in circles. Also, from the interval (-0.5, 2), there is gap, so it is part of the domain.
Therefore, the domain of the function is: {x | -3 < x ≤ -0.5} ∪ {x | 2 < x < ∞}, which is the third choice.
Hey there!
To solve for the solutions of your inequality, divide both sides of your inequality by -3 in order to isolate the value of x:
-3x≥36
÷-3 ÷-3
x≤12
**Note: in inequalities, if you ever divide or multiply a number that is negative, you must flip the inequality sign. In this case, because you have divided -3 from both sides, you must flip the inequality sign from ≥ to ≤.
Therefore, your solutions to your inequality would be x≤12.
Hope this helps, and have a nice day! :)
