4 because 4 is a natural number and and whole number and real number and is also a internet
Answer:
Step-by-step explanation:
x is greater than minus 3. You have everything right but the graph. The arrowhead goes the other way. Around -3 is as small as x gets.
0====0====0====0====0
-3 -2 -1 O 1

Answer:
The answer is the first one.
0 = 3x2 + 2x – 2
Step-by-step explanation:
The leading coefficient is the number before the x^2
The constant term is the number that never changes so the number with no x after it.
Answer:
30 students would have to go for the cost to be the same.
Step-by-step explanation:
Bus A: $40 + ($4 * 30) = $160
Bus B: $100 + ($2 * 30) = $160
We can solve this by substitution. Let's make the second equation equal y by adding y to both sides. The equation would look like:
x-5=y
Let's plug that equation in for y in the first equation.
2x+x-5-10=0
Let's add like terms.
2x+x-15=0
Let's add 15 to both sides.
2x+x=15
3x=15
Now divide.
15÷3=5=x
Now, x equals 5, so that means y equals 0. Let's check in both equations.
2(5)+0-10=0
10+0-10=0
0=0
5-0-5=0
0=0
So, the solution of the system shown is (5,0). I also included a graph so you could see where they intercept. The solution, when put in the graph, is the x intercept.
