Answer:
B
Step-by-step explanation:
1. In order to determine the inequality, you must first solve the solution set to determine what x is less than.
So you would do this:
1 + 2x < 9 Subtract 1
2x < 8 Divide by 2
x < 4
2. Next, you need to understand the difference between an open circle and a closed circle shown on the solution sets.
An open circle is equal to the following inequalities:
<, >
A Closed circle represents inequalities in situations such as:
greater than or equal to, or less than or equal to
3. Because the inequality above represents only less than or greater than the inequality sets should have an open circle being used.
Since x is less than 4 it should be moving to the left of the line inequality set.
Answer: Stratified Random Sampling
Step-by-step explanation: Got it right
Answer:
2, quadratic, 1
Step-by-step explanation:
Degree is the highest power which is 2 then the lead coefficient is the constant multiplying the highest power so for x^2 it is 1 and the type of equation is what is it, linear, quadratic, cubic, etc. For this it is quadratic because x^2 means its a parabola.
If it is hexagon, 6 sides
1 side = 3x+5
6 sides = 6(3x+5)
perimeter
18x + 30
Answer:
y=mx+b
also if you ask me how I got that is because you need to listen carefully to the math teacher word so you can remember the answer
