What are 3 methods to solve a systems of equations problem?
Graphing, Substitution, and Elimination!
Describe what makes a number irrational?
An irrational number is a non-repeating and non-terminating decimal. It can't be written as a fraction, and it is all NON perfect squares.
What are the slope and y intercept in this equation? y=2x-4
Slope is 2
y intercept is -4
What is the definition of a function?
A relationships of numbers where each input is related to exactly one output.
If a figure is in the first quadrant and you rotate it 180 degrees clockwise, what quadrant will it be in now?
The third quadrant!
Solve for x
5(x+2)=3x-8
x = -9
Give an example of a rational number.
Answers will vary, but can include a perfect square, any number that can be written as a fraction, a repeating decimal, a terminating decimal, or any counting numbers and their opposites.
What is the rate of change in the graph?
The rate of change is 4/2 or $2 per ticket
(1,5) (2,7) (3,10) (4,2) ( , )
Answers will vary, but any answer with 1, 2, 3, or 4 as the x value.
Find the volume. Use 3.14 for Pi
3.14(25)2(10)
78,500 inches
Solve for x
2(10 - 2x) = 4(2x + 2)
x = 1
