Equations/Transformations
When do you have one solution to an equation?
When the variables do not cancel out and you get a final answer.
What is another name for "slope" that you will see on the state test?
Rate of Change
For every input (x value) there is only one output (y value)
What is the Pythagorean Theorem?
a2 + b2 = c2
When it comes to scatter plots, what is another name for relationship that they will ask you?
ASSOCIATION
When do you have no solution to an equation?
When the variables cancel out and the numbers left on both sides of the equal sign DO NOT match.
With parallel lines, acute angles are equal to each other and obtuse angles are equal to each other... But what does an obtuse and acute angle add up to be?
180 degrees
Fill in the blanks:
A linear function and a constant rate is a _________. A nonlinear function and a nonconstant rate is a __________.
Straight line
Curved or not straight line
What is a and b in the Pythagorean Theorem? What is c?
a and b are your legs. c is your hypotenuse.
What are the two line of best fit rules?
1) Must go in the same direction as the points
2) Try to have as many points above the line as below the line (or close to it)
When do you have infinite solutions to an equation?
When the variables cancel out and the numbers left on both sides of the equal sign DO match.
Where is the solution to a system of equations on a graph?
Where the two lines INTERSECT!
If they ask you to write an equation representing a function, it will be in what form?
y = mx + b
What is an integer?
A number with NO decimal.
If they give you a two way table with decimals in the boxes and ask "how many?" what do you do?
You must multiply the decimal they are talking about by the TOTAL number of people surveyed.
Tell what the four transformations are AND what they mean.
Translation - slide
Reflection - flip
Rotation - turn
Dilation - get bigger or smaller
What is the slope formula AND what is slope-intercept form?
y2 - y1 / x2 - x1
y = mx + b
How do you get rid of a power of two?
Take the square root
What is a rational number?
CAN be written as a fraction. In decimal form, it is either terminating (comes to an end) or repeating.
Fill in the blanks:
If you have two bases that are the same and being multiplied, you _____ the exponents.
If you have one base with two exponents, you _______ the exponents.
If you divide bases that are the same, you ______ the exponents.
ADD
MULTIPLY
SUBTRACT
What does congruent mean when it comes to shapes AND which of the four transformation does not result in a congruent figure?
Congruent - same size and same shape
Dilation
If they give you a table, graph, and/or equation, and ask you what a possible rate between them is, what do you do?
Find the rate (slope) of the two things they give you, then pick a number between those two rates.
How do you click the cube root button on a calculator?What does the exponent button look like if you want to put in any exponent?
"2nd" then "0"
yx above the division sign
What is an irrational number?
When they give you a scientific notation problem and ask, HOW MANY TIMES GREATER, you have to _______ the two things they are asking about.
DIVIDE
