Transformations
What is the rule for Reflection over the x-Axis?
Keep x value the same, change the sign of the y value.
True or False: Any number raised to the zero power equals zero.
False, any number raised to the zero power equals 1.
When solving an equation, the variables cancel and leave 3=6 which type of solution is it?
No solution. 3 does NOT equal 6.
An angle has a measure of 65 degrees. What is the measure of its corresponding angle?
65 degrees because corresponding angles are congruent.
Does a triangle with side lengths of 6, 8, and 10 make a right triangle? Yes or No?
YES
Do not swap the x and y, just change the signs of both x and y values.
What rule is applied to negative exponents found in the numerator of a fraction?
Drop the base and exponent to the denominator and change the sign of the exponent to be positive.
When solving an equation, you get x=10 which type of solution is it?
One solution
The sum of the interior angles in a triangle equals what?
The sum equals 180 degrees.
Solve the equation for x. x2=64
x=8
How many degrees of rotation does each quadrant on the coordinate plane represent?
Each quadrant represents 90 degrees of rotation.
When multiplying like bases what is the rule applied to the exponents?
Keep the base the same and ADD the exponents.
When solving an equation if the Coeficients are the same and the constants are the same which type of solution is it?
Infinitely Many Solutions
One angle in a pair of supplimentary angles equals 55 degrees. Solve for the other angle.
The other angle =125 degrees because 180-55=125
"Daily Double" What range does the first factor have to fall in for a number to be correctly written in scientific notation? (first factor is the number being multiplied with 10 to some power)
The first factor must be at least 1 but less than 10. It can not be greater than 10 or less than 1.
Which transformation is not rigid motion, and why?
Dilation is not rigid motion because it changes the size of the figure.
What value is equal to 35 divided by 32 ?
27
Solve the equation for x. 4x+6 = 2x-2
x=-4
The angle-angle criterion states for triangles to be similar they must have how many pairs of equal angles?
For triangles to be similar they must have at least 2 pairs of equal angles.
Is a number that has a repeating decimal or a terminating decimal considered to be a rational or irrational number?
Rational number
Point A is located at (3, 5) What is A' coordinate after rotating 90 degrees clockwise and translating 2 units down?
A' (5,-5) Swap and change new Y, then subtract 2 from Y.
Simplify the expression (3x3)3
27x9 OR 33x9
The letters from "Don't Call Me After Midnight" actually stand for what? (hint: Steps to help solve equations)
Distribute and draw line, Combine like terms, Move variable to same side, Add or subtract, Multiply or Divide.
What type of angle is formed on alternating sides of a transversal outside of the parallel lines when a transversal cuts through 2 parallel lines?
Alternating Exterior Angles
A right triangle has two legs with lengths of 5 and 12. Solve for the hypotenuse.
The hypotenuse equals 13
