Quadratics
What are the three other names for X-intercepts
zeros, roots, and solutions.
When graphing an inequality you want the ____ on the left
The Y
What is an Arithmetic Sequence?
A sequence with a pattern that involves addition.
Taking the max number and subtracting it from the min number is what?
Finding Range
What are Consecutive Integers?
unbroken sequence, integer is ONE more than the previous number
The name of a quadratic graph?
Parabola
What will happen if you divide or multiply by a negative?
The sign will switch
What is the common difference in the pattern 6, 10, 14, 18, 22
adding 4
Find the mode for the data set 3,6,5,6,10,4,4,10,6,11
The mode is 6 since it is being repeated the most
What are Consecutive Odd/Even Integers?
Odd numbers that follow each other and differ by 2 as well as Even numbers that follow each other and differ by 2.
Determine how many solutions the equation x2-18x+81 has *use desmos*
The equation has one solution meaning one point touches the x-axis
What type of line with a "Greater Than" symbol have? Where would it be shaded on the graph?
dotted line and would be shaded above the line.
What would the recursive formula be if the common difference for a sequence is 6.
an=an-1+6
What is the most common average?
The Mean
The largest number is 18. if 1 integer=x and Integer 2=x+1 then you get 2x+1=35 when you add them together, subtract 1 on both sides and then divide by 2, you will get x by itself then add one to find the largest number
What is the Axis of Symmetry for -x2-20x+36 *use desmos*
The Axis of Symmetry is x=-10
In the inequality 3x+2y<6, what is the first step in order to find the slope and y-intercept.
subtract 3x on both sides of the inequality
What is your start term in the sequence 9, 14, 19, 24 if 9=term #1 and the common difference is 5?
The start term is 4, subtract 5 from 9
Find the mean for the data set, 14,3,18,16,18,14,25,28,14,31,2,3
The mean is 15.5 when you add all the numbers together and divide by 12
The sum of two consecutive even integers is 46. What are the two consecutive even integers?
22 and 24. the first even integer is x and the second even integer is x+2, when you add those together you get 2x+2=46, subtract 2 on both sides and then divide 2 on both sides. Your x will be 22 then add 2 to that to get 24.
Factor x2+10x+16
(x+2)(x+8) x*x=x2 and 2+8=10, 2*8=17
In the inequality 10x-5y>20, find the slope
The slope is 2, subtract 10x on both sides to get 20-10x then divide by -5 to get 2
In a sequence if the terms 10,11,12,13 are 24, 18, 12, 6 in that order, what is the 20th term?
It would be -36, if you keep adding -6 until you get to the 20th term it will give you -36
What is the Standard Deviation for the following set 12, 10, 23, 28, 11, 3, 25, 1, 30, 18, 14, 18, 23, 12, 11*use desmos*
The Standard Deviation is 8.63
The sum of two consecutive odd integers is 56. What is the smallest number?
27 is the smallest number. If integer one is x and integer two is x+2 and you add them you get 2x+2=56, you subtract 2 on both sides and then divide 2 on both sides and you get x by itself which is 27. X is the smallest and x=27 therefore that is the answer.
