y=7x+3
What is the X called in this equation
A Variable
What would you call these lines?
Parallel lines
What is absolute value?
The distance a number is from 0
What is the absolute value of |-56|
56
An angle that is less than 90 degrees
What is the top number in a fraction called? Example: 1
Numerator
What do these red dots on this graph represent?
verticies
What does it mean to find the "median" of a list of numbers?
The middle number when the list of numbers is in order.
Example: If you had 40, 10, 30, 20, 70, 15, 12
Step 1- put the numbers in order
10, 12, 15, 20, 30, 40 70
Step 2 - find the number that is in the middle
the median is 20
B. 9
What is an obtuse angle?
An angle that is more than 90 degrees
What is the bottom number in a fraction called?
Denominator
What is this called? When the sides of one triangle are equal to those on the other?
Congruent
Find the average of the numbers
Example: Find the mean of 10, 20, 40, 70, 80
Step 1: 10+20+40+70+80=220
Step 2: DIVIDE 220 / 5 (because there are 5 numbers in total) = 44
The mean is 44
Solve this expression 6 - (1 x 4) - 2
0
180 degrees
5X2 + 8y = 2
what are the numbers next to variables called? (in the equation it is the 5 and 8)
Coefficents
What are the four different sections on a graph called?
Quadrants
What does it mean to find the "mode" of a list of numbers?
The number that appears most often
Example: 1,3,4,5,6,5,4,3,3,2,3,6,3
the mode would be 3 because it appears the most
Given what you know about parallel lines, find x.
X=35
Find the missing angle
65 degrees
In this equation tell me the slope (300) AND the y intercept (200)
y=2x+3
slope- 2
Y intercept - 3
If I asked you to find the inside of a triangle what am I asking you to find? Respond with: its _______ PART TWO if I were to ask you to find the outside of a triangle what am I asking you to find? Its _______
What does it mean to find the "range" of a list of numbers?
EX: 6,2,7,3,9,4,1
Step 1: find your biggest number 9
Step 2: find your lowest number 1
Step 3: Subtract your highest number from your lowest number
9-1=8
Range is 8
Find n
n=24
