Step-by-step explanation:
The commutative porperty states that numbers can be swapped over , they can change their place in the equation and the result will still be the same.
In our case 13 x 7 x 21, the commutative property means that the numbers can be rearranged
13x7x21=13x21x7=7x21x13=7x13x21
Answer:
The Answer is A. slope = 1.5 and y-intercept = -2
Step-by-step explanation:
In y=mx+b form b represents your y-intercept and m (or the number next to the x) is your slope
Answer:
The answer to your question is the third option
Step-by-step explanation:
To know if two lines are parallel we must get their slopes if the slopes are equal, the lines are parallel.
Data
A (2,2)
B (3,6)
C(0,5)
D(1,9)
Formula
slope = 
Process
1.- Calculate the slope of line 1
slope 1 = 
slope 1 = 
slope 1 = 4
2.- Calculate slope 2
slope 2 = 
slope 2 = 
slope 2 = 4
3.- Compare the slope
slope 1 = 4 and slope 2 = 4, both slope are equals, then the lines are parallel.
Answer:
5√3 / 2
Step-by-step explanation:
tan 30 = ( 5 / 2 ) / y
1 / √3 = 5 / 2y
2y = 5√3
y = 5√3 / 2
