Answer:
Third option {(-3,4),(-1,5),(0,7),(2,2),(5,7)}
Step-by-step explanation:
I think
Find the slope of the first line, that is the difference of the y’s over the difference of the x’s. This way: 2-5/2-5=-3/-3 which equals 1
Now find the slope of the second line 2-(-6)/-5-3
=8/-8
=-1
The slopes are opposite reciprocal ( you could also say that the product of the 2 slopes equals -1) therefore the lines are perpendicular.
Step-by-step explanation:
plug in 1 and 4 for x and y
(4)=2(1)-5
then do the math
4=2-5
4 does not equal -3 therefore it is not a solution
Answer:
m<EAB=135
Step-by-step explanation:
m<FAD=30
m<EAF=90
180-90-30=60
m<EAC=60
180=60+5x+3x
-60 -60
120=8x
/8 /8
x=15
m<EAB=60+5x
m<EAB=60+5(15)
m<EAB=60+75
m<EAB=135
Answer:
hours worked; amount of money earned; 0 to 30; $0 to $330
Step-by-step explanation:
Let
y ----> the amount earned per week
x ----> the number of hours worked by week
In this problem
the amount earned per week (variable y) represent the dependent quantity
the number of hours worked by week (variable x) represent the independent quantity
therefore
The domain is the interval -----> [0,30] (the maximum number of hours per week is 30)
The range is the interval -----> [0,11*30] ----> [0,330] (the maximum amount earned per week is $330)
therefore
independent quantity is hours worked
dependent quantity is amount of money earned
domain is 0 to 30
range is $0 to $330
