Answer:
B, D
Step-by-step explanation:
In dollars per hour, the rates are ...
A. $1200/(48 h) = $25/h
B. $500/(50 h) = $10/h
C. $750/(25 h) = $30/h
D. $1500/(150 h) = $10/h . . . . matches B
E. $800/(40 h) = $20/h
Choices B and D are the same, at $10/hour.
Answer:
The lines are parallel
Step-by-step explanation:
x - y = 2
Solving for y
-y = -x+2
y = x -2
And the other equation is
y = x+1
These are both in slope intercept form
We notice that the slopes are both 1, but the y intercepts are different
That means the lines are parallel, but have different y intercepts
Answer:
a) -20/11 b) -10/7
Step-by-step explanation:
a) m=(y2-y1)/(x2-x1)
m=(-4-16)/(4-(-7))
m=-20/(4+7)
m=-20/11
b) m=(y2-y1)/(x2-x1)
m=(-10-(-20))/(-12-(-5))
m=(-10+20)/(-12+5)
m=10/-7
m=-10/7
You can make a proportion.
2.5 x
---- = ----
10 12
then cross multiply and divide
12 times 2.5=30 divide by 10=3
3 inches is your answer
