First off need to plot the equation on the graph..
After doing this you determine that the slope of the line it is perpendicular to is 3/7 and it has a y-intercept of 36/7.
Slope intercept is y= mx+b
"m" being the slope and "b" being your y-intercept.
Well..
This isn't your final answer..
All you have to do is reverse the slope by making it negative to make it perpendicular to the line.
So..
Final Answer is: y= -3/7x+36/7 or y= -3/7x+5.142 (rounded to the nearest thousandth).
Multiply the first fraction by 12 and the second one by 5.
Now the equation should be..
48/60 + 55/60
48 + 55 = 103
103/60 = 1 43/60
So the answer is 1 and 43/60
Answer:
3
Step-by-step explanation:
It's given that ΔDEF ∼ΔXYZ . So the corresponding sides of both triangles will be proportional to each other.
DE = 4 ; XY = 4(n + 1) ; EF = 5 ; YZ = 7n - 1
Putting all these values gives ,
Answer:
15.25+15.25=20.50+15.25=35.75.
3 hours will give you $35.75
Step-by-step explanation: All you have to do is add till you have enough
Solve both sides of the equation to graph
