Answer:
y = 50x+25
f(x) = 50x+25
Step-by-step explanation:
Using the slope intercept form of the equation, y = mx+b
where x is the amount per day and b is the flat fee
2 days
125 = 2x+b
5 days
275 = 5x+b
Subtract
275 = 4x+b
125 = 2x+b
---------------------
150 = 3x
Divide by 3
150/3 = 3x/3
50 =x
The cost per day is 50 dollars
y = 50x +b
Using the data for 2 days
125 = 50*2 +b
125 = 100 +b
125-100 = b
b = 25
The equation is y = 50x+25
f(x) = 50x+25
To graph, The x axis is number of days and the y axis is total cost
The number of days starts with 0, which is the y intercept
Let x = 0, y =25
Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)
The next point plotted ins ( 1,50)
Draw a straight line
Answer:
0.8
Step-by-step explanation:
The annual factor will be found by dividing any year's population by the population of the year before. The points most easily read from the graph are the populations for years 0 and 1. Then the annual factor is ...
factor = (year 1 population)/(year 0 population) = 320/400
factor = 0.8
Add 15 and 12 then divided by 144
Answer:
Step-by-step explanation:
in an isocelles trapezoid, we have the properties:
the lower base angles are congruent
the upper base angles are congruent
we have an angle= 44
the angle #3= 44 because of the properties
so the lower base angles are equal and equal to 44
sum of the angles in trapezoid=360
360-(44*2)=360-88=272
upper base angles are equal
272/2=136
angle1=angle2=136
