Answer:
Class 4: This class of truck has a GVWR of 14,001–16,000 pounds or 6,351–7,257 kilograms. Class 5: This class of truck has a GVWR of 16,001–19,500 pounds or 7,258–8,845 kilograms.
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
because it is a straight line locate at x = 6 that pass to every y coordinate, so it pass -8 too.
Answer:
Correct choice is C.
Step-by-step explanation:
The conic section is represented by equation
First, simplify this equation:
This is the equation of hyperbola with center at point (-3,-4), real semiaxis and imaginary semiaxis Then the distance from the center to the focus is
Then foci are placed at points
Thus, correct choice is C.
Step-by-step explanation:
such an equation is a simple linear function :
y = ax + b
b is in this case the flat fee, and a (the slope) drives the incline of the function for various numbers of students x.
our job is now to find the correct a and b values.
we do this by using the informative we have and create 2 equations for a and b, and then we solve this system.
132.5 = a×25 + b
145 = a×30 + b
now, we can use a little trick and simply subtract the whole first equation from the second equation.
145 = a×30 + b
- 132.5 = a×25 + b
------------------------------
12.5 = a×5 + 0
5a = 12.5
a = 2.5
with this we go into one of the original equations, e.g. the second one :
145 = 2.5×30 + b = 75 + b
70 = b
so, it full equation is
y = 2.5x + 70
the costs for 85 students are
y = 2.5×85 + 70 = 212.5 + 70 = $282.50
