Answer:

$\text{d) }p=0.35x+85$

Step-by-step explanation:

Since the 85 dollar fee is fixed, there should be no coefficient or constant that accompanies it. However, the total cost of the miles is directly proportional to the number of miles he drives. Thus, 0.35 should be accompanied by a constant that represents the total number of miles he drove. In this case, that constant is $x$ and $0.35x$ will represent the cost from the number of miles he drives in addition to the 85$ flat fee, hence $\implies \boxed{\text{d) }p=0.35x+85}$

What does it mean for a function to have an absolute extreme value at a point c of an interval [a,b]

tekilochka [14]

Hello from MrBillDoesMath!

Answer: Suppose the function is f(x). The statement means that either:

1) f(c) >= f(x) for x in the interval [a,b]

2) f(c) <= f(x) for x in the interval [a,b]

That is, the value of f(c) is larger (or smaller, take your choice) than the value of f(x) for all other x in the interval. Equivalently, f(c) is the largest (or smallest) value of f(x) in the interval.

How many 30 are there in 600

strojnjashka [21]

The question that is asked is pretty straight forward. Only thing that needs to be found is the number of 30 in the number 600. By dividing 600 by 30 we can arrive at the desired result.
Number of 30 in 600 = 600/30
   = 60/3
   = 20
So there are 20 number of 30s in the number 600. This method can be used to find answers to several other similar kind of questions like the number of 10s in 1000.Following the same procedure we get
Number of 10 in 1000 = 1000/10
   = 100

The width of a rectangle is the length minus 7 units. The area of the

AleksandrR [38]

Answer:

8 units

Step-by-step explanation:

here's your solution

=> let the length of rectangle be X

=> then width = x - 7

=> area = 8units

=>> area = length*width

=> area = x (x-7) = 8

=> x^2 - 7 = 8

=> now, x^2 - 7x - 8 = 0

=> factories the above equation by middle term split

=> x^2 - 7x - 8

=> x^2 - 8x + x - 8

=> take the common

=> x(x - 8) + 1(x - 8)

=> (x + 1) (x - 8)

neglect (x + 1) because this will in negative for X

=> x - 8 = 0

=> x = 8

=>so, x = 8

=>length = 8 units
