Answer:
Step-by-step explanation:
Let x represent the number of days for which Jim wants to rent the car.
The rental company charges $21 per day to rent a car and $0.10 for every mile driven. He will travel 250 miles. It means that the cost of travelling 250 miles in x days is expressed as
21x + 0.1 × 250
= 21x + 25
If he has $115 to spend, then the inequality that can be used to determine the maximum number of days that Jim can rent a car is
21x + 25 ≤ 115
It depends on how b approaches 0
If b is positive and gets closer to zero, then we say b is approaching 0 from the right, or from the positive side. Let's say a = 1. The equation a/b turns into 1/b. Looking at a table of values, 1/b will steadily increase without bound as positive b values get closer to 0.
On the other side, if b is negative and gets closer to zero, then 1/b will be negative and those negative values will decrease without bound. So 1/b approaches negative infinity if we approach 0 on the left (or negative) side.
The graph of y = 1/x shows this. See the diagram below. Note the vertical asymptote at x = 0. The portion to the right of it has the curve go upward to positive infinity as x approaches 0. The curve to the left goes down to negative infinity as x approaches 0.
4n-7=-3n
add 3n to both sides
and then solve for n
n=1
Answer:
491400
Step-by-step explanation:
Given : A club has 28 members.
To Find : . How many ways are there to choose four members of the club to serve on an executive committee?
Solution:
We are supposed to choose four members of the club out of 28.
So, we will use combination
Formula :
n = 28
r = 4
Substitute the values :
Hence there are 491400 ways o choose four members of the club to serve on an executive committee
