Express x in terms of a and b: b−7x=a−b

Mathematics
1 answer:
quester [9]3 years ago
3 0

Answer:

Step-by-step explanation:

b - 7x = a - b....subtract b from both sides

-7x = a - b - b....combine like terms

-7x = a - 2b....divide both sides by -7

x = (a - 2b) / -7....or it could be written as x = -1/7a + 2/7b

Six customers enter a gift shop during a 3-hour period. On average there are 0.25 customers in the gift shop and each spends 7.5
Stolb23 [73]

Answer:

6 is most directly associated with the flow rate of customers

Step-by-step explanation:

Reason:

0.25 is the number of customers in the gift shop at a given point of time is WIP inventory

7.5 is the average time spent by customer in the shop and it is the throughput time.

Flow rate = WIP inventory/Throughput time

=0.25/7.5

= 0.0333 per minute = 2 per hour or 6 per 3 hour as given in question.

Can you draw different functions that have the same x-intercepts and the same domain and range?
iogann1982 [59]
I'm pretty sure the answer is no.  A function looks like this: f(x) = mx + c.  Let's add another function, f(y) = ny + d.  If the x-intercept is the same, we can subtract c and d from their respective equations. f(x) = mx, f(y) = ny. If the domains are the same, then x and y can have the same value, so we divide it out. f(x) = m, f(y) = n.  Finally, if the ranges are the same, the value of f(x) = f(y).  So by the substitution property, m=n.  Since all the variables equal each other, both functions are equal to f(x) = mx+c!  Therefore, they can only be the same function.

What is 125/275 reduced to lowest terms?​
Lyrx [107]

Answer:

5/11 is your answer.

Step-by-step explanation:

What you do is you need to find a number that goes in to both 125 and 275.

5 goes in to both of them.

125/5=25

275/5=55

25/55 This can still be reduced by 5.

25/5=5

55/5=11

5/11 is your answer.
