A cell phone provider will allow you to buy a phone over time. They require a $50 initial payment and then charge $25 per month. If this situation were represented by a function, what would be the slope?
Answers
Answer:
25
Step-by-step explanation:
Given that:
Initial payment done for buying the phone = $50
Charges per month for the phone = $25 per month
To find:
The equation to represent the situation and its slope.
Solution:
First of all, let us assume that [tex]m[/tex] represents the number of months for which monthly is to be made.
Charges paid for one month = $25
Charges paid for [tex]m[/tex] months = $25[tex]m[/tex]
Total cost of the phone = Initial payment + Charges paid for [tex]m[/tex] months
[tex]C = 25m + 50[/tex]
It is a linear equation between two variables [tex]C[/tex] and [tex]m[/tex].
This equation can be compared with slope intercept form of a line.
Slope intercept form of a line is represented by:
[tex]y=Mx+c[/tex]
[tex]M[/tex] is the slope.
On Comparing, we get:
[tex]y = C, M = 25, x = m, c = 50[/tex]
Therefore, the slope is 25.

A steel ball is traveling through water with a speed of x meters per second, where x is positive. The drag force, F, in newtons, N, is: F = 0.5 + 0.004(x + 50)(x-2.5). At what speed in meters per second does the ball have a force of 0.5 N, on it?
Answers
Answer:
x = 2.5m/s.
Step-by-step explanation:
Given that F = 0.5 + 0.004(x + 50)(x – 2.5), where x is the speed in m/s and F is the force in N. To know the speed, x, with F = 0.5N, we have:
0.5 = 0.5 + 0.004(x + 50)(x – 2.5)
This gives
0.004(x + 50)(x – 2.5) = 0 (after adding –0.5 to both sides).
For the multiplication to be 0, (x + 50)(x – 2.5) = 0 because 0.004 is not equal to 0.
Hence
x = –50 or x = 2.5
Since it is said from the question that x is positive then x = 2.5m/s.

A cable television repairman charges $35 to go to a customer’s home. He charges an additional $20 per hour for the repair. Petra paid the repairman a total of $85 to come to her home and make a repair. How many hours did it take for the repairs?
Answers
Answer: It took 2 and a half hours for the repairs
Step-by-step explanation:
subtract 35 dollars from the total payed of 85 dollars you're left with 50 dollars we know the repairman charges and extra 20 dollars for every hour he's doing the repairs divide the 50 dollars more she had to pay and divide it by the 20 dollars he charges per every hour he's making repairs and you'll get 2.5 hours
The number of hours used for the repair is 2 1/2 hours.
Let the number of hours used for the repair be represented by h
Based on the information given, the equation to solve the question will be:
35 + (20 × h) = 85
35 + 20h = 85
Collect like terms
20h = 85 - 35
20h = 50
Divide both side by 20
20h/20 = 50/20
h = 2.5 hours
In conclusion, it took 2 1/2 hours for the repair.

The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3x + 2y = 19 ( subtract 3x from both sides )
2y = - 3x + 19 ( divide all terms by 2 )
y = - [tex]\frac{3}{2}[/tex] x + [tex]\frac{19}{2}[/tex] ← in slope- intercept form
with slope m = - [tex]\frac{3}{2}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
