At the beginning of the year, Salma had $35 in savings and saved an additional $8 each week thereafter. Henry started the year with $95 and saved $5 every week. Let SS represent the amount of money Salma has saved tt weeks after the beginning of the year and let HH represent the amount of money Henry has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t,t, and determine the number of weeks after the beginning of the year until Salma and Henry have the same amount of money saved.
Answers
The number of weeks when Salma and Henry would have the same amount of money is 20 weeks.
How many weeks would they have the same amount?The form of the equations that represent the total amount of money saved is :
Total amount in the account = initial amount in the account + (amount added each week x number of weeks)
SS = $35 + ($8 x tt)
SS = $35 + $8tt
HH = $95 + ($5 x tt)
HH = $95 + $5tt
When they have the same amount in their account, the two equations woud be equal.
HH = SS
$95 + $5tt = $35 + $8tt
$95 - $35 = $8tt - $5tt
$60 = $3tt
tt = $60 / 3
tt = 20 weeks

The three more solutions to the given linear equation are (2,-9/2), (6,-3/2), and (5,-9/4).
Given equation:-
y = (3/4)x - 6
We have to create a table of values to obtain ordered pairs.
Also, we have to plot these ordered pairs to create a linear graph and based on the graph we have created, we have to find three more solutions to the equation.
Let x = 0

a. How much does he pay in taxes?
b. What is his net pay?
c. If he receives two paychecks a month, how much will each paycheck be?
Answers
If Lucy earns $15.75 per hour. Last week she worked 25 hours her gross pay is $393.75 . If Lance has a yearly salary of $52,300 and pays 21% in taxes her taxed amount is $10,983, net pay is $41,317 and paycheck is $2,179.
Gross pay1. Gross pay
Using this formula to determine the gross pay
Gross pay = Amount earn per hour × Number of hours worked
Let plug in the formula
Gross pay = $15.75 per hour × 25 hours
Gross pay = $393.75
2a. Taxed amount
Amount in Tax = Salary × Tax percentage
Amount in taxes = $52,300 × 21%
Amount in taxes = $10,983
2b. Net pay
Net pay = Gross - Deduction
Net pay = $52,300 - $10,983
Net pay = $41,317
2c. Paycheck
Paycheck = $52,300 / 24 months
Paycheck = $2,179 per paycheck

The rate of change (m) = 9
The starting number (b) = 100
The equation is: y = 9x + 100
(0, 100) is the ordered pair for the starting number.
See the image for the graph of y = 9x + 100.
How to Create and Graph the Equation of a Line?To create the equation of a line, we need to determine the following:
Y-intercept/starting value = b
Slope of the line/rate of change = m
The ordered pair of the y-intercept or starting value is represented as (0, b), where b is the value of y on the y-axis where the line intercepts the y-axis and x = 0 at this point.
These values can be substituted into y = mx + b, which represents the equation of the line in slope-intercept form.
From the information given, we have:
Y-intercept/starting value (b) = 100
Slope of the line/rate of change (m) = 9
To write the equation of the line, substitute m = 9 and b = 100 into y = mx + b:
y = 9x + 100
The ordered pair for the starting number would be: (0, 100).

Ivan was at the beach. He wanted to spend $12 or less on a beach bike rental. The company he chose

a. Write an inequality for this situation. Let x represent the number of miles ridden.
b. What is the greatest number of whole miles Ivan can ride without going over his spending
limit?
Answers
Using a linear function, it is found that:
a. The inequality for this situation is: 5 + 0.45x ≤ 12.
b. He can ride at most 15 miles without going over the limit.
What is a linear function?A linear function, in slope-intercept format, is modeled according to the following rule:
y = mx + b
In which the coefficients are described as follows:
The coefficient m is the slope of the function, which is the rate of change of the function, that is, the change in y divided by the change in x.The coefficient b is the y-intercept of the function, which is the the value of y when the function crosses the y-axis(x = 0).For the context of this problem, the slope and the intercept are defined as follows:
The slope is the cost per mile, hence m = 0.45.The intercept is the flat cost, the renting fee of b = 5.Hence the cost function, considering x miles, is given as follows:
C(x) = 0.45x + 5.
He wanted to spend $12 or less on a beach bike rental, hence the inequality that models this situation is given by:
C(x) ≤ 12.
5 + 0.45x ≤ 12.
The inequality is solved similarly to an equality, isolating the variable and finding the range of values, hence the solution is found as follows:
0.45x ≤ 7
x ≤ 7/0.45
x ≤ 15.6 miles.
The greatest whole number of miles is of 15 miles, as for 16 miles, the cost would be above $12.

The speed of the second car=48 km per hour
Two cars leave from a place at the same time they travel in opposite directions
The relative speed of the car = Speed of the first car - (- Speed of the second car )

The slope intercept form of a line is given by -
y = mx + c
m is the slope of line
c is the y - intercept
Given is a line that passes through the point (3, 10) and in case [1] is parallel to line y = x - 1 and in case [2] is perpendicular to y = x - 1.
Case 1 - Line is parallel to the line y = x - 1
Assume that the equation of line is -
y = mx + c
Since, the line is parallel, both lines will have same slope and is given by -
m = 1
Since, the line passes through the point (3, 10) we can write -
10 = 1 x 3 + c
c = 7
We can write the equation of line parallel to line y = x - 1 as -
y = x + 7
Case 2- Line is perpendicular to the line y = x - 1 -
Assume that the equation of line is -
y = mx + c
Since, the line is perpendicular, the product of slopes of both lines will be equal to 1. The slope (m) of the line will be -
m x 1 = -1
m = -1
Since, the line passes through the point (3, 10) we can write -
10 = -3 + c
c = 13
We can write the equation of line perpendicular to line y = x - 1 as -
y = - x + 13
