y−60=1(x−20) ,
y−40=x ,
y−50=1(x−10) ,
y−45=1(x−5) ,
or
y−55=1(x−15)
Step-by-step explanation: I have no idea
The equation for the graph written in point - slope form may be expressed thus y-60 = 1(x - 20)
The general form of a point - slope expression is :
y - y1 = m(x - x1) m = slopeTaking the pair of points (20, 60) :
x1 = 20 ; y1 = 60Slope = Rise / Run
Rise = (60 - 40) = 20Run = (20 - 0) = 20Slope = 20/20 = 1
Hence, the equation can be expressed thus by substituting the x1 and y1 values into the expression :
y - 60 = 1(x - 20)Therefore, the point - slope expression for the graph is y-60 = 1(x - 20).

Answers
Answer:
Given
The area of a rectangle is less than 81 square centimeters
length 9cm
width =x cm
Step-by-step explanation:
Area of rectangle=length ×width
= 9×X
Area of rectangle is less than 81 cm^2
So 9x-81=0
X=81/9
X=9
So the value of xis 9

Kevin is choosing between two cell phone plans that offer the same amount of free minutes. AT&T’s plan charges $19.99 per month with additional minutes costing $0.35. Verizon’s plan costs $34.99 with additional minutes at $0.30. How many additional minutes, a, will it take for the two plans to cost the same? *
Answers
Answer:
300 minutesStep-by-step explanation:
Step one:
Given data
AT&T’s plan
monthly charge= $19.99
additional charge per minute= $0.35
let the number of minutes be x
let the total charges be
y=0.35x+19.99----------1
Verizon’s plan
monthly charge= $34.99
additional charge per minute= $0.3
let the number of minutes be x
let the total charges be
y=0.3x+34.99----------2
Step two:
equating the two equations above we have
0.35x+19.99=0.3x+34.99
collect like terms
0.35x-0.3x=34.99-19.99
0.05x=15
divide both sides by 0.05
x=15/0.05
x=300
For the two plans to cost the same, it will take 300 minutes

Step-by-step explanation:
Given
[tex]slope\ (m) = \frac{1}{3}[/tex]
[tex]y\ intercept = -5[/tex]
Required
Determine the line equation in slope intercept
The equation of a line in slope intercept is:
[tex]y = mx + b[/tex]
Where
[tex]m = slope = \frac{1}{3}[/tex]
[tex]b = y\ intercept = -5[/tex]
So, [tex]y = mx + b[/tex] becomes

4) A cell phone company would like to run a promotion for a limited time. The cellphone
company is activating a phone line for $40. People will have to pay $50 each month for
phone service. Which equation can be used to find y, the amount that someone will pay
for x months?
y = 40x + 10
y = 40x + 50
y = 40 + 50x
y = 10x + 40
Answers
$40 is the initial price so it stays constant. It never changes.
$50 is the slope because every month they pay $50 so it’s increasing at a constant rate and always stays linear.

Adventureland plans on updating the Arcade with some new and improved games.
They plan on purchasing a new Air hockey table for $875.23, a pinball machine for
$622.19, and two arcade racing games for $942.49 each. What is the total cost for the
new games including an 8.75% sales tax? I will give brainiest
Answers
Answer: $3678.36
Step-by-step explanation:
New airball hockey table = $875.23
pinball machine = $622.19
2 arcade racing games = $942.49 each.= $942.49 × 2 = $1884.98
Total amount without sales tax will be:
= $875.23 + $622.19 + $1884.98
= $3382.4
Sales tax = 8.75% × $3382.4
= 0.0875 × $3382.4
= $295.96
Total cost = $3382.40 + $295.96
= $3678.36

You plan to invest $100 per month for the next 10 years into an account that pays 8% with daily compounding. How much will you have in the account in 10 years?
Answers
Answer:
FV= $18,213.18
Step-by-step explanation:
First, we need to calculate the monthly real interest rate:
Daily interest rate= 0.08/360= 0.00022
Monthly interest rate= (1.00022^30) - 1
Monthly interest rate= 0.0066
Assuming a year of 360 days, and months of 30 days.
Now, we can determine the future value of the investment:
Monthly deposit= $100
Number of periods= 10*12= 120
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
FV= {100*[(1.0066^120) - 1]} / 0.0066
FV= $18,213.18

Answers
Answer:
y = 2/3x - 8
Step-by-step explanation:
Use the slope intercept form, y = mx + b, where m is the slope and b is the y intercept
Plug in the slope and y intercept:
y = mx + b
y = 2/3x - 8
So, y = 2/3x - 8 is the equation of the line.

What is a expression? What is a mathematical equation? What is Equation modelling ?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is the following inequality -
[tex]$\frac{2}{3} < \frac{x}{5} < \frac{6}{7}[/tex]
We can write -
x/5 > 2/3
x > 10/3
x > 3.33
and
x/5 < 6/7
x < 30/7
x < 4.29
[x] can be any number between -
3.33 < x < 4.29
Therefore, [x] can be any number between -
3.33 < x < 4.29.

What is Straight line?a line is an infinitely long object with no width, depth, or curvature. Thus, lines are one-dimensional objects, though they may exist in two, three, or higher dimension spaces.
In the given figure, we need to find the value of x which makes the lines m and n are parallel.
parallel lines are coplanar straight lines that do not intersect at any point. Parallel planes are planes in the same three-dimensional space that never meet.
In the given figure we have two angles 6x+14 and 134.
We need to equate these to find the value of x.
6x+14=134
Subtract 14 from both sides
6x=134-14
6x=120
Divide both sides by 6
x=20
Hence for the value of x =20 will result in lines m and n being parallel
