Answer:
y = -3x - 2
Step-by-step explanation:
Equation of a line passing through [tex](x_1,y_1)[/tex] and slope m is,
[tex]y-y_1=m(x-x_1)[/tex]
Slope of a line passing through [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line passing through (0, -2) and (1, -5) will be,
Slope = [tex]\frac{-2+5}{0-1}[/tex]
m = - 3
Therefore, equation of the line passing through (0, -2) and slope = -3 will be,
y + 2 = -3(x - 0)
y + 2 = -3x
y = -3x - 2
Nami is wrapping packages with green and pink ribbon.She has 11.85 meters of green ribbon and 13.4/of pink ribbon. How many more meters of pink ribbon are their than green?
Given :
Nami is wrapping packages with green and pink ribbon.
She has 11.85 meters of green ribbon and 13.4 of pink ribbon.
To Find :
How many more meters of pink ribbon are their than green.
Solution :
Length of green ribbon, g = 11.85 m .
Length of pink ribbon, p = 13.4 m .
Amount of pink more than green is :
A = 13.40 - 11.85
A = 1.55 m
Therefore, pink ribbon is 1.55 meter more than green one.
Hence, this is the required solution.
If you can bicycle 8 miles per hour, how many minutes will it take to bicycle 4 miles?

The length a rectangular pan is represented by 5a2 and the area of the rectangular pan is represented by 5a4 + 10a3 - 15a2, find the polynomial expression that represents the width of the pan. Write your answer in descending order. Please use the palette below to enter your answer
Answer:
[tex]Width = a^2 + 2a - 3[/tex]
Step-by-step explanation:
Given
[tex]Area = 5a^4 + 10a^3 - 15a^2[/tex]
[tex]Length = 5a^2[/tex]
Required
Determine the Width
The area of a rectangle is calculated using:
[tex]Area= Length * Width[/tex]
Make Width the subject
[tex]Width = \frac{Area}{Length}[/tex]
Substitute values for Area and Length
[tex]Width = \frac{5a^4 + 10a^3 - 15a^2}{5a^2}[/tex]
Factorize the numerator
[tex]Width = \frac{5a^2(a^2 + 2a - 3)}{5a^2}[/tex]
[tex]Width = a^2 + 2a - 3[/tex]
Hence, the polynomial for the width of the rectangle is:
[tex]Width = a^2 + 2a - 3[/tex]

If 3x - 9y = 21 and 6x + 3y = 21, which of these could be a value of x or y? Select all that apply.
Answer:
x = 4
y = -1
Step-by-step explanation:
3x-9y = 21
6x+3y =21
-2* (3x-9y) = -2*(21)
6x+3y = 21
-6x+18y = -42
6x+ 3y = 21
-6x+6x+18y+3y = -21
21y = -21
y --21/21
y = -1
3x-9y =21
3x - 9*(-1) = 21
3x + 9 =21
3x = 21-9
3x = 12
x = 12/3
x = 4

He original price of a couch was $395.00. A store will markup the price of the couch by 25%. What is the exact price of the couch, not including tax, with this markup
Answer:
The exact price of the couch is $493.75
Step-by-step explanation:
Here, we want to find the price of the couch given the mark up percentage
Mathematically, that would be;
395 + (25% of 395)
= 395 + 25/100 * 395
= 395 + 395/4
= 395 + 98.75
= $493.75

The constant of variation for a function that is a direct variation and whose graph passes through the point (5,82) is 16.4
For a graph with x and y-axis, we can say that y is directly proportional to "x" since it is a direct variation.
If y is directly proportional to x, this is expressed as:
y = kx
k is the required constant of variation.
Since the graph passes through the point (5,82), this shows that x = 5 and y = 82
Substituting into the formula:
82 = 5k
k = 82/5
k = 16.4
Hence the constant of variation for a function that is a direct variation and whose graph passes through the point (5,82) is 16.4

Answer:
$4(12)
$48
Step-by-step explanation:
The problem is telling you fees are $4 per month. It is asking the amount of fees for a year.
You find the yearly amount by multiplying the monthly amount by the number of months in a year:
(fees for year) = (fee for month)×(number of months in a year)
All it is asking for is the product expression:

Students make 97.5 ounces of liquid soap for a craft fair. They put the soap in7.5 -ounce bottles and sell each bottle for $4.50. How much do the students earn if they sell all the bottles of liquid soap? Explain.
Answer:
$58.5Step-by-step explanation:
Step one:
given data
the total amount of ounces= 97.5 ounces
we are told that the capacity of one bottle is 7.5 ounce
this means that they can actually fill up 97.5/7.5= 13 bottles
Step two:
We are told that one bottle was sold for $4.5
Hence they will sell 13 bottles for 13*4.5= $58.5

Jack wants to buy a coat that costs $74.95. The sales tax rate in his city is 6,4%. What is the total cost for the coat? Round to the nearest cent
Answer:
$79.7468
Step-by-step explanation:
6.4% of 74.95 is 4.7968, since 6.4 * 74.95 is 479.68, and if you divide that by 100, you will get 4.7968. 4.7968 + 74.95 = $79.7468
Here we want to find the total cost of a coat given that we know its cost and the sales tax.
By working with percentages, we will find that the total cost will be $79.75
Applying the tax:
So the cost of the coat is $74.95, and then we must pay an extra 6.4%
Then we must pay a total of the 100% + 6.4% = 106.4%
And the 100% is equivalent to $74.95
Then the 106.4% is equivalent to:
(106.4%/100%)$74.95 = $79.75
So the total cost of the coat is $79.75

Mackenzie works as a salesperson at an electronics store and sells phones and phone accessories. Mackenzie earns a $10 commission for every phone she sells and a $4 commission for every accessory she sells. On a given day, Mackenzie made a total of $126 in commission and sold 7 more accessories than phones. Write a system of equations that could be used to determine the number of phones sold and the number of accessories sold. Define the variables that you use to write the system.
Answer:
Let p= the number of phones sold
Let a= the number of accessories sold
Step-by-step explanation:
10p+4a=126
a=p+7
The system of equation should be 10p+4a=126 and a=p+7
Given that,
Mackenzie earns a $10 commission for every phone she sells and a $4 commission for every accessory she sells. On a given day, Mackenzie made a total of $126 in commission and sold 7 more accessories than phones.Based on the above information, the equation is as follows:
Here we assume p= the number of phones sold
And, a= the number of accessories sold
