But u didnt asked any question?
what is
the equation of the line that passes through the points (-6,6) and (-1,-9)
Answer:
The answer to the question provided is y = -3x - 12.
Step-by-step explanation:
❃Incase you forgot what the linear equation formula is ☟
[tex]y = mx + b[/tex]
❃Incase you also forgot, what the slope formula is ☟
[tex]m = \frac{y_2 - y_1 }{x_2 - x_1}[/tex]
➊ First: We are going to be solving for the slope.
[tex]m = \frac{ - 9 - 6}{ - 1 - ( - 6)} = \frac{ - 15}{ \: \: \: 5} = - 3[/tex]
➋Second: We find the y-intercept.
[tex]y = mx + b \\ 6 = - 3( - 6) + b \\ 6 = 18 + b \\ \frac{ - 18 = - 18 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 12 = b}[/tex]

Which statement about the shipping rate is true?
Shipping at the second rate will always cost $1.60 more than shipping
at the first rate.
If the weight is greater than 16 ounces, the shipping rate is $0.35 per
ounce, plus $1.60.
It is possible that an item weighing less than 16 ounces could cost the
same as an item weighing more than 16 ounces.

Answer:
A: Shipping at the second rate will always cost 1.60 more than shipping at the first rate.
Step-by-step explanation:
The following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that the Quick Ship company uses the function C(w) to calculate the cost in dollars {C} for shipping an item weighing {w} ounces as
C(w) = 0.35W + 1.6 if {w > 16}
The given function is -
C(w) = 0.35w + 1.6 if {w > 16}
We can conclude the following points for the function C(w) -
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.Therefore, the following points for the function C(w) can be concluded as
The function C(w) is valid only for {w} greater than 16 ounces.The initial cost is $1.6.The cost of shipping per ounce is $0.35.To solve more questions on algebraic expressions, visit the link below -

If 38% of a number, n, is 24.32, what is 20% of n?
Answer:
20 % of n would be 12.8
Step-by-step explanation:
By first finding that 24.32 is 38% of 64. To find that you would have the fractions 38/100 = 24.32/n. From there you cross multiply the 100 times 24.32 then divide that answer by 38 to get the answer 64. you take that n=64 and find 20% of that which is 12.8.
The 20% of n is 12.8
38% of number n is given as:
[tex]38\% \times n = 24.32[/tex]
Express the percentage (38%) as decimal
[tex]0.38 \times n = 24.32[/tex]
Divide both sides of the equation by 0.38
[tex]n = 64[/tex]
Multiply both sides of the equation by 20%
[tex]20\% \times n = 20\% \times 64[/tex]
Express the percentage (20%) as decimal
[tex]20\% \times n = 0.20 \times 64[/tex]
Evaluate the product
[tex]20\% \times n = 12.8[/tex]
Hence, the 20% of n is 12.8

Greg buys apples, bananas, and kiwis from a fruit stand each week. The first week he pays $3.19 for 2 apples, 3 bananas, and 2 kiwis. The second week he pays $4.12 for 3 apples, 4 bananas, and 2 kiwis. The third week he pays $3.01 for 1 apple, 1 banana, and 4 kiwis. Choose the system of equations that can be used to solve for the number of apples,a, the number of bananas,b, and the number of kiwis,k.
Answer:
Step-by-step explanation:
2a+3b+2k= $3.19
3a+4b+2k=$4.12
1a+1b+4k=$3.01
The system of equation that can be used to solve these scenario are 2a + 3b + 2k = 3.19, 0a + 4b + 2k = 4.12 and 1a + 1b + 4k = 3.01.
What is a linear equation?A linear equation consist of variables and constant sperated by arithmetic operations which has highest degree of 1.
We know that a system of equations is formed when we have two or more than two linear equations in two or more than two variables and a system of equations is consistent when the number of variables is equal to or less than the number of equations.
Given in this questin is 3 variables Applles(a). Bananas(b) and Kiwis(k) and we can form three equations in three variables they are,
2a + 3b + 2k = 3.19...(i)
0a + 4b + 2k = 4.12...(ii)
1a + 1b + 4k = 3.01...(iii)
We can solve this system of equation by first multiplying eqn(iii) by 2 and then subtracting it from eqn(i) to eliminate variable 'a' and then equating with eqn(ii) to eliminate variable 'b' or 'k'

The ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3.
If there are 48 paintbrushes, how many bottles of paint are there?
Answer:
Well, 48 divided by 8 is 6. And 6 times 3 is 18. So I belive that there would be 18 bottles of paint.
Step-by-step explanation:
The number of bottles of paintbrushes is 18.
What is a fraction?Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A ratio shows how often one number is contained in another.
For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.
Given that the ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3. If there are 48 paintbrushes.
The number of the bottles will be calculated as:-
P / B = 8 / 3
3P = 8B
3 x 48 = 8B
B = 3 x 6
B = 18
Therefore, the number of bottles of paintbrushes is 18.

Find each unknown number. a. 12 is 150% of what number? b. 5 is 50% of what number? c. 10% of what number is 300? d. 5% of what number is 72? e. 20 is 80% of what number?
The unknown values of number for each of the expression is 8, 10, 3000, 1440, and 25.
What is Percentage?A percentage is a portion of a whole number which is expressed as a number between the range of 0 and 100 rather than as a fraction. All of a thing is 100 percent, half of it is 50 percent, and none of something is zero percent. To determine a percentage, we divide the portion of the whole through the whole of itself and multiply it by 100.
x × 150/100 = 12
x = 12 × 100/ 150
x = 1200/ 150
x = 8
x × 50/100 = 5
x = 5 × 100/ 50
x = 500/ 50
x = 10
x × 10/100 = 300
x = 300 × 100/ 10
x = 30000/ 10
x = 3000
x × 5/ 100 = 72
x = 72 × 100/ 5
x = 7200/ 5
x = 1,440
x × 80/ 100 = 20
x = 20 × 100/ 80
x = 2000/ 80
x = 25
Therefore, the values of unknown numbers are 8, 10, 3000, 1440, and 25, respectively.

Answer:

What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To determine how many blankets can fit in a 22-inch moving box, we first need to calculate the volume of the box.
Since the box is 22 inches in all three dimensions (length, width, and height), its volume is:
= 22 x 22 x 22
= 10,648 cubic inches
Next, we need to divide the volume of the box by the volume of one blanket to find out how many blankets can fit inside.
= 10,648 / 704
= 15.125
We can't fit a fraction of a blanket, so we can only pack a whole number of blankets.
Therefore,
We can pack a maximum of 15 blankets into the 22-inch moving box.
