The distributive property is when you distriute numbers if they are getting multiplied by the same number.
Example:
Original Equation: A(B+C)
Distribute the equation so that B and C are by itself.
New Equation: AxB + AxC
This is distributive property.
What is the equation of the line that passes through the point (6,-2) and has a slope of -3/2
Let's use the point-slope formula to write the equation of this line.
The point-slope formula is y - y₁ = m(x - x₁).
In the formula, x₁ and y₁ are points and the m is our slope
Now let's substitute.
y + 2 = -3/2(x - 6).
Notice that I put y + 2 above since y - (-2) means y + 2.
Now distribute the -3/2 through the parentheses.
This gives us -3/2x + 9.
Bring down your y + 2 and we have y + 2 = -3/2x + 9.
To put this in standard form, we need to multiply both
sides by 2 because we can't have any fractions.
This gives us 2y + 4 = -3x + 18.
Now move the +4 to the right by subtracting
4 from each side to get 2y = -3x + 14.
Now move your x term to the right by adding 3x to both sides.
So our final answer reads 3x + 2y = 14.

A department store will place a sale item in a special display for a one-day sale. Previous experience suggests that 43 percent of all customers who pass such a special display will purchase the item. If 1,462 customers will pass the display on the day of the sale, and if a one-item-per-customer limit is placed on the sale item, how many units of the sale item should the store stock in order to have at most a 1 percent chance of running short of the item on the day of the sale? Assume here that customers make independent purchase decisions. (Round your answer to nearest whole number.)
Number of units?
Answer:
672.7436 units of the sale item should the store stock in order to have at most a 1 percent chance of running short of the item on the day of the sale
Step-by-step explanation:
No. of customers pass the display on the day of sale = 1462
Proportion of people will purchase if pass such a special display = 0.43
Mean = E(X)=np
E(X)=[tex]1462 \times 0.43[/tex]
E(X)=628.66
Standard deviation = [tex]\sqrt{npq}[/tex]
Standard deviation =[tex]\sqrt{1462 \times 0.43 \times (1-0.43)}=18.92[/tex]
Now we are supposed to find how many units of the sale item should the store stock in order to have at most a 1 percent chance of running short of the item on the day of the sale
P(X<x)=0.01
Using z table
[tex]P(\frac{x-\mu}{\sigma})= 2.33 \\\frac{x-628.66}{18.92}=2.33\\x=(2.33 \times 18.92)+628.66\\x=672.7436[/tex]
Hence 672.7436 units of the sale item should the store stock in order to have at most a 1 percent chance of running short of the item on the day of the sale
The number of units should be 672.7436 units.
Calculation of number of units:Since No. of customers pass the display on the day of sale is 1462 and the proportion of people who will purchase if pass such a special display is 0.43
So,
Mean should be = 43% of 1,462
= 628.66
Now the standard deviation should be
[tex]= \sqrt{1462 \times 0.43 \times (1-0.43)}[/tex]
= 18.92
Now the number of units should be
[tex]x - 628.66 \div 18.92 = 2.33[/tex]
x = 672.7436

Step-by-step explanation:
The New England Cheese Company produces two cheese spreads by blending mild cheddar cheese with extra sharp cheddar cheese. The cheese spreads are packaged in 12-ounce containers, which are then sold to distributors throughout the Northeast. The Regular blend contains 65% mild cheddar and 35% extra sharp, and the Zesty blend contains 75% mild cheddar and 25% extra sharp. This year, a local dairy cooperative offered to provide up to 8100 pounds of mild cheddar cheese for $1.30 per pound and up to 3500 pounds of extra sharp cheddar cheese for $1.50 per pound. The cost to blend and package the cheese spreads, excluding the cost of the cheese, is $0.30 per container. If each container of Regular is sold for $1.80 and each container of Zesty is sold for $2.10, how many containers of Regular and Zesty should New England Cheese produce
Answer:
They would produce 14,400 packages of zetsy and the regular profit making would be $11,340.
Step-by-step explanation:
12-ounce
regular = 65%
mild = 35%
extra sharp zesty blend = 75%
extra sharp mild = 25%
8,100 mild for = $1.30
3,500 extra sharp = $1.50
cost blend and package = $0.30
regular sold = $1.8
zesty = $2.10
first we calculate the cost of each product
conversion Of ounces to pounds:
1 pound = 16 ounces
regular cost:
12/16 pounds x 65% mild x $1.30
= 0.63375
12/16 pounds x 35% sharp x $1.50
= 0.39375
+ blend and package $0.30
total = $1.3275
contribution: $1.8 – $1.3275
= $0,4725
zesty cost:
12/16 pounds x 75% mild x $1.30
= 0.73125
12/16 pounds x 25% sharp x $1.50
= 0.28125
+ blend and package 0.30
total $1,3125
contribution: $2.10 – $1.3125
= $0,7875
to maximize profit:
profit = $0.4725Regular + $0.7875zetzy
adding the constraint:
mild = Regular x $0.4775 + Zetzy x $0.5625 = 8,100
and
sharp = Regular x $0.2625 + Zetzy x $0.1875 = 3,100
contribution generated by each product/pound:
Regular Zesty
CM $ 0.47250 $ 0.47250
Constrain resource
( pounds of mild) 0.48750 0.56250
CM per constrain $ 0.9692 $ 1.4000
Constrain resource
( pounds of sharp) 0.26250 0.18750
CM per constrain $ 1.80 $ 4.20
As zesty is better we produce as much as we can:
8,100 pounts / 0.5625 per cheese spreads: 14,400
check for possibilities of other constraint:
14,400 zesty packages x 0.1875 pounds each = 2,700 pounds
because it’s possible we only produce zetsy
profit = $0.4725 (0) + $0.7875 (14,400)
profit = $ 11,340

1. whats the midpoint between (7,3) and (-3,-1)
Answer:
(2, 1 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )
Here (x₁, y₁ ) = (7, 3) and (x₂, y₂ ) = (- 3, - 1) , then
midpoint = ( [tex]\frac{7-3}{2}[/tex], [tex]\frac{3-1}{2}[/tex] ) = ( [tex]\frac{4}{2}[/tex], [tex]\frac{2}{2}[/tex] ) = (2, 1 )
A rectangular table top has an area of 8ft and a perimeter of 12ft.What are the dimensions of the table?
Answer:
Dimensions are 2 and 4
Step-by-step explanation:
Area= a*b=8
Perimeter=2(a+b)=12 => a+b = 12/2. a+b = 6
a+b=6 =>a=6-b
If a=2=>b=4 so 4+2=6 , 4*2=8 and 4*2+2*2=12
If a=4=>b=2 so 4+2=6 , 4*2=8 and 4*2+2*2=12
Dimensions are 2 and 4
The possible dimensions of the table are -
L = 2, B = 4.
or
L = 4, B = 2.
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 a rectangular table top has an area of 8 ft and a perimeter of 12 ft.
Let the dimensions of the rectangular table be {x} ft and {y} ft respectively.
We can write -
xy = 8 ....... Eq(1)
2(x + y) = 12
x + y = 6 ....... Eq(2)
y = (6 - x)
Then, we can write -
x(6 - x) = 8
- x² + 6x = 8
x² - 6x + 8 = 0
(x - 2)(x - 4) = 0
We get -
x = 2 and x = 4
Now,
For x = 2, y = 4.
For x = 4, y = 2.
Therefore, the possible dimensions of the table are -
L = 2, B = 4.
or
L = 4, B = 2.

A store is having a sale on almonds and jelly beans. For 2 kilograms of almonds and 3 kilograms of jelly beans, the total cost is $11. For 6 kllograms of almonds and 5 kilograms of jelly beans, the total cost is $23. Find the cost for each kilogram of almonds and each kilogram of jelly beans.
Find cost for each kilogram of almonds :?
Ans find the cost for each kilogram of jelly beans :?
Answer:
The cost of each kg of almonds is $1.75
The cost of each kg of jelly beans is $2.5
Step-by-step explanation:
We will use the system of linear equations to solve the question
Assume that the cost of 1 kg of almonds is $x, and the cost of 1 kg of jelly beans is $y
∵ For 2 kilograms of almonds and 3 kilograms of jelly beans,
the total cost is $11
→ Multiply 2 by x and 3 by y, then equate their sum by 11
∴ 2x + 3y = 11 ⇒ (1)
∵ For 6 kilograms of almonds and 5 kilograms of jelly beans, the
total cost is $23
→ Multiply 6 by x and 5 by y, then equate their sum by 23
∴ 6x + 5y = 23 ⇒ (2)
Now we need to solve this system of equations to find the values of x and y
→ Multiply equation (1) by -3 to make the coefficient of x in it equals
the coefficient of x in equation (2) in values and differences in signs
∵ -3(2x) + -3(3y) = -3(11)
∴ -6x + -9y = -33 ⇒ (3)
→ Add equations (2) and (3) to eliminate x
∵ (6x + - 6x) + (5y - 9y) = (23 + -33)
∴ -4y = -10
→ Divide both side by -4 to find the value of y
∵ [tex]\frac{-4y}{-4}=\frac{-10}{-4}[/tex]
∴ y = 2.5
→ Substitute the value of y in equation (1) to find x
∵ 2x + 3(2.5) = 11
∴ 2x + 7.5 = 11
→ Subtract 7.5 from both sides
∵ 2x + 7.5 - 7.5 = 11 - 7.5
∴ 2x = 3.5
→ Divide both sides by 2 to find the value of x
∵ [tex]\frac{2x}{2}=\frac{3.5}{2}[/tex]
∴ x = 1.75
∵ x represents the cost of 1 kg of almonds
∴ The cost of each kg of almonds is $1.75
∵ y represents the cost of 1 kg of jelly beans
∴ The cost of each kg of jelly beans is $2.5

The cost of a lamp was reduced from $40 to $22.
By what percent did the cost of the lamp decrease?
A 4.5%
B 25%
C 35%
D 45%
Answer:
45 %
Step-by-step explanation:
decreasing by half would be 50 percent making it only 20 dollars. In this situation it is 2 dollars more. 45 percent of 40 is 18. subtract: 40-18=22
The decreased percent of the cost of the lamp is 45%.
What is a percentage?A percentage is expressed as a number or ratio that can be expressed as fraction of 100. It is denoted by % symbol.
The cost of a lamp was reduced from $40 to $22.
Initial price = $40
Final price= $22
Decreased percentage =[tex]\frac{initial price-final price}{initial price} *100[/tex]
=[tex]\frac{40-22}{40} *100[/tex]
= 45%
Hence, the decreased percent of the cost of the lamp is 45%.
