Yaneev thinks of a number y. He subtracts three from the number, then doubles it. Then he subtracts three again, and doubles the number again. The result is his original number y. What is y?
Answer: y=6
Step-by-step explanation:
The given number is y.
According to the question,
Step 1 . subtracts three from the number (y-3), then doubles it
i.e. Final number = 2(y-3)
Step 2 . subtracts three again i.e. (2(y-3)-3), and doubles the number again
i.e. Final result = 2(2(y-3)-3)
If the result is his original number y, then
2(2(y-3)-3) =y
⇒ 2(2y-6-3)=y [ using distributive property]
⇒ 2(2y-9)=y
⇒ 2(2y)-2(9)=y [ using distributive property]
⇒ 4y -18=y
⇒ 4y -y= 18
⇒ 3y= 18
⇒ y= 6 [Divide both sides by 3]
Hence, y=6
Answer:
y = 6
Step-by-step explanation:
here, lets plug it into the equation.
((y - 3)2) - 3)2 = y
((6-3)2) - 3)2 = 6
6-3 = 3 * 2 = 6 - 3 = 3 * 2 = 6
cook books have recipes that are designed for 4 people. if a particular recipe in a cook book calls for 3 eggs, how many eggs would you need if you were cooking the recipe for 14 people?
Answer:
10.5
Step-by-step explanation:
If the recipe is designed for 4 people than you would need 6 eggs for 8 people (8 is twice as many as 4 so you need twice as many eggs.) similarly, 14 is 3.5 times as many as 4 (14/4=3.5) so you would need 3x3.5=10.5 eggs.

Which point lies on the line with point-slope equation y - 3 = 4(x + 7)?
A.
(7, 3)
B.
(7, -3)
C.
(-7, -3)
D.
(-7, 3)
Answer:
D. (-7, 3)Step-by-step explanation:
The standard form of a point slope equation of a line is expressed as shown;
y-y₀ = m(x-x₀) where;
m is the slope of the line
(x₀, y₀) is the coordinate of the point that lies in the line.
Comparing the standard equation given with the equation in question
y - 3 = 4(x + 7) to get the point on the line we will have;
y₀ = 3 and -x₀ = 7
for -x₀ = 7;
multiply both sides with a minus sign
-(-x₀) = -7
x₀ = -7
Hence the coordinate of the point required (x₀, y₀) is (-7, 3).

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. n2+n
Answer:
Perfect square trinomial: [tex]n^2+n+\dfrac{1}{4}[/tex]
Binomial squared: [tex]\left(n+\dfrac{1}{2}\right)^2[/tex].
Step-by-step explanation:
The given expression is [tex]n^2+n.[/tex]
Here coefficient of n is 1.
Now, find square of half of coefficient of n.
[tex]\left(\dfrac{1}{2}\times 1\right)^2=\dfrac{1}{4}[/tex]
Now, add [tex]\dfrac{1}{4}[/tex] in the expression to make it perfect square trinomial.
[tex]n^2+n+\dfrac{1}{4}[/tex]
[tex]\Rightarrow n^2+n+\left(\dfrac{1}{2}\right)^2[/tex]
[tex]\Rightarrow \left(n+\dfrac{1}{2}\right)^2[/tex] [tex]\because (a+b)^2=a^2+2ab+b^2[/tex]
Therefore, perfect square trinomial is [tex]n^2+n+\dfrac{1}{4}[/tex] and binomial squared is [tex]\left(n+\dfrac{1}{2}\right)^2[/tex].

Two fair dice are tossed and the number on each die is recorded, e.g. (3,2) indicates the first die had 3 and the second die had a 2. In total, there are 36 (equally likely) outcomes in the sample space. What is the probability the sum of the two dice is 7
Answer:
[tex]\dfrac{1}{6}[/tex]
Step-by-step explanation:
Given that two fair dice are tossed.
Total outcomes as we toss two dice are given as:
{
(1,1) (1,2) (1,3) (1,4) (1,5) (1,6)
(2,1) (2,2) (2,3) (2,4) (2,5) (2,6)
(3,1) (3,2) (3,3) (3,4) (3,5) (3,6)
(4,1) (4,2) (4,3) (4,4) (4,5) (4,6)
(5,1) (5,2) (5,3) (5,4) (5,5) (5,6)
(6,1) (6,2) (6,3) (6,4) (6,5) (6,6)
}
Where (a, b) represents a is the outcome of the die rolled for the 1st time and b is the outcome of 2nd toss of the die.
Total number of outcomes = 36
The outcomes with sum = 7 are :
{(1, 6), (2, 5), (3, 4) , (4, 3), (5, 2), (1, 6)}
Number of outcomes = 6
Probability of an event E is given as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
[tex]P(sum=7) = \dfrac{6}{36}\\\Rightarrow \bold{P(sum=7) = \dfrac{1}{6}}[/tex]

Benito embroiders and sells T-shirts. The graph shows his profit as a function of the number of shirts sold. After selling a certain number of shirts, Benito uses some earnings to buy more materials and then increases the price of the shirts. Which of the following is true? a. The domain of the function is {x | x is a real number greater than or equal to 0}. b. Benito increases the price after selling 50 shirts. c. The x-intercept represents the shirts he has to sell before making a profit. d. The y-intercept represents the cost of one T-shirt.
Answer:
a. The domain of the function is {x | x is a real number greater than or equal to 0}.
Step-by-step explanation:
The graph shows
1) the domain of the function {x | x is a real number greater than or equal to 0}
The domain of the function of the graph is obtained by the x - values which range from 0-11 . Thus they are equal or greater than zero.
2) the y- intercept shows the profit that is made by selling a certain number of shirts.
3) the x- intercept shows the number of shirts sold
4) Benito increases the price at least after the profit of $25 is made because we see from the graph that there is a loss of $10 if one shirt is sold separately and the dot on the eight appears around $ 25.
Only option a is true.
Graphs are used to show the relationship between related quantities.
From the given options, the true statement is:
c. The x-intercept represents the shirts he has to sell before making a profit.
From the given graph, we have the following observations.
1. The domain of the graph is [tex]x \ge 2[/tex]
The corresponding y-values are negative for x = 0 and 1.
Because the graph represents the profit function, no value of x must correspond to a negative y-value.
Hence, (a) is false
2. It is impossible to say that his price increases, after selling 50 shirts
The y values show profit from shirts; not the price of shirts
Hence, (b) is false
3. The x-intercept indicates when he'll make a profit
The graph crosses the x-axis at x= 2.
This means that, he has to sell at least 2 shirts, before making a profit.
Hence, (c) is true
4. The y-intercept is the cost of 1 shirt
The y values show profit from shirts; not the price of shirts
Hence, (d) is false
Based on the above analysis, we can conclude that (c) is true

The graph of a quadratic function with vertex (-3,2) is shown in the figure below . Find the domain and the range
Answer:
domain: all realsrange: y ≥ 2Step-by-step explanation:
The domain of any polynomial function, quadratics included, is "all reals."
The graph opens upward, so the y-value of the vertex is the minimum value of the range: y ≥ 2.
Two cyclists, 40 miles apart, start riding toward each other at the same time. One cycles 3 times as fast
as the other. If they meet 2
hours later, what is the speed (in mi/h) of the faster cyclist?
Answer:
15 mph
Step-by-step explanation:
The cyclists will cover distance at a rate proportional to their speed. So, the distance ratio is ...
faster cyclist distance : slower cyclist distance = 3 : 1
Then the faster cyclist covers 3 : (3+1) = 3/4 of the total distance, or (3/4)(40 mi) = 30 mi.
That distance took 2 hours for the faster cyclist, so the speed was ...
speed = distance/time = 30 mi/(2 h) = 15 mi/h

A store sells paint sets. Each paint set costs the same amount. During a sale, the store reduces the price of each paint set by $1.50. Logan spends
$13.47 on 3 paint sets at the sale price.
What was the price of I paint set before the sale?
Answer:
the price of I paint set before the sale was $5.99
Step-by-step explanation:
Selling price of 3 paint sets = $13.47
To get selling price of 1 set
we divide both LHS and RHS by 3
Selling price of 3/3 = 1 paint sets = $13.47/3 = $4.49
Thus, selling price of 1 paint set after sale is $4.49
Given that
the store reduces the price of each paint set by $1.50
Let the price before sale be x
selling price of 1 paint set after sale = price before sale - $1.50
$4.49 = $x - $.150
$x = $4.49 + $1.50 = $5.99
Thus, the price of I paint set before the sale was $5.99

Michael paid $16.40 for 20.5 centimeters of wire. Find the unit price in dollars per centimeter. If necessary round your answer to the nearest cent.
Answer:
$0.80
Step-by-step explanation:
$16.40 ÷ 20.5 = 0.80
You can check your work by doing :
20.5 cm of wire × $0.80 = $16.40
The unit price of the wire which Michael bought 20.5 cm for $16.40 is $0.8.
What is The Unit price?The price of a product offered in more or fewer than one unit is referred to as the unit price. The "unit pricing" of a food package informs you of the price per pound, quart, or another unit of weight or volume. Normally, it is displayed underneath the food on the shelf. The item price (total price) and unit price (unit price) for the food item are both displayed on the shelf tag. When shoppers are taught how to use unit price information in supermarkets, research reveals that they can save about 17–18%, but over time, this number decreases.
Given:
The price for the length of 20.5-centimeter wire, a = $16.40,
Calculate the price of 1 cm wire by dividing the total price by the length of the wire,
So unit price = 16.40 ÷ 20.5
Unit price = $0.8
Therefore, the unit price of the wire is $0.8.

Answer:
The side of the square is 15m
The side of the triangle is 20m
Step-by-step explanation:
P square = 4s where s is the side length
P triangle = 3 x where x is the side length
x = s+5
The perimeters are equal
4s = 3x
Replace x with s+5
4s = 3(s+5)
Distribute
4s = 3s+15
Subtract 3s from each side
4s-3s = 15
s = 15
The side of the square is 15
x =s+5
