Step-by-step explanation:
The first number is -2 and the second number is 1
Answer:
The first number is -2 and the second number is 1.
Step-by-step explanation:
2n + 3s = -1
(n + 4s = 2)-2 Multiply by -2 to cancel the n
2n + 3s = -1
-2n - 8s = -4 Add these equations together
-5s = -5 Divide both sides by -5
s = 1
Plug this into the first equation to find the value of n
2n + 3(1) = -1 Multiply
2n + 3 = -1
- 3 - 3 Subtract 3 from both sides
2n = -4 Divide both sides by 2
n = -2
Find positive integer x, if 1+2+3 +...+x=120.
Answer:

[tex]S_{n} = \frac{n(n + 1)}{2}[/tex]
According to the question,
Given positive integers,
[tex]1 + 2 + 3 + ......... + x =120[/tex]
Substitute the value in the formula to get sum of positive integers,
[tex]\frac{x(x+ 1)}{2}=120\\\\\implies x^{2} +x =240\\\\\implies x^{2} + x-240 =0\\\\\implies x^{2} +16x-15x -240=0\\\\\implies x (x+16) -15 (x+16) =0\\\\\implies (x+ 16) (x-15) =0\\\\\implies x = -16 or x =15[/tex]
[tex]'x'[/tex] is a positive integer. [tex]x=-16[/tex] is not possible.
Hence, Value of positive integer [tex]x[/tex] is equals to [tex]15[/tex].

A. It is the graph of y= x translated 13 units up.
OB.
It is the graph of y = x translated 13 units to the right.
C.
It is the graph of y= x translated 13 units to the left.
• D. It is the graph of y = x where the slope is decreased by 13.
Answer:
D
Step-by-step explanation:
Refer to picture.
When graph of y = x is transformed to y = x - 13,
U can visualise it by drawing the before and after transformed graphs to compare in order to deduce the answer.
From the picture, you will realise that when x is unchanged, I'm this case I'm using points x=0 and x=13, the value of the y coordinate in the transformed graph (y = x-13) actually decreased by 13 units as compared to the original graph of y=x.
Hence the graph actually got translated 13 units in the direction of negative y axis which is option D
As per the translation of a graph, the given graph y= x is translated 13 units to the right.
What is the translation of a graph?"The translation of a graph is its rigid movement, vertically or horizontally."
The given equation of the graph is: y = x.
The equation of the translated graph is: y = x - 13.
We know, the translation of a graph from y = f(x) to y = f(x - a) is translating the graph to the right by 'a' units.
Therefore, the given graph y= x is translated 13 units to the right.

cost for each chocolate gift basket?
A) $20 B) $25 C) $30 D) $54
PLS HELP ME ASAP!
Answer: The cost for each chocolate gift basket is b)$25.
Step-by-step explanation:
Hi, the correct equations are:
6x + 5y =300
3x + 7y = 285
So, if we multiply the second equation by 2, and subtract the first equation to the second equation:
6x +14 y= 570
-
6x +5y =300
_________
9y = 270
Solving for y:
y = 270/9
y = 30
Substituting y=30 on any equation:
6x + 5y =300
6x + 5(30) =300
Solving for x (cost for each chocolate gift basket)
6x+150 =300
6x =300-150
6x = 150
x =150/6
x = $25

x=4
y=0
y=4
Answer:
(C)y=0
Step-by-step explanation:
An exponential function of the form [tex]f(x) = a (b^x) + c[/tex] always has a horizontal asymptote at y = c.
Given our function [tex]y=4^x[/tex]
Comparing with the form, [tex]f(x) = a (b^x) + c[/tex], we observe that c=0.
Therefore, the exponential function has an asymptote at y=0.

Jason and his brother each have the equal probability of being randomly selected to wash dishes after dinner. Jason wants to simulate the probability that more than 4 evenings will go by without him having to wash the dishes after dinner. He decides to conduct a simulation by flipping a quarter, with heads representing an evening where he washes dishes after dinner and tails representing an evening of not doing dishes after dinner. He keeps flipping until he flips heads and records the number of flips that were needed. For example, if two flips are needed to get heads, this indicates that he washes dishes on the second evening. He repeats this 50 times and records the data on the table below Number of flips until getting heads: 1,2,3,4,5,6,7,8 frequency: 21,18,4,4,2,0,0,1 Based on the results of the simulation, what is the probability that more than 4 evenings will go by without Jason having to wash dishes after dinner? [blank] %
Answer:
The probability that more than 4 evenings will go by without Jason having to wash dishes after dinner is 0.06.
Step-by-step explanation:
We are given that Jason wants to simulate the probability that more than 4 evenings will go by without him having to wash the dishes after dinner.
He repeats this 50 times and records the data on the table below;
Number of flips until getting heads Frequency
1 21
2 18
3 4
4 4
5 2
6 0
7 0
8 1
Total 50
Now, we have to find the probability that more than 4 evenings will go by without Jason having to wash dishes after dinner.
This will happen only when the Number of flips until getting heads is 5, 6, 7 or 8 as only then Jason will have more than 4 evenings go by without washing dishes after dinner.
So, required probability = [tex]\frac{2}{50}+\frac{0}{50}+\frac{0}{50}+\frac{1}{50}[/tex]
= [tex]\frac{3}{50}[/tex] = 0.06

Simplify i^12
A. -1
B. -i
C. i
D. 1
Answer:
D
Step-by-step explanation:
Answer:
D. 1.
Step-by-step explanation:
We know that the powers of the imaginary constant, i, follow a certain pattern.
i^1 = i, i^2 = -1, i^3 = -i, i^4 = 1.
Every 4 powers, the result cycles back to the original i. This is because there are only 4 unique digits that result from raising i to various powers.
To figure a higher power, such as 12, we need to take the remainder of the power when divided by 4 (the amount of unique answers), to simplify it to the original 4 powers.
So when you have i^12 power, the remainder is 0. This is because 4 is a factor of 12. As a result, we can simplify this to i^8, and therefore i^4, which equals 1.
I hope this helps!
What’s the difference between sine and cosine
Answer:
Sine and cosine — a.k.a., sin(θ) and cos(θ) — are functions revealing the shape of a right triangle. Looking out from a vertex with angle θ, sin(θ) is the ratio of the opposite side to the hypotenuse , while cos(θ) is the ratio of the adjacent side to the hypotenuse .
Step-by-step explanation:
Answer:
A.k.a., sin(total), cos(total) are functions that indicate the direction a triangle is right. Speaking from an angle point, sin(f) is an opposite of a hypotenous ratio, while cos(f) is the equivalent to the hypotenuse ratios

The drama club is selling tickets to their play to raise money for the show's expenses.
Each student ticket sells for $4.50 and each adult ticket sells for $8. The auditorium
can hold no more than 84 people. The drama club must make at least $560 from
ticket sales to cover the show's costs. If 29 student tickets were sold, determine all
possible values for the number of adult tickets that the drama club must sell in order
to meet the show's expenses. Your answer should be a comma separated list of values.
If there are no possible solutions, submit an empty answer.
Answer:
The minimum number of adult tickets required to be sold = 54
Step-by-step explanation:
Hello,
In this question, we have several variables which might confuse us here, so I'll have to break it down bit by bit.
The drama club must make a sale of $560 so as to cover cost for the event.
The seat capacity of the hall = 84
Cost of tickets for adult = $8
Cost of tickets for students = $4.50
Total number of students sold = 29
Let the number of adult ticket required = x.
(4.50 × 29) + (8 × x) = 560
130.5 + 8x = 560
8x = 560 - 130.5
8x = 429.5
Divide both sides by 8
X = 429.5 / 8
X = 53.6 approximately 54.
Minimum required number of adult tickets to be sold is 54.
(29 × 4.50) + (54 × 8) = $130.5 + $432 = $562.5

Rectangle LMNO has vertices L (–4, 6), M (–1, 6), N (–1, 2), and O (–4, 2). Suppose you reflect this rectangle across the x-axis, and then translate it up two units. What are the corresponding vertices of L′′M′′ N′′O′′? Question 11 options: A) L′′ (–4, –4), M′′ (–1, –4), N′′ (–1, 0), O′′ (–4, 0) B) L′′ (4, –4), M′′ (1, –4), N′′ (1, 0), O′′ (4, 0) C) L′′ (–4, 8), M′′ (–1, 8), N′′ (–1, 4), O′′ (–4, 4) D) L′′ (–4, –8), M′′ (–1, –8), N′′ (–1, –4), O′′ (–4, –4)
Answer:
The correct option is:
A) L'' (-4 , -4) , M'' (-1 , -4) , N'' ( -1 , 0) , O'' (-4 , 0)
Step-by-step explanation:
The following are the vertices of a rectangle LMNO
L (-4 , 6)
M (-1 , 6)
N (-1 , 2)
O (-4 , 2)
First we have to reflect it across x-axis
When we reflect a shape across x-axis, the x components of the points remain the same while y components change their signs. After reflection:
L' (-4 , -6)
M' (-1 , -6)
N' ( -1 , -2)
O' (-4 , -2)
After we translate it up by two units, we add +2 to y components of each reflected point.
L'' (-4 , -4)
M'' (-1 , -4)
N'' ( -1 , 0)
O'' (-4 , 0)
Hence, the correct option is A

Which is the equation for a sphere with the center (8,-6,6) and radius 6?
Answer:
(x - 8)² + (y+6)² + (z-6)²= 36
Step-by-step explanation:
To find the equation for a sphere with the center (8,-6,6) and radius 6, we will follow the steps below;
first write down the standard equation of a sphere:
(x - h)² + (y-k)² + (z-l)²= R²
where h, k and l are the center and R is the radius
From the question given, h = 8, k =-6 l=6 and R=6
we can now substitute the values into the formula
(x - h)² + (y-k)² + (z-l)²= R²
(x - 8)² + (y+6)² + (z-6)²= 6²
(x - 8)² + (y+6)² + (z-6)²= 36
Therefore, the equation for a sphere with the center (8,-6,6) and radius 6 is
(x - 8)² + (y+6)² + (z-6)²= 36
