If five less than y is six more than x + 1, then by how
much is x less than y?
Answer:
12 more
Step-by-step explanation:
y-5= 6+ (x+1)
5+6+1=12
x is 12 less than y.
Five less than y is six more than x + 1,
y - 5= 6 + (x + 1)
5 + 6 + 1 = 12.

The x-intercepts are the same. 4. The sum has one y-intercept and the product has two x-intercepts. 5. Both functions decrease for x > 2
Answer:
Step-by-step explanation:
B) the sum is linear and the product is quadratic
D) the sum has one y-intercept and the product has two x-intercepts
The sum is linear and the product is quadratic and The sum has one y-intercept and the product has two x-intercepts are two statements which compare the sum and product
What is Equation?Two or more expressions with an Equal sign is called as Equation.
We need to find the statements which correctly compare the sum and product
The given statements are
1. Both functions have a constant rate of change.
2. The sum is linear and the product is quadratic.
3. The x-intercepts are the same.
4. The sum has one y-intercept and the product has two x-intercepts.
5. Both functions decrease for x > 2
A linear function simply means a function that represents a straight line on the coordinate plane.
In this case, the sum is linear and the product is quadratic while the sum has one y-intercept and the product has two x-intercepts.
Hence, the sum is linear and the product is quadratic and The sum has one y-intercept and the product has two x-intercepts are two statements which compare the sum and product

Customer arrivals at a bank are random and independent; the probability of an arrival in any one-minute period is the same as the probability of an arrival in any other one-minute period.
A. What is the probability of exactly three arrivals in a one-minute period?
B. What is the probability of at least three arrivals in a one-minute period?
Answer:
0.2240418 ; 0.57681
Step-by-step explanation:
Given the information above :
A) What is the probability of exactly three arrivals in a one-minute period?
Using poisson probability function :
p(x ; m) = [(m^x) * (e^-m)] / x!
Here, m = mean = 3, x = 3
P(3 ; 3) = [(3^3) * (e^-3)] / 3!
P(3;3) = [27 * 0.0497870] / 6
= 1.3442508 / 6
= 0.2240418
B) What is the probability of at least three arrivals in a one-minute period?
Atleast 3 arrivals
X >= 3 = 1 - [p(0) + p(1) + p(2)]
P(0 ; 3) = [(3^0) * (e^-3)] / 0! = (1 * 0.0497870) / 1 = 0.0497870
P(1 ; 3) = [(3^1) * (e^-3)] / 1! = (3 * 0.0497870) / 1 = 0.1493612
P(2 ; 3) = [(3^2) * (e^-3)] / 2! = (9 * 0.0497870) / 2 = 0.2240418
1 - [0.0497870 + 0.1493612 + 0.2240418]
1 - 0.42319 = 0.57681
A book has 89 pages, but the page numbers are printed incorrectly. Every third page number has been omitted, so that the pages are numbered 1,2,4,5,7,8,... and so on. What is the number on the last printed page?
Answer:
89
Step-by-step explanation:
There are only 30 pages but last page number is 89.
The last page of the book would be with the number 89. For details, check the calculations below.
Number SystemThe number system is characterized as the arrangement or sequence in which the numbers are arranged in a mathematical order beginning from 0 in whole numbers.
In the given situation,
We know that,
Total pages available in the book = 30
And every third page is omitted from the book due to misprinting of the page numbers.
If we divided 90/3 = 30 pages are there. Hence, the last page would be 89 itself.
Thus, the above response is correct.

a rectangular shape waiting room has an area 120ft and a perimeter of 44 ft.what are the dimensions?
Answer: W * L = 120
2W + 2L = 44
2W = 44 - 2L
W = 22 - L
(22-L) * L = 120
22L - L² = 120
L² - 22L = -120
L² - 22L + 121 = 121 - 120
(L - 11)² = 1
L - 11 = ±1
L = 11 ± 1
L = 10 or 12

Why is√5 irrational?
A.)because it is less than one
B.)because it has no opposite
C.)because all square roots are irrational
D.)because it cannot be expressed as a ratio of integers
Answer: The expression x(x + 1) is even for any integer x (since either x or x + 1 is even). So this says that 5 × even + 1 = even, or odd = even. Since there is no integer that is both even and odd, we have reached a contradiction and √5 is irrational. So the answer would be D.) because it cannot be expressed as a ratio of integers
According to a November 2019 report by CNN, the startup company Heliogen has devised a high-heat solar oven that can be used to create concrete and steel without the use of fossil fuels. Currently, the creation of these materials produces 7% of the world's carbon emissions from fossil fuels. If the world's total carbon emissions in 2018 was 37.1 billion tons, how much of that carbon came from the creation of these building materials? Give your answer in billions of tons. Round to two decimal places.

what is the product?
x^2 -16 • x^3 - 2x^2 + x———— ——————–—
2x +8 x^2 +3x -4
Answer:
A) x(x-4)(x-1)/2(x+4)
Step-by-step explanation:
(x²-16)/(2x+8) * (x³-2x²+x)/(x²+3x-4)
factor
(x+4)(x-4)/2(x+4) * x(x-1)(x-1)/(x+4)(x-1)
You can take out both (x+4) from the first side, and both (x-1) on the second side. Then you’re left with:
(x-4)/2 * x(x-1)/(x+4)
which equal
x(x-4)(x-1)/2(x+4)
which is A.

for a medical office complex. There are 36 people on the payroll. Eight people earn $10 per hour, eleven people earn $15 per hour, four people earn $18 per hour, six people earn $21 per hour, and seven people earn $26 per hour. If everyone works 40 hours per week, what is the total amount of money needed for the payroll each week?
Answer:
$25,000
Step-by-step explanation:
8 x $10 = 80 x 40 = $3,200
11 x $15 = 165 x 40 = $6,600
4 x $18 = 72 x 40 = $2,880
6 x $21 = 126 x 40 = $5,040
7 x $26 = 182 x 40 = $7,280
3200 + 6600 + 2880 + 5040 + 7280 = $25,000

identify the degree of the polynomial x^2y+5xy^3-7y^2+2
We have three parts of the equation with a power:
x^2y, 5xy^3, and 7y^2
We can find the degree of each by the following:
x^2y; 2 + 1 = 3
5xy^3; 1 + 3 = 4
7y^2; 2
Therefore, the highest degree is 4.

If B is the midpoint of AC. AB = 4v and AC = 5v + 24. what is BC?
Answer:
v+24
Step-by-step explanation:
I first drew a line with A in one side and C in the other side. Then, I put B in the middle, as it is the midpoint. Under AB, I put 4v, and under AC, I put 5v+24. To get BC, you must subtract 5v+24 and 4v. I did 5v+24-4v. All I really had to do was subtract 4v from 5v which gave me v, since I can only subtract like-term numbers. Anyway, after that, I got v+24.

On a coordinate plane, a line goes through points (0, 1) and (3, negative 1). Consider the graph of the line. Using the rise/run counting method, the slope of the line is .
Answer: The slope of the line is -2/3.
Step-by-step explanation:
How I think of it is that on the y plane on a graph, going from positive 1 to negative 1 you need to move down 2 places and thats the "rise" part of rise over run eventhough you moved down. Then on the x plane, going from 0 to 3 you need to move 3 spaces to the right on the graph and thats the "run" part of rise over run because you can either move left or right. Rise over run can also be thought of as change in y over change in x which means that since i went down 2 places on the y, the change in y was 2 and since we moved 3 places over on the x plane the change in x whould be 3. Since we move down and then to the right on the graph, the line being created would be negative, so you final answer for the slope is -2/3!
