the sum of two consecutive integers is 299. find the integers.
I HOPE THE ABOVE INFORMATION WILL HELP YOU.
THANK YOU.
TEDDYLOVER
Since the sum of two consecutive integers is 299, the integers are 149 and 150
What are integers?Integers are posiive or negative whole numbers.
Since the sum of two consecutive integers is 299. To find the integers., we proceed as follows.
Since the sum of two consecutive integers is 299.
Let the two consecutive integers be n and n + 1.
Since the sum of two consecutive integers is 299, we have that
n + n + 1 = 299
Adding like terms, we have that
n + n + 1 = 299
2n + 1 = 299
Subtracting 1 from both sides of the equation, we have that
2n + 1 = 299
2n + 1 - 1 = 299 - 1
2n + 0 = 298
2n = 298
Dividing both sides of the equation by 2, we have that
2n = 298
n = 298/2
n = 149
So, n + 1 = 149 + 1 = 150
So, the integers are 149 and 150

wHAT IS THE DOMAIN OF THE FUNCTION fx=(x+1)/(x^2 +2x-3)
Answer:
Domain : R−{−1,3}
Range: R
Step-by-step explanation:
Equate the denominator(x2−2x−3) to zero, then solve the equation for x
→x2−2x−3=0
→x=−(−2)±√(−2)2−4⋅(1)⋅(−3)2⋅1
→x=1±2
⇒x=−1 and x=3
This means that, when x=−1 or 3, we have the x2−2x−3=0
Implying that f(x)=x0 which is undefined.
Hence, the domain is all real numbers except −1
and 3
Also written as Df=(−∞,−1)∪(−1,3)∪(3,+∞)

four times the sum of a number and 7 is 44 less than the number
Answer:
The number is 17.
Step-by-step explanation:
Let x be the unknown number.
4 times the sum of a number plus 7 would be
4x + 7
44 less than the unknown number (x) would be
x - 44
Now we connect everything.
4x + 7 = x - 44
4x - x = -44 - 7
3x = -51
x = -17
The algebraic representation of the expression is 4(x + 7) = x - 44
How to determine the algebraic representation of the expressionFrom the question, we have the following parameters that can be used in our computation:
four times the sum of a number and 7 is 44 less than the number
By definiton:
Sum means plus
Less than means minus
Using the above as a guide, we have the following:
4 * (x + 7) = x - 44
So, we have
4(x + 7) = x - 44

If f(x - 1) = 2x + 3 for all values of x, what is the
value of f(-3)?
Answer:
-1
Step-by-step explanation:
F(x - 1) = 2x + 3.
Rewrite the right side (2x + 3)
F(x - 1) = 2[ x ] + 3
F(x - 1) = 2[ x - 1 + 1 ] + 3 = 2 [ (x - 1) + 1 ] + 3
= 2 (x - 1) + 2 + 3
= 2(x - 1) + 5
replace "x - 1" with "-3" :
F(-3) = 2(-3) + 5 = -1

What is the distance between two points with coordinates (32,12,5) and (20,3,13) in space?
The distance between two points with the given coordinates in space is;
Distance = 17 units
We are given the coordinates;
(32, 12, 5)
(20, 3, 13)
Formula for the distance between two points that have (x, y, z) coordinates is;d = √((x₂ - x₁)² + (y₂ - y₁)² + (z₂ - z₁)²)
From the equation given to us, we can see that;
x₁ = 32
x₂ = 20
y₁ = 12
y₂ = 3
z₁ = 5
z₂ = 13
Using the formula for the distance, we have;d = √((20 - 32)² + (3 - 12)² + (13 - 5)²)
d = √(144 + 81 + 64)
d = √289
d = 17
Thus, the distance between the two points is 17 units

In a statewide lottery, one can buy a ticket for $1. With probability .0000001, one wins a million dollars ($1,000,000), and with probability .9999999 one wins nothing ($0). Let Y denote the winnings from buying one ticket. Construct the probability distribution for Y. Show that the mean of the distribution equals .10, corresponding to an expected return of 10 cents for the dollar paid.
Using the expected value, it is found that the mean of the distribution equals $0.1.
The expected value, which is the mean of the distribution, is given by each outcome multiplied by it's probability.
The probabilities of each outcome are:
.0000001 probability of earning $1,000,000..9999999 probability of earning $0.Thus, the mean is given by:
[tex]E(Y) = 0.0000001(1000000) + 0.9999999(0) = 0.1[/tex]
Thus showing that the expected value is $0.1.
