Answer:
No solution
Step-by-step explanation:
You can solve this in a few ways. One way is to graph the equation, and the solution is the x-value of the point of intersection. Another way would be to factor, which is more difficult to complete with a square bigger than 2.
By graphing, you can see a parabola that never touches that x-axis, which means no solution.

-25 is an integer and a rational number.
What is number system?A system of writing numbers is known as a number system. It is the mathematical notation for consistently employing digits or other symbols to represent the numbers in a particular set. It represents the arithmetic and algebraic structure of the numbers and gives each number a distinct representation.Now,
Natural numbers are positive integers with a range of 1 to infinity; nevertheless, they do not include zero. -25 wouldn't be a natural number because it is a negative number.A group of numbers known as a whole number consists of all positive integers and 0. This wouldn't be a whole number because -25 isn't a positive number.Any real number that cannot be represented as the quotient of two integers is said to be irrational. Square roots of irrational numbers are also frequently seen. -25, however, is not a square root.Any number that can be expressed as a ratio, or a fraction, of two integers, is referred to be a rational number. Fractions, decimals, negative decimals, and other rational numbers are very prevalent. Since -25 can be represented as a ratio of two numbers. it is a rational number.A whole number that can be either positive, negative, or zero is known as an integer. As -25 is negative and a whole number( when positive), it is an integer.Hence, -25 is an integer and a rational number.

Carla wrote this number:815,247 travis wrote this number: 638.571 the digit 8 in carlas number represents how many times what the digit 8 represents in travis number?
Answers
The digit 8 in Carla’s number represents 10 times of what the digit 8 represents in Travis’ number.
The number written by Carla = 814,247
The number written by Travis = 683,571
The place value of digits starting from left is ones, ten's, hundreds, thousands, ten thousand, hundred thousand and so on.
As per this sequence of values, we can see that digit 8 in Carla's number is at hundred thousand place value. Also, digit 8 in Travis' number is at ten thousand place value. So, representing these place value in numeral form and finding the number of times one is greater than other.
Digit 8 in Carla's number: 100,000
Digit 8 in Travis' number: 10,000
Finding the answer -
Value = 100,000 ÷ 10,000
Cancelling common zeroes from numerator and denominator
Value = 10
Hence, digit 8 in Carla’s number represents 10 times of what the digit 8 represents in Travis’ number.

For example, in the fraction 8/7, 8 is the numerator and 7 is the denominator.
Step-by-step explanation: Like In this fraction 7/3, 7 is the numerator and 3 is the denominator. In the fraction 9/7, 9 is the numerator and 7 is the denominator.The value placed above the horizontal line in a fraction is called a numerator.

The number of hits A got is 186 hits.
A player's batting average is calculated by dividing the number of hits by the number of at-bats.
Player A batting average = 0.312
Number of at-bats A did = 596
We have to find the number of hits A got.
0.312 = Number of hits / 596
Number of hits = 0.312 x 596

To graph this line (or any line, actually) what you need to do is find two points on the line.
To do so, you need to evaluate the function.
If we use x = 0, then:
y = 3*0 - 2 = -2
So we have the point (0, -2)
If we use x = 1, then:

Step-by-step explanation:
You want the value of the expression 2f(-3)-f(4), given that f(x) = 3x²-x+ 5.
Function evaluationA function is evaluated by putting the argument where the variable is, and simplifying the result. Polynomials are often easier to evaluate if they are written in Horner form.
f(x) = 3x² -x +5
f(x) = (3x -1)x +5
The values we need are ...
f(-3) = (3(-3) -1)(-3) +5 = (-10)(-3) +5 = 35
f(4) = (3(4) -1)(4) +5 = (11)(4) +5 = 49
Then the expression of interest has the value ...
2f(-3) -f(4) = 2(35) -49 = 70 -49

The probability that a set of all bulbs work is 0.88.
What is called as the total probability?The total probability rule (also known as the Law of Total Probability) divides probability calculations into discrete steps.
It's used to calculate the probability of an event, A, once you don't know enough about A's probabilities to do so directly. Instead, you use a related event, B, to calculate the probability of A.Two events are considered independent if a occurrence of one does not affect the likelihood of occurrence of the other.Now, as per the question;
The total number of bulbs be 120 and each bulb is working as independent event.
The reliability of each bulb is 99.9% = 0.999
Let 'p' the probability the bulb will work.
The probability that all will work = p¹²⁰
The probability that all will work = (0.999)¹²⁰ = 0.886

Katy invests a total of $10,500 in two accounts paying 11% and 5% simple interest, respectively. How much was invested in each account if, after one year, the total interest was $945.00.
A) Enter an equation that uses the information as it is given that can be used to solve this problem. Use x as your variable to represent the amount of money invested in the account paying 11% simple interest.
Equation:___________
B) The answers are:
$____ was invested at 11% and
$____was invested at 5%
Answers
Answer:
Equation: 0.11x + 0.05(10500 - x) = 945
$7000 was invested at 11% and
$3,500 was invested at 5%
Step-by-step explanation:
There are two equations needed
Let x = amount of money invested at 11%
11% = 11/100 = 0.11 in decimal
Interest at 11% for 1 year = 0.11x
Amount of money invested at 5% interest. 5% = 0.05
= 10500 - amount invested at 11%= 10500 - x
Interest from this amount after 1 year = 0.05(10500 - x)
Total of these two = 945
So 0.11x + 0.05(10500 - x) = 945
The equation based on the information as it is given:
0.11x + 0.05(10500 - x) = 945
We know the total interest obtained was $945 so we have the equation
0.11x + 0.05(10500- 5x) = 945
Simplify
0.11x + (525 - 0.05x) = 945
==>0.11x + 525 - 0.05x = 945
==> 0.06x = 945 - 525
==> 0.06x = 420
==> x = 420/0/06 = $7000
Amount invested at 11% interest is $7,000
Amount invested at 5% interest = 10,500 - 7,000 = $3,500
