Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

The value of a boat is $23,400. It loses 10% of its value every year. Find the approximate monthly percent decrease in value. Round your answer to the nearest hundredth of a percent.
Answer:
Value of boat = $23,400
Loss of value by boat per year = 8%
To find: - Monthly percent decrease in value of boat.
Solution: - Decrease of value per year = 8% of $23,400 = $1,872. Monthly decrease in value = $1,872/12 = $156. Monthly percentage decrease = ($156/$23,400) * 100 = 0.6667 or 0.67 (rounded to nearest hundredth)

А с
A) 12
C) 8
B) 10
D) 2
Answer:
B) 10
Step-by-step explanation:
Exterior angle property: Exterior angle equals the sum of opposite interior angles.
12x + 10 = -10 + 7x + 70 {Subtract 10 from both sides}
12x = -10 + 7x + 70 - 10
12x = -10 + 70 - 10 + 7x {Combine like terms}
12x = 50 + 7x {Subtract 7x from both sides}
12x - 7x = 50
5x = 50 {Divide both sides by 5}
x = 50/5
x = 10

Which equation, solved for x, is equivalent to y-h=x-g/k
A.x=k(y-h)-g
B.x=ky -h+g
C.x=k(y-h) +9
D.x = ky-h-9
Answer:
a
Step-by-step explanation:
The equation equivalent to the given equation y-h=x-g/k is .x=k(y-h) +g. The correct option is C.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is y-h=x-g/k. The equation will be solved as,
y-h = ( x-g ) / k
k( y-h ) = x - g
k( y-h ) + g = x
Therefore, the equation equivalent to the given equation y-h=x-g/k is .x=k(y-h) +g. The correct option is C.

Answer:
189/230
Step-by-step explanation:
Convert these to fractions first, because then it would be easier to calculate.
3 39/50 divided by 4 3/5
Turn the fractions into improper fractions:
189/50 divided by 23/5 = 189/50 times the reciprocal of 23/5
So we have:
189/50 x 5/23 = 945/1150 = 189/230

The sum of two numbers is __________ greater than either number.
a) Always
b) Sometimes
c) Never
d) Not enough information
The correct answer is b) Sometimes.
Given that a statement,
"The sum of two numbers is __________ greater than either number."
We need to fill the blank from the options provided.
The sum of two numbers can be greater than either number depending on the specific values of the numbers.
Let's consider some examples:
Example 1: If we have two positive numbers, such as 3 and 4, their sum (3 + 4 = 7) is greater than either number individually.
Example 2: If we have one positive number and one negative number, such as 5 and -8, their sum (5 + (-8) = -3) is greater than -8 but less than 5.
Example 3: However, if we have two negative numbers, such as -2 and -4, their sum (-2 + (-4) = -6) is not greater than either number individually.
Therefore, since the statement holds true in some cases but not in others, the correct answer is sometimes (b).

Sandeep used 8 litres of fuel to travel 76 miles.
He wants to know how many miles he will be able to travel with 22 litres of fuel.
He assumes that the distance travelled and the amount of fuel used are directly proportional.
How many miles can he drive with 22 litres of fuel?
Answer:
I got, when calculated, 209 miles. (It may be wrong)
Step-by-step explanation:
First, I calculated how many miles can Sandeep travel with 1L, therefore I divided 76 miles by 8L and got 9.5 miles on 1L.
Then I multiplied 9.2 miles by 22L and got 209 miles.
This may be wrong but if anyone else is able to work it out much appreciated if it's correct.. Your most welcome!
