Drag and drop the fractions to order them from least to greatest. -3/7 1/4 -4/5 2/3
Answer:
-4/5, -3/7, 1/4, 2/3
Step-by-step explanation:
The last one is the greatest as a positive but because it's both the greatest positive but a negative it is the smallest. Since 2/3 is closest to 1 and is positive it would be the greatest. -3/7 is a smaller value than 1/4 as it's closer to 0 than 1/4 is.

Determine the largest integer value x can have the inequality below. 3(2x - 5) - 2 < 2x + 4 + x
Step-by-step explanation:
First you will have to deal with the bracket by multiplying the numbers in it by 3.Group into like terms.divide both sides by the coefficient of x.For a quadratic in standard form f (x) = ax² + bx +e with
vertex (h,k), determine the indicated values.
For a general quadratic equation, we want to find the equations for the vertex (h, k).
The values of the vertex are:
h = -b/(2*a) k = f(h) = b^2/(4a) - b^2/(2a) + cWe start with the general quadratic equation:
f(x) = a*x^2 + b*x + c
To find the x-value of the vertex (h in this case) we need to find the zero of the first derivate of f(x) (because the vertex is a minimum/maximum of the function).
We have:
f'(x) = 2*a*x + b
We solve:
f'(h) = 0 = 2*a*h + b
-b/(2*a) = h
So we just found the value of h.
To find the value of k, the y-value of the vertex, we need to evaluate the function in the x-value of the vertex, we will get:
k = f(h) = a*( -b/(2*a))^2 + b*( -b/(2*a)) + c
k = b^2/(4a) - b^2/(2a) + c
Then, concluding, we have:
h = -b/(2*a) k = f(h) = b^2/(4a) - b^2/(2a) + cIf you want to learn more, you can read:

Noreen can walk 1/3 of a mile in 12 minutes what is her average speed in miles per hour. (this is multiple choice)
A. 36 miles per hour
B. 12 miles per hour
C. 1/4 a mile per hour
D. 1 2/3 miles and hour
Step-by-step explanation:
1/3 mile in 12 minutes (=1/5 of an hour).
so, the speed (ratio of distance/time) is
1/3 mile / 12 minutes
the speed in mph is the converted ratio, where the denominator (bottom) is turned into 1 (hour).
what do I need to multiply 12 minutes with to get 1 hour ?
the same to multiply 1/5 with to get 1 : 5
to keep the overall value of the ratio the same I need to multiply both parts (top and bottom) of the fraction with the same value.
therefore,
1/3 / 12 × 5/5 = (1/3 × 5) / (12×5) = 5/3 / 60
so, the speed in mph is
5/3 miles / 60 minutes = 5/3 miles / 1 hour = 5/3 mph = 1 2/3 mph
D is the right answer.
when 4a - a x 3a + 7a is simplified it is equivalent to?
Answer: -3a^2 + 11a
Step-by-step explanation:
4a - (a x 3a) + 7a - Multiply first to get 4a - 3a^2 + 7a
4a - 3a^2 + 7a - Add like terms (a terms) to get -3a^2 + 11a
So the answer in -3a^2 + 11a

determine whether each pair of ratios are equivalent ratios.
1. 8/9, 72/81
2. 3/14, 21/98
3. 12/17, 50/85
Answer:
1. Equivalent
2. Equivalent
3. Not equivalent
Step-by-step explanation:
So basically for all of them you need to find a multiple for the numerator of the first fraction to see if it equals the numerator of the second fraction, and same goes for denominator.
For the first one, 8*9 is 72, and you must multiply the denominator with the same number you multiplied the numerator with, so 9*9 is 81, so it is equivalent.

Leonard owns a business earning $37,800 in profits. These profits are appreciating at about 2.3% each year. What are Leonard's profits after eight years? (2 points)
$38,383.50
$45,341.60
$31,379.67
$44,755.20
Answer:
B. $45341.60Step-by-step explanation:
Given:
Initial profit = $37800Rate of appreciation = 2.3% per yearThe equation for this:
[tex]P(t) = 37800*(1 + 0.023)^t = 37800*1.023^t[/tex]Find the value of P(8):
[tex]P(8) = 37800*1.023^8 = 45341.60[/tex]Correct choice is B
Which expression is equivalent to (2x^4+8x^3-25x^2-6x+14)÷(x+6)

(2). 2x^3-4x^2-x+14
(3). 2x^3-4x^2-x + (14/(x+6))
(4). 2x^3-4x^2-x
Answer:
Here is your Answer
(3.) 2x^3-4x^2-x + (14/(x+6))
Step-by-step explanation:
The expression for the division of polynomials is obtained as (2x³- 4x²- x) + 14/(x + 6).
What is remainder theorem for polynomials?The remainder theorem states that that when a polynomial p(x) is divided by another polynomial x + a, then the remainder obtained is given as the value of the polynomial at x = -a which is written as p(-a).
The given problem can be solved by remainder theorem as follows,
Suppose p(x) = 2x⁴ + 8x³- 25x²- 6x + 14.
Now, when p(x) is divided by x + 6, the remainder is given as,
p(-6) = 2 × -6⁴ + 8 × -6³ - 25 × -6² - 6 × -6 + 14
⇒ p(-6) = 14
Thus, by division lemma the following equation can be written as,
2x⁴ + 8x³- 25x²- 6x + 14 = (x + 6)(2x³- 4x²- x) + 14
⇒ (2x⁴ + 8x³- 25x²- 6x + 14) ÷ (x + 6) = (2x³- 4x²- x) + 14/(x + 6)
Hence, the equivalent expression is given as (2x³- 4x²- x) + 14/(x + 6).

Answer:
Step-by-step explanation:
[tex]\frac{5+p}{9} <-1\\5+p<-9\\p<-9-5\\p<-14[/tex]
I need an explanation on how to do this one
ok!
to find mean, add all of the numbers, and divide that by how many numbers you have.
for example:
number 7 on your paper (8,9,10,15,28)
add those numbers together to get: 70
then divide 70 by 5 (since that's how many numbers there are in the problem) to get: 14
to get median write out all the numbers from least to greatest like you've done and find the middle number by marking off a number from the side each time then you will get: 10
to find mode you just write the number that appears the most. since there are no repeating numbers in your problem, theres no mode.
to find range you subtract the smallest number from the largest number in the problem.
so in your case, it would be 28-8
your range would be: 20
