The simplified form would be 338√x -72√2y.

If a fraction's top and bottom share only one additional common factor, it is said to be in its simplest form. In other words, the top and bottom cannot be divided further and remain full numbers.

The simplest form is also referred to as "lowest words."

the given expression is :

2(4√16x) - 2(4√2y) + 34√81x - 4(4√32y)

⇒ 8(√16x) - 8(√2y) + 34√81x - 16√32y  

⇒8×4√x - 8√2y + 34×9√x - 16√16×2y     [∵ √16 = 4 and √81 = 9]

⇒32√x - 8√2y + 306√x - 16×4√2y

⇒(32√x + 306√x) - 8√2y  - 16×4√2y      

⇒338√x -72√2y

By using algebra (5, 4) is not a solution of the inequality.

Boundary does not contain in the given graph this is the error was made when graphed.

What is inequality?

In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.

Consider, the given inequality

x + 2y ≤ 12

Here the inequality contain ≤ .

Since, if there is ≤  sign then graph must contain boundary line.

The boundary line is solid line need to use in the graph.

But in the given graph the boundary line is dotted.

Boundary does not contain in the graph.

Hence, this is the error was made when graphed.

Also from graph we can see that the point (5, 4) is not contain in the graph.

Hence, (5, 4) is not a solution of the inequality.

Now prove by using algebra.

Plug x = 5, y = 4 in the given inequality

⇒  5 + 2(4) ≤ 12

         5 + 8 ≤  12

             13 ≤  12

It is not possible that 13 ≤  12.

Hence, (5, 4) is not a solution of the inequality.

Answer:

two or four

Step-by-step explanation:

Any degree-X polynomial can have up to 8 zeros (some of them can have multiciplity higher than 1).

The polynomial can be written as:

f(x) = (x-a)(x-b)(x-c)(x-d)(x-e)(x-f)(x-g)(x-h)

and we're already told that there are 2 x-intercepts, one with multiplicity 1. Let's assign those x-intercepts a and b=c=d (multiplicity 3).

We're left with (x-e)(x-f)(x-g)(x-h), where e, f, g and h need to be non-real complex numbers (otherwise they'd provide x-intercepts).

The complex zeros (more accurate term than imaginary) must come in pairs - if a number c is a zero of the function, its conjugate is a zero too. That means that we need to have an even number of complex zeros.

We can either have 4 distinct complex zeros, or 2 complex zeros, each with multiplicity of 2.

Based on the definition of similar quadrilaterals, the measure of side MN is: 14.1 units.

If two quadrilaterals are similar to each other, then the measure of their corresponding sides will have a ratio that is equal. This means they will have proportional side measures.

Since we are told that quadrilaterals GHIJ and KLMN are similar to each other, then their corresponding sides will have measures that are proportional to each other.

Therefore:

IJ/MN = GJ/KN

IJ = 35

MN = ?

GJ = 52

KN = 21

Substitute:

35/MN = 52/21

Cross multiply:

MN(52) = (35)(21)

MN(52) = 735

MN = 735/52

MN = 14.1 units

The graph is given below.

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

y = 1.5x - 2

We can have the following coordinates on the graph.

x = 1, y = 1.5 - 2 = -0.5

(1, -0.5)

x = 2, y = 3 - 2 = 1

(2, 1)

x = 3, y = 4.5 - 2 = 2.5

(3, 2.5)

x = 4, y = 6 - 2 = 4

The equation of line r which is parallel to line q and passes through point (5,-4) is y = (-3/5)x - 1.

The slope-intercept form is expressed as;

y  = mx + b

The point-slope formula is expressed as

y - y₁ = m( x - x₁ )

Given the data in the question;

First, determine the slope of the line q using the slope intercept-form.

y = mx + b

3x + 5y = 10

5y = -3x + 10

y = (-3/5)x + 10/5

y = (-3/5)x + 2

Hence;

Slope of line q m = -3/5

Since, line r is parallel to line q, they both have the same slope.

Therefore, slope of line r will be m  = -3/5

Now, plug the point  (5,-4) and and slope m = -3/5 into the point slope formula and solve for y.

y - y₁ = m( x - x₁ )

y - (-4) = (-3/5)( x - 5 )

y + 4 = (-3/5)x + 3

y = (-3/5)x + 3 - 4

y = (-3/5)x - 1

Therefore, the equation of line r is  y = (-3/5)x - 1.

The slope of a line perpendicular to Y =-7 is 7. We may use this as a substitution in the inverse slope formula because the slope of Y = -7 is -1.

To find the slope of a line perpendicular to Y = -7, we need to use the inverse slope formula.

The inverse slope formula is m = -1/m1

where m1 represents the original line's slope.

We may use this as a substitution in the inverse slope formula because the slope of Y = -7 is -1.

m = -1/-1

This simplifies to m = 1.

The whole numbers are closed under subtraction only by distributive property else they are not closed under subtraction.

Whole numbers constitute natural numbers including zero. The subset is given by {0, 1, 2, 3, 4, 5, …}, the set does not include fractions, decimals, and negative integers. The set of whole numbers is represented by ‘W’={0, 1, 2, 3, 4, 5, …...}

To check if the whole numbers are closed under subtraction or not we will check out the four properties namely, the closure property, the commutative property, the associative property, and the distributive property.

Let us consider each property one by one -

1. The closure property-

let's take two whole numbers say 5 and 2.

now 5-2=3, but 2-5= -3 which is not a whole number.

Thus, whole numbers are not closed under subtraction by closure property.

2. The commutative property-

let's take two whole numbers say 5 and 2.

now 5-2=3 and 2-5=-3

hence, we get 2-5 ≠ 5-2.

Thus, whole numbers are not closed under subtraction by commutative property.

3. The associative property-

let's take three whole numbers say 5, 3, and 2.

now (5-3)-2 = 0 and 5-(3-2)= 4

hence, we get (5-3)-2 ≠ 5-(3-2).

Thus, whole numbers are not closed under subtraction by associative property.

4. The distributive property-

let's take three whole numbers say 20, 6, and 5.

now, 20 × ( 6 – 5 ) =  20 × 6 – 20 × 5  = 20

         and 20 × ( 6 – 5 ) = 20 × 1 = 20

Hence, 20=20.

Thus, whole numbers are closed under subtraction only by distributive property.

Hence, we can conclude that whole numbers are closed under subtraction only by distributive property.

The percentage of all customers prefer port drink and tea is 17.55%. The result is obtained by multiplying the two percentages of the data.

We have a number of customers.

Of all customers, find the percentage that they prefer port drink and tea!

If 55% prefer soda over port drink, then the ones who prefer port drink is

100% - 55% = 45%

Of the customers who prefer port drink, 61% prefer coffee over tea. So, the ones who prefer tea is

100% - 61% = 39%

From that information, we can get the ones who prefer port drink and tea. Let's say pt = port drink and tea.

pt = 39% × 45%

pt = 0.39 × 0.45

pt = 0.1755

pt = 17.55%
