Step-by-step explanation:

Simplifying

8x + -10 + 10 + 4x = -10 + 6x + 6x + 10

Reorder the terms:

-10 + 10 + 8x + 4x = -10 + 6x + 6x + 10

Combine like terms: -10 + 10 = 0

0 + 8x + 4x = -10 + 6x + 6x + 10

8x + 4x = -10 + 6x + 6x + 10

Combine like terms: 8x + 4x = 12x

12x = -10 + 6x + 6x + 10

Reorder the terms:

12x = -10 + 10 + 6x + 6x

Combine like terms: -10 + 10 = 0

12x = 0 + 6x + 6x

12x = 6x + 6x

Combine like terms: 6x + 6x = 12x

12x = 12x

Add '-12x' to each side of the equation.

12x + -12x = 12x + -12x

Integer represents the total change in the time when you use 5 clues with the condition of using 3 free clues is equal to 10 minutes.

As given in the question,

Number of free clues =3

Total number of clues used to escape from a room = 5clues

Out of these 5 clues, 3 clues are free to use. Hence these 3 clues do not result in any time change.

Hence total time elapsed after usage of 3 clues = 0

Each removes 5 minutes from your remaining time

Integer represents the total change in the time for the usage of 4th and 5th clue = 10 minutes

So overall change in timeline after consuming 5 clues = 10 minutes since each of the 4th and 5th clue results in decrease of 5 minutes each; thus effecting 10 minutes total time change (reduction)

Therefore, integer represents the total change in the time when you use 5 clues with the condition of using 3 free clues is equal to 10 minutes.

When he spends $52 in total, the number of bottles of water and protein bars that he buys will be 40 and 20 respectively.

It should be noted that an equation is used to show the relationship between the variables.

In this case, Kawan buys some protein bars at $0.80 each and bottled water at $0.90 each for a group hike and he buys twice as many bottles of water as protein bars.

Let x = the number of protein bars

Table waters = 2x

Therefore, the equation will be:

0.8x + 0.9(2x) = 52

0.8x + 1.8x = 52

2.6x = 52

Divide

x = 52/2.6

x = 20

The number of proteins bars is 20.

The number of water will be:

= 2x.

= 2 × 20 = 40

Time taken to cover path around the park if he runs at speed 5miles/hour is 15.96min

What is Speed ?

Speed indicates how quickly something or someone is moving. If you know how far something has traveled and how long it took to get there, you can calculate its average speed. Speed is calculated as follows: speed = distance x time.

Given that,

Time taken when Bob runs 4miles/hour = 20min

Time taken when Bob runs 5miles/hour = ?

First we have to find the distance of the path around the circle

Distance = speed x time

               = 4 x 20/60

               = 4/3 miles

               = 1.33 miles

Now to calculate the time when he ran 5 miles/hours:

Time = distance / speed

         = 1.33 / 5

         = 0.266hours

0r

         = 0.266 x 60 min

         = 15.96 min

Hence, its will take 15.96min to cover the path around the park

Based on the given ordered pairs, yes, the relation is a function.

A function simply refers to a mathematical expression which is used to define and represent the relationship that exists between two or more variables. This ultimately implies that, a function is typically used for uniquely mapping an input variable to an output variable.

Based on the ordered pairs shown above, we can reasonably infer and logically deduce that these ordered pairs represent a function because the elements of the set of "x" are uniquely mapped to the elements of the set of "y" as shown below:

x              y__

A graph of a proportional relationship can be used to find any ratio in the proportional relationship when the graph passes through the origin.

A connection is proportional if its graph is a line that goes through the origin. The ratio is not proportionate if it is not a line or ray that doesn't accomplish this. K = y/x is the equation for the proportionality constant. The equation for the slope of a straight line with respect to the origin is the same as this.

The solution of the given inequality for the value of x, x ≥ 1/2.

In mathematics, inequalities specify the connection between two non-equal numbers. Equal does not imply inequality. Typically, we use the "not equal sign" to indicate that two values are not equal. But several inequalities are utilized to compare the numbers, whether it is less than or higher than. Both mathematical phrases, equations, and inequalities are created by connecting two expressions. The equal sign (=) indicates that two expressions in an equation are believed to be equivalent. The symbols >,<,≥,≤,≠ or indicate that the two expressions in inequality are not always equal.

The time that it will take for it to fall 48 feet will be ✓3 seconds.

From the information, the distance s that an object falls varies directly with the square of the time, t , of the fall and an object falls 16 feet in one second.

This will be:

s = kt²

s = distance

k = constant

t = time

s = kt²

16 = 1²k

k = 16

Therefore, the time that it will take for it to fall 48 feet will be:

s = kt²

48 = 16t²

t² = 48 / 16

t² = 3

t = ✓3

Step-by-step explanation:

Using the polynomial expression, the non-real solutions are x = (2 + i√26)/3 and  x = (2 - i√26)/3

Polynomial expressions are mathematical statements that are represented by variables, coefficients and operators

The equation of the polynomial expression is given as:

3x^3 + 14x^2 - 14x + 60 = 0

From the question, we have

Real solution = -6

Rewrite the above equation as

x = -6

Add 6 to both sides of the equation

So, we have

x + 6 = 0

The next step is to divide the polynomial equation 3x^3 + 14x^2 - 14x + 60 = 0 by x + 6 = 0

This is represented as

3x^3 + 14x^2 - 14x + 60/x + 6

Using a graphing calculator, we have

3x^3 + 14x^2 - 14x + 60/x + 6 = 3x^2 - 4x + 10

Next, we determine the solution of the quadratic expression 3x^2 - 4x + 10 using a quadratic formula

So, we have

x = (-b ± √(b² - 4ac))/2a

This gives

x = (4 ± √((-4)² - 4 * 3 * 10))/2 * 3

So, we have

x = (4 ± √-104)/6

This gives

x = (4 ± 2√-26)/6

Divide

x = (2 ± √-26)/3

Rewrite as

x = (2 ± i√26)/3

Split

x = (2 + i√26)/3 and  x = (2 - i√26)/3

Hence, the non-real solutions of the polynomial expression are x = (2 + i√26)/3 and  x = (2 - i√26)/3

The cost of the jalapeno poppers is $11.09    .

In the question ,

it is given that

Cost of the nachos = $18.85

amount paid by each friend = $9.98

amount paid by three friends = 9.98*3 = $29.94

let the cost of jalapeno poppers = $x

So according to the question

the total amount paid by three friends = cost of nachos + cost of jalapeno poppers

Substituting the values from above , in the equation we get

29.94 = 18.85 + x

simplifying further , we get

x = 29.94 - 18.85

x = 11.09

Therefore , the cost of the jalapeno poppers is $11.09  .

Step-by-step explanation:

See that the slope of the parabola changes at x=4

And left of x=4, the slope is positive, meaning the value is increasing (you can also see it directly from the graph)

Right of x=4, the slope is negative, meaning the value of the graph is decreasing. Thus the answer is A
