Answer:

Step-by-step explanation:

it would be "c" because the question asks for the number that makes the inequality true

4x≤ x+3

the graph in c is saying that every number that is 1 or less than 1 makes the inequality true. so lets take -7 as an example

4 x -7=-28

-28+3=-25

-25 is greater than -28 so the inequality is true. the reason why graph d doesnt work is because if we plug in 2 into the equation, then 4x =8 and x+3=5

5 is not greater than 8 so it doesnt work

The equation does not hold true, the ordered pair (3, 10) is not a solution of the equation y = 2x + 6.In this way, we can determine whether an ordered pair is a solution of the given equation or not.

Given the equation y = 2x + 6To determine if an ordered pair is a solution of this equation or not, substitute the values of x and y in the equation. If the equation holds true, then the ordered pair is a solution.

If it is not true, then the ordered pair is not a solution.For example, let's consider the ordered pair (1, 8).

Here, x = 1 and y = 8.Substituting these values in the given equation,

we get: y = 2x + 6 => 8 = 2(1) + 6 => 8 = 8 Since the equation holds true,

the ordered pair (1, 8) is a solution of the equation y = 2x + 6.

Now, let's consider another ordered pair, say (3, 10). Here, x = 3 and y = 10.Substituting these values in the given equation, we get: y = 2x + 6 => 10 = 2(3) + 6 => 10 = 12

Answer:

        x = 4 + √ 21

        x  =  4 - √ 21

Step-by-step explanation:

Determine the exact values of x for x^2 - 8x - 5 = 0 using COMPLETING THE SQUARE:

x^2 - 8x - 5 = 0

x^2  -  8x = 5

( -8/2 )^2 = 16

x^2 - 8x + 16 = 5 + 16

x^2 - 8x + 16 = 21

x - 4 = ±√21

x - 4  = ±√21

The exact values of x are:  x = 4 +√21  and x  = 4 - √21

I hope this helps!

Answer:

x = 4 - √21.
x = 4 + √21

Step-by-step explanation:

To determine the exact values of x for x^2 - 8x - 5 = 0 using completing the square, follow these steps:

Move the constant term to the right side of the equation: x^2 - 8x = 5

Take half of the coefficient of x (-8/2 = -4) and square it (-4^2 = 16): x^2 - 8x + 16 = 5 + 16

Simplify the right side: x^2 - 8x + 16 = 21

Factor the left side as a perfect square: (x - 4)^2 = 21

Take the square root of both sides: x - 4 = ±√21

Add 4 to both sides: x = 4 ±√21

Therefore, the exact values of x for x^2 - 8x - 5 = 0 are x = 4 + √21 and x = 4 - √21.

(3xy³ + 5x²y⁴)  (3xy³ - 5x²y⁴)

Step-by-step explanation:

Factorize polynomials:

Use exponent law:

                   \(\boxed{\bf a^{m*n}=(a^m)^n} \ & \\\\\boxed{\bf a^m * b^m = (a*b)^m}\)

9x²y⁶ = 3²* x² * y³*² = 3² * x² * (y³)² = (3xy³)²

25x⁴y⁸ = 5² * x²*² * y⁴*² = 5² * (x²)² * (y⁴)² = (5x²y⁴)²

Now use the identity:  a² - b² = (a +b) (a -b)

Here, a = 3xy³ & b = 5x²y⁴

9x²y⁶ - 25x⁴y⁸ = 3²x²(y³)² - 5²(x²)² (y⁴)²

                       = (3xy³)² - (5x²y⁴)²

                      = (3xy³ + 5x²y⁴)  (3xy³ - 5x²y⁴)

Answer:

The nth term is Tn = 2[T(n- 1) -2]

The next term is 356

Step-by-step explanation:

Given

Terms: 15,26,48,92,180

Solving (a) : The recursive n term

We have:

T1 = 15

T2 = 26 = 13 * 2 = (15 - 2) * 2

T3 = 48 = 24 * 2 = (26 - 2) * 2

T4 = 92 = 46 * 2 = (48 - 2) * 2

T5 = 180 = 90 * 2 = (92 - 2) * 2

So, the nth term can be represented as:

Tn = [T(n-1) - 2] * 2

Tn = 2[T(n-1) - 2]

The next term is the 6th term.

So, substitute 6 for n in the above formula.

T6 = 2 * [T(6 - 1) - 2]

T6 = 2 * [T5 - 2]

Substitute 180 for T5

T6 = 2 * (180 - 2)

T6 = 2 * 178

T6 = 356

Answer:

108 inches²

Step-by-step explanation:

Rectangular prism = cuboid

To find how much paper is required to cover the box, we need to find the TSA of the cuboid.

TSA of cuboid = 2 [LB + LH + HB] = 2 [ (3×4) + (3×6) + (4×6) ] = 2 [ 12+18+24 ] = 2 × 54 = 108 inches²

A chi-squared test was used to examine the relationship between level of hiking expertise and direction taken when lost. With a calculated chi-squared value of 4.6875, which is less than the critical value of 5.991, there is no evidence of an association in the sample of 200 hikers.

To determine whether there is an association between the level of hiking expertise and the direction the hiker would take if lost, we can perform a chi-squared test for independence.

First, we need to calculate the expected counts for each cell under the assumption that there is no association between the variables. We can do this by multiplying the row total and column total for each cell and dividing by the grand total.

The expected counts are as follows:

                       Uphill      Downhill      Stay in same place

Novice            9.375        18.75                 21.875

Experienced  10.625       21.25                24.125

Next, we can calculate the chi-squared test statistic:

chi-squared = sum((observed count - expected count)^2 / expected count)

Using the observed counts from the table and the expected counts calculated above, we get:

chi-squared = 4.6875

Using a chi-squared distribution table with 2 degrees of freedom (2 rows - 1, 3 columns - 1), we find that the critical value for a significance level of 0.05 is 5.991.

Since the calculated chi-squared value (4.6875) is less than the critical value (5.991), we fail to reject the null hypothesis that there is no association between the level of hiking expertise and the direction the hiker would take if lost.

Therefore, we do not have convincing evidence of an association between the two variables based on this sample of 200 hikers.

A mountain rescue service wants to study the behavior of lost hikers. Knowing more about the direction in which lost hikers tend to walk would allow more effective search strategies.

Two hundred hikers are selected at random from those applying for hiking permits, and they are asked whether they would head uphill, downhill, or stay in the same place if they became lost while hiking. Each hiker was also classified as to whether he or she was a novice or an experienced hiker. The following table is a summary of the data collected.

                       Uphill          Direction Downhill             Stay in same place

If a team of 3 trucks is going to haul 23 tons of rocks then the decimal equivalent of 23 is 7.67.

Given that a team of 3 trucks is going to haul 23 tons of rocks.

We are required to find the decimal equivalent of 23.

The decimal numeral system is basically the standard system for denoting integer and non-integer numbers. It is also the extension to non-integer numbers of the Hindu–Arabic numeral system.

To find the decimal equivalent we need to divide 23 by 3.

By dividing 23 by 3, we will get 7.66666.

After rounding off we will get 7.67.

Hence if a team of 3 trucks is going to haul 23 tons of rocks then the decimal equivalent of 23 is 7.67.

Step-by-step explanation:

The function f(x) = -2(4)ˣ⁺¹ +140 represents the number of tokens a child has x hours after arriving at an arcade. The practical domain and range of the function are x ≥ 0 and The practical range of the situation is [140, ∞).

The given function is f(x) = -2(4)ˣ⁺¹+ 140, which represents the number of tokens a child has x hours after arriving at an arcade.

To determine the practical domain and range of the function, we need to consider the constraints and limitations of the situation.

For the practical domain, we need to identify the valid values for x, which in this case represents the number of hours the child has been at the arcade. Since time cannot be negative in this context, the practical domain is x ≥ 0, meaning x is a non-negative number or zero.

Therefore, the practical domain of the situation is x ≥ 0.

For the practical range, we need to determine the possible values for the number of tokens the child can have. Looking at the given function, we can see that the term -2(4)ˣ⁺¹represents a decreasing exponential function as x increases. The constant term +140 is added to shift the graph upward.

Since the exponential term decreases as x increases, the function will have a maximum value at x = 0 and approach negative infinity as x approaches infinity. However, due to the presence of the +140 term, the actual range will be shifted upward by 140 units.

Therefore, the practical range of the situation will be all real numbers greater than or equal to 140. In interval notation, we can express it as [140, ∞).

To summarize:

- The practical domain of the situation is x ≥ 0.

- The practical range of the situation is [140, ∞).
