This is what I came up with

5. (6,32)

6. That means that when six kites are order it would be the same cost from each company

Step-by-step explanation:

The solution y = 3x + 12 represents a linear relationship between two variables in the given scenario, with an initial cost of $12 and an additional cost of $3 for each unit increase in the independent variable "x." The interpretation of this relationship depends on the specific context of the problem.

The given system of equations can be written in slope-intercept form, which is in the form y = mx + b, where "m" represents the slope of the line, and "b" represents the y-intercept. In this context, the system is as follows:

4 = 3m + b

12 = b

We can solve this system to find the values of "m" and "b."

First, we already know that b = 12 from the second equation.

Now, substitute this value into the first equation:

4 = 3m + 12

Next, isolate "3m" by subtracting 12 from both sides of the equation:

3m = 4 - 12

3m = -8

Finally, divide both sides by 3 to solve for "m":

m = -8/3

So, we have found that m = -8/3 and b = 12.

Now, let's interpret the solution in the context of the scenario:

The equation y = 3x + 12 represents the relationship between "x" (which could represent a quantity like time or another variable) and "y" (which could represent a cost, height, or another quantity). In this specific case, it seems like the equation describes a linear relationship between two variables.

In terms of the scenario, it could mean that there is an initial cost of $12 (the y-intercept) and an additional cost of $3 for each unit increase in "x." This interpretation depends on the context of the problem. For example, if "x" represents the number of items purchased, then $12 could be an initial fee, and $3 could be the cost per item.

the average rate of change of the function over the interval [tex]\(10 < x < 15\)[/tex] is [tex]\( -\frac{6}{5} \)[/tex].

To find the average rate of change of the function over the interval (10 < x < 15), we use the formula:

[tex]\[ \text{Average Rate of Change} = \frac{\text{Change in } f(x)}{\text{Change in } x} \][/tex]

We can calculate the change in [tex]\(f(x)\)[/tex] by subtracting the function values at the end and start of the interval, and the change in x by subtracting the end and start values of x.

Given the function values:

- [tex]\(f(10) = 30\)[/tex]

- [tex]\(f(15) = 24\)[/tex]

And the interval [tex]\(10 < x < 15\)[/tex], the change in [tex]\(f(x)\) is \(f(15) - f(10) = 24 - 30 = -6\)[/tex].

The change in x is [tex]\(15 - 10 = 5\)[/tex].

Now, we plug these values into the formula for the average rate of change:

[tex]\[ \text{Average Rate of Change} = \frac{-6}{5} \][/tex]

So, the average rate of change of the function over the interval [tex]\(10 < x < 15\)[/tex] is [tex]\( -\frac{6}{5} \)[/tex].

Step-by-step explanation:

To divide fractions, multiply the first fraction by the reciprocal of the second fraction. Simplify the resulting fraction.

To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction. So, the reciprocal of 7/6 is 6/7. Therefore, 49/50 ÷ 7/6 = 49/50 x 6/7. When we multiply the numerators (49 x 6) and the denominators (50 x 7), we get 294/350. This fraction can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 14. Therefore, 294/350 simplifies to 21/25.

Answer:3/2

Step-by-step explanation:

The system has one solution

Step-by-step explanation:

Let us revise the type of the solutions of a system of equations

The system of equations is:

y = 2x - 12 ⇒ (1)

y = 3x + 12 ⇒ (2)

∵ The equations are in its simplest form

∵ The coefficients of x in the two equations are different

- That is the 1st case above

∴ The system has one solution

Let us prove that by solving the system

To solve the system of equations equate (1) and (2) to find x

∵ 3x + 12 = 2x - 12

- Subtract 2x from both sides

∴ x + 12 = -12

- Subtract -12 from both sides

∴ x = -24

- Substitute the value of x in equation (1) or (2) to find y

∵ y = 3(-24) + 12

∴ y = -72 + 12

∴ y = -60

∴ The solution of the system is (-24 , -60)

The system has one solution

f^-1(x) = sq.rt 5(x - 10)/5, sq.rt 5(x - 10)/5 is the inverse of y = 5x^2 +10

Step-by-step explanation:

interchanging the variables

x = 5y^2 + 10

5y^2 +10 = x

5y^2 = x - 10

dividing by 5

5y^2/5 = x/5 + -10/5

y^2 = x/5 + - 10/5

y^2 = x/5 - 2

y = 5 (x-10) 0/5 (sq.rt)

g(5x^2 + 10) = 5x/5

g(5x^2 + 10) = x

Final answer:

To calculate the time it will take for the diver to reach a depth of 250 feet based on the given information.

Explanation:

The depth of a diver is directly proportional to the time since the diver entered the water.

To find the time it will take to reach a depth of 250 feet, we can set up a proportion using the given information: 80 ft / 45 min = 250 ft / x min. Cross-multiply and solve for x to find the time.

Therefore, the time it will take to reach a depth of 250 feet is approximately 140.6 minutes.

Answer:

∠ ABC = ∠ DBE = 65°

∠ ABD = ∠ CBE = 115°

Step-by-step explanation:

See the diagram attached to this question.

Now, ∠ ABC and ∠ DBE are two vertically opposite angles.

So, 3x + 38 = 5x + 20

⇒ 2x = 18

⇒ x = 9

So, ∠ ABC = ∠ DBE = 3(9) + 38 = 65° (Answer)

Again, ∠ ABC and ∠ ABD are supplementary angles.

Then, ∠ ABC + ∠ ABD = 180°

⇒ ∠ ABD = 180° - 65° = 115°

And ∠ ABD = ∠ CBE {Vertically opposite angles}

So, ∠ ABD = ∠ CBE = 115° (Answer)

Step-by-step explanation:

Step 1: Define

Identify bounded region. See attached graph.

y = 3x - 6

y = -2x + 8

Bounded by x-axis and between those 2 lines (already pre-determined; taking an integral always takes it to the x-axis).

Step 2: Analyze Graph

See attached graph.

Looking at our systems of equations on the graph, we see that our limits of integration is from x = 2 to x = 4.

We don't have a continuous top function through the interval [2, 4] (it switches from y = 3x - 6 to y = -2x + 8), so we need to split it into 2 integrals to find the total area.

We can either use the graph and identify the intersection point, which is x = 2.8, or we can solve it algebraically (systems of equations - substitution method):

Our 2 intervals would be [2, 14/5] and [14/5, 4] for their respective integrals.

Step 3: Find Area

Our top functions are the linear lines y = 3x - 6 and y = -2x + 8 and our continuous bottom function is the x-axis (x = 0).

We can redefine the linear lines as f₁(x) = 3x - 6, f₂(x) = -2x + 8, and g(x) = 0.

Integration

We have found the area bounded by the x-axis and linear lines y = 3x - 6 and y = -2x + 8.

Answer:

A = 12/5 units

Step-by-step explanation:

USING ALGEBRA:

We can find the intersection point between these two lines;

Set these two equations equal to each other.

Add 2x to both sides of the equation.

Add 6 to both sides of the equation.

Divide both sides of the equation by 5.

Find the y-value where these points intersect by plugging this x-value back into either equation.

Multiply and simplify.

Multiply 6 by (5/5) to get common denominators.

Subtract and simplify.

These two lines intersect at the point 12/5. This is the height of the triangle formed by these two lines and the x-axis.

Now let's find the roots of these equations (where they touch the x-axis) so we can determine the base of the triangle.

Set both equations equal to 0.

Add 6 both sides of the equation.

Divide both sides of the equation by 3.

Set the second equation equal to 0.

Add 2x to both sides of the equation.

Divide both sides of the equation by 2.

The base of the triangle is from (2,0) to (4,0), making it a length of 2 units.

The height of the triangle is 12/5 units.

Formula for the Area of a Triangle:

Substitute 2 for b and 14/5 for h.

Multiply and simplify.

The area of the region bounded by the lines y = 3x - 6 and y = -2x + 8 between the x-axis is 12/5 units.

Answer:

9120

Step-by-step explanation:

The system of linear inequalities are:

[tex]a + b \geq 20\\\\2.50a + 7b\leq 80[/tex]

Solution:

Let "a" be the number of small candles bought

Let "b" be the number of large candles bought

Cost of each small candle = $ 2.50

Cost of each large candle = $ 7

He needs to buy at least 20 candles

Therefore, number of small candles and number of large candles bought must be at least 20

Thus, we frame a inequality as:

[tex]a + b\geq 20[/tex]

"at least" means greater than or equal to

Here, we used "greater or equal to" symbol because, he can buy 20 candles or more than 20 candles also

He can spend no more than 80 dollars

Which means, he spend maximum 80 dollars or less than 80 dollars also

So we have to use "less than or equal to" symbol

Thus, we frame a inequality as:

Number of small candles bought x Cost of 1 small candle + number of large candles bought x Cost of 1 large candle [tex]\leq[/tex] 80

[tex]a \times 2.50 + b \times 7 \leq 80\\\\2.50a + 7b\leq 80[/tex]

Thus the system of linear inequalities are:

[tex]a + b \geq 20\\\\2.50a + 7b\leq 80[/tex]
