Answer:

  35

Step-by-step explanation:

The equations will be "consistent" when they describe lines that are not parallel.

The slope of a line whose equation is written in this form is the opposite of the ratio of the y-coefficient to the x-coefficient:

  line 1 slope = -8/20 = -2/5

  line 2 slope = -14/35 = -2/5

These lines have the same slope, so will be parallel unless they have the same y-intercept.

The y-intercept of each line is the ratio of the constant to the y-coefficient:

  line 1 y-intercept = 20/20 = 1

  line 2 y-intercept = k/35

We want these lines to have the same y-intercept so that they are not inconsistent. This requires ...

  k/35 = 1

  k = 35

For the equations to be consistent, we must have k = 35.

Additional comment

Linear equations are generally categorized as "consistent" or "inconsistent," and "dependent" or "independent."

Equations are "inconsistent" if there are no values of the variables that satisfy all of the equations. They are "dependent" if they describe exactly the same relation between the variables. "Consistent" equations may be "dependent" (describing the same line, as here), or "independent" (describing lines with different slopes.)

Based on the calculations, the formula of this sinusoidal function is equal to f(x) = 6cos(2x) + 4.

Mathematically, the standard equation of a cosine function is given by:

y = Acos(Bx - C) + D

Where:

For the amplitude, we have:

A = maxline - midline

A = 10 - 4

Amplitude, A = 6.

Since the maxline to the midpoint is euqal to π/4, we have:

¼ × P = π/4

4P = 4π

P = π

For the value of B, we have:

B = 2π/P

B = 2π/π

B = 2.

Since there isn't any phase shift, the value of C is equal to zero (0) and D is equal to 4.

Next, we would substitute the parameters into the cosine function:

y = Acos(Bx - C) + D

y = 6cos(2x - 0) + 4

f(x) = y = 6cos(2x) + 4.

The x-intercept of p(x) is x = 2, the x-intercept of g(x) is x = 0, then the correct option is B.

For a function f(x), the x-intercept is the value of x such that:

f(x) = 0.

Here we have:

p(x) = log₂(x - 1)

Remember that:

logₙ(1)  = 0

For any base n, then the x-intercept of p(x) is x = 2, because:

p(2) = log₂(2 - 1) = log₂(1) = 0.

The other function is:

g(x) = 2ˣ - 1

Remember that any number to the power of zero is equal to 1, then:

g(0) = 2⁰ - 1 = 1 - 1 = 0

Answer:

[tex]21 \frac{1}{3}[/tex] fit into the product

Step-by-step explanation:

so you want to convert [tex]2 \frac{2}{3}[/tex] into a fraction by multiplying 2 by 3 and adding it to the 2. This will give you (3 * 2) = 6 => 6+2=8 which is the numerator. So the fraction becomes [tex]\frac{8}{3}[/tex] and since the two fractions are equal they both become this. So now you have [tex]\frac{8}{3} * \frac{8}{3}[/tex] which can be calculated by multiplying the numerators and denominators. This gives you [tex]\frac{8*8}{3*3} = \frac{64}{9}[/tex]. Now this just gives you the product but the question is asking you how many one thirds is the product. This is essentially saying how many 1/3 fit into the product or in other words what is the product divided by 1/3. This gives you the equation [tex]\frac{64}{9} \div \frac{1}{3}[/tex] which can be calculated by changing the sign to multiplication and flipping the second fraction (1/3 => 3/1) This gives you the equation [tex]\frac{64}{9} * \frac{3}{1} = \frac{64 * 3}{3 * 3} = \frac{64}{3}[/tex]. I rewrote the 9 as 3 * 3 in the equation so you can see that we can just cancel out the 3. Since if have a number and multiply it by "x" and divide by "x" you just have the original number. So now you have 64/3 which simplifies to [tex]21 \frac{1}{3}[/tex]

hope this helps

Answer:

P(w) = 3w+4

Step-by-step explanation:

For a Linear Equation , it takes the Form y = mx + c

where c is the Constant which is y-value at x=0

and the m is the Slope which is the change in y-value for a 1-unit change in x-value

So for our Question

y-value is represented by P(w) , Number of Rats

x-value is represented by w , Number of Weeks

So the Constant (c) is the P(w) at w=0 which is 4

and the Slope is the Change in P(w) value as w changes by 1 unit , which from week 0 to week 1 , P(w) changed from 4 to 7 , so the Change =7-4=3

Then the Slope m = 3

So the Linear Equation will be P = mw+c

Then P(w) = 3w+4

Answer: Choice A) It has a range of 17

Reason:

The smallest value is 8 and the largest is 14. The range is the distance between these min and max

range = max - min = 14 - 8 = 6

So the range is 6 instead of 17.

The range of a data set is the difference between maximum and minimum thus the range of the given data set 8, 10, 10, 12, 12, 12, 12, 14, 14,16 is 8 so option (A) does not describe the data set.

Mode is the highest frequency number while the median is the middle value of a data set after writing in either an increasing or decreasing manner.

For example;

Set { 1,2,2,3,4,5,6} here mode is 2 and median is 3.

As per the given data set.

8, 10, 10, 12, 12, 12, 12, 14, 14,16

The range = maximum - minimum

Range = 16 - 8 = 8

The median of the data set is 12.

The mode is the highest frequency thus 12 is the mode of the data set.

Hence "The range of a data set is the difference between maximum and minimum thus the range of the given data set 8, 10, 10, 12, 12, 12, 12, 14, 14,16 is 8".

Arianna can travel 960 mi in 16 hours.

Speed is defined as the rate of change of position of an object in any direction.

Given that, Arianna drove 180 miles in 3 hours.

As we know, Speed is the ratio of distance to the time in which the distance was covered.

Speed = distance/time

Ariana's speed = 180/3 = 60 mi/hr

Therefore, time taken by her to travel 960 mi = 960/60 = 16 hr.

Hence, Arianna can travel 960 mi in 16 hours.

The amount of gross profit earned by Abbey Co. on the above transactions is $7,554.00

Step-by-step explanation:

What is the gross profit of Abbey Co?

Note that after sales of goods of $29,300 whose cost is $20,510 to Gomez Co, Gomez returned goods whose selling price is $2,500 and cost originally $1,800 to Abbey Co.

The implication of such goods returned is that $2,500 would be deducted from selling price and $1,800 would be deducted from cost of goods sold.

selling price=$29,300-$2,500

selling price=$26,800.00

cost of goods sold=$20,510-$1,800

cost of goods sold=$18,710.00

Note again that Gomez paid the invoice within the discount period, which means that net sales is the selling price of $26,800.00  minus 2% discount(2/15 means a discount of 2% is available if credit sales is settled in cash within the first 15 days of making sales0

net sales=$26,800.00*(1-2%)

net sales=$26,264.00

The gross profit is net sales minus the cost of goods sold

gross profit= $26,264.00-$18,710.00

Answer:

Look at the picture.

The solution to the given proportion (x-1)/5 = (x-1)/2 is equal to x = 1.

To solve the proportion (x-1)/5 = (x-1)/2, we need to find the value of x that satisfies the equation. Cross-multiplication is a common method used to solve proportions.

First, cross-multiply the equation:

2(x - 1) = 5(x - 1)

Now, distribute the values on both sides:

2x - 2 = 5x - 5

Next, isolate the variable x on one side of the equation. Let's move all terms containing x to the left side of the equation by subtracting 2x from both sides:

2x - 2 - 2x = 5x - 5 - 2x

-2 = 3x - 5

Now, let's move the constant term (-5) to the other side of the equation by adding 5 to both sides:

-2 + 5 = 3x - 5 + 5

3 = 3x

Finally, to find the value of x, divide both sides by 3:

As the length AB increases, the measure of C increases

As the length AB increases, the measure of C increases.

An angle is formed when two lines or rays meet at a single point. The common point is referred to as the vertex. The length of the angle formed when two rays or arms intersect at a common vertex is known as an angle measure in geometry.

Angles and sides in relation to one another:

The biggest side and angle of any triangle are in opposition to one another.

The smallest side and angle in every triangle are on opposing sides.

The middle side and middle angle are always in opposition to one another in triangles.

When we extend vertex A further to the left of vertex B,

we increase the side length of AB.

As the length AB increases, the measure of opposite angle increases.

Let C be the angle opposite to AB.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are the lengths, that are x, y and z.

The length of one side of a triangle is 2 feet less than three times the length of its second side, hence:

x = 3y - 2.

The length of the third side is 3/4 of the sun of the lengths of the first two sides, hence:

Find the lengths of all three sides if the perimeter of the triangle is 17.5 feet, hence:
