Answer:

Step-by-step explanation:

The solution to a pair of linear equations will be at their common intersection.

Appears to me to be at (2, 4)

but we could check the math

y = x + 2

4 = 2 + 2

4 = 4  checks out on that line

y = -0.5x + 5

4 = -0.5(2) + 5

4 = -1 + 5

4 = 4  yup, checks out on that line too.

That will be the ONLY point that satisfies both equations.

The solution to the inequality expression is n < -9

The inequality expression is given as

4n - 6(n + 1) > 12

Open the bracket in the above inequality expression

4n - 6n - 6 > 12

Evaluate the like terms

-2n > 18

Divide both sides by -2

Answer:

First choice

Step-by-step explanation:

Looking at the graph, as the line gets further to the right (positive x, also displayed as x-> infinity) the line continues downwards in the y (vertical) direction

Looking at the graph, as the line gets further to the left (negative x, also displayed as x-> -infinity) the line continues downwards in the y (vertical) direction

Thus, the end behavior is -infinity for both ends

Answer:

The above statement is written as

To calculate the gross profit, we need to subtract the cost of goods sold (COGS) from the revenue generated by sales. The revenue generated by sales can be found by multiplying the number of printers sold by the selling price of each printer, which is $1,750.

Revenue generated by sales = 26 x $1,750 = $45,500

The cost of goods sold for each printer is $975, so the total cost of goods sold for all 26 printers is:

Total cost of goods sold = 26 x $975 = $25,350

Therefore, the gross profit can be calculated as:

Gross profit = Revenue generated by sales - Total cost of goods sold

Gross profit = $45,500 - $25,350

Gross profit = $20,150

The gross profit is $20,150.

To calculate the net income, we need to subtract all operating expenses from the gross profit. The operating expenses include your salary ($3,000/month), advertising ($50/month), and office lease ($550/month).

Total operating expenses = $3,000 + $50 + $550

Total operating expenses = $3,600

Therefore, the net income can be calculated as:

Net income = Gross profit - Total operating expenses

Net income = $20,150 - $3,600

Net income = $16,550

The net income is $16,550.

In summary, the gross profit is the revenue generated by sales minus the cost of goods sold, which in this case is $20,150. The net income is the gross profit minus all operating expenses, which in this case is $16,550.

The sale price of a $70 item after a 20% discount is $56.

What is discount?

A discount is a reduction in the price of a product or service. It is often used as a marketing strategy to entice customers to purchase products or services by offering them at a lower price than their original value. Discounts may be expressed as a percentage or a fixed amount of money. For example, a store may offer a 20% discount on all products, or it may offer a discount of $10 on a specific product.

To find the sale price of a $70 item after a 20% discount, we can use the following formula:

Sale price = Original price - Discount amount

First, we need to find the discount amount, which is 20% of the original price:

Discount amount = 20% of $70

Discount amount = 0.20 x $70

Discount amount = $14

Now we can use the formula to find the sale price:

Sale price = $70 - $14

Sale price = $56

Therefore, the sale price of a $70 item after a 20% discount is $56.

Lowest price of an iPhone in Paris is €800 because they stated that one euro is equal to one dollar; when multiplied, the result is 944; this indicates that the iPhone is priced lower in Paris.

It is possible to compare the conversion rates of sterling into the euro and the dollar using the same amount of pounds.

Sterling to Euro : \($750 \times 1.14=6855$\)

Pounds to dollars : \($750 \times 1.39=\$ 1042.5$\)

One phone may be purchased with one pound. The dollar is insufficient to purchase a cell phone, but the euro has enough money to do so. Paris has the lowest pricing for the iPhone from this perspective.

The iPhone SE (2020), which costs Rs 40,000, costs more over a lakh rupees according to the most recent Apple price list for India. Everywhere in the globe, the USA market offers the cheapest prices for iPhones.

The recursive formula for the number of blackberry plants in my yard is Tn = 3Tn-1 where To = 10

The given parameters are:

The number of plants in month n is calculated using:

Tn = Tn-1 * (1 + 200%)

This gives

Tn = 3Tn-1

Hence, the recursive formula for the number of blackberry plants in my yard is Tn = 3Tn-1 where To = 10

This means that n = 1, 2, 3

When n = 1, we have:

T1 = 3To = 3 * 10 = 30

When n = 2, we have:

T2 = 3T1 = 3 * 30 = 90

90 is greater than the maximum number of plant the backyard can contain

Hence, the number of plants after 1 month is 30 and the plants in the backyard would exceed 50 plants before the end of the 2 months

Answer:

h = 4cm

Step-by-step explanation:

Diameter = 18cm

Radius = Diameter/2 = 18/2 = 9cm

V = 1/3*pi*r^2*h

We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.

So,

108 pi = 1/3*pi*9^2*h

108 pi = (81pi*h)/3

multiply 3 from both side

108pi*3 = (81pi*h)/3 *3

324pi = 81pi*h

Now divide the 81pi from both side

324pi/81pi = (81pi*h)/81pi

4 = h

So the height is 4cm

Answer:

h = 4cm

Step-by-step explanation:

Diameter = 18cm

Radius = Diameter/2 = 18/2 = 9cm

V = 1/3*pi*r^2*h

We know that the volume is 108pi cm^3. We can just plug in 108pi cm^3 for V and we also know that our Radius (r) is 2.

So,

108 pi = 1/3*pi*9^2*h

108 pi = (81pi*h)/3

multiply 3 from both side

108pi*3 = (81pi*h)/3 *3

324pi = 81pi*h

Now divide the 81pi from both side

324pi/81pi = (81pi*h)/81pi

4 = h

So the height is 4cm

Answer:

\(\boxed{Option \ C}\)

Step-by-step explanation:

\(y = -x^2+3x+18\\y = -2x+4\)

Equating both equations

=> \(-x^2+3x+18 = -2x+4\\x^2-2x-3x+4-18 = 0\\x^2-5x-14=0\)

Using mid term break formula

=> \(x^2-7x+2x-14=0\\x(x-7)+2(x-7)=0\\Taking \ (x-7) \ common\\(x+2)(x-7) = 0\)

Either,

x + 2 = 0     OR    x - 7 = 0

 x = -2         OR      x = 7

For, x = -2 , y is

=> y = -2x+4

=> y = -2(-2)+4

=> y = 4+4

=> y = 8

So, the ordered pair is (-2,8)

For x = 7 , y is

=> y = -2(7)+4

=> y = -14+4

=> y = -10

So, the ordered pair for this is (7, -10)

Solution Set = {(-2,8),(7,-10)}

Answer:

The answer is option C

Step-by-step explanation:

y = - x² + 3x + 18

y = - 2x + 4

Since they are both equal to y we equate them

That's,

- x² + 3x + 18 = - 2x + 4

x² - 5x - 14 = 0

Solve the quadratic equation

x² - 5x - 14 = 0

x² + 2x - 7x - 14 = 0

x(x + 2) - 7( x + 2) = 0

( x - 7)(x + 2) = 0

x - 7 = 0 x + 2 = 0

x = 7 x = - 2

Substitute the values of x into y = - 2x + 4

That's

when x = 7 when x = - 2

y = - 2(7) + 4 y = - 2(-2) + 4

y = - 14 + 4 y = 4 + 4

y = - 10 y = 8

So the solutions are

On an average 9.043 \(\times10^{5}\) beats more does the mouse heart beats in a day.

The average human heart beats = 1.037\(\times10^5\) times per day.

The approximate average mouse heart beats = 1.008\(\times10^6\) times per day.

We have to find the how many beats more does the mouse heart beats in a day.

Since we have to find the more heart beat of mouse comparing to the human heartbeats. So we subtract their heart beat.

The human heartbeats have \(10^5\) while mouse heartbeats have \(10^6\). So we first equal the power of 10. After equal the power we can easily find the value of the more heart beat of mouse.

We can write,

The average human heart beats = 0.1037\(\times10^6\)

Now,

The more heartbeats of mouse = average mouse heart beats − average human heart beats.

The more heartbeats of mouse \(= 1.008\times10^6-0.1037\times10^6\)

The more heartbeats of mouse \(=(1.008-0.1037)\times10^{6}\)

The more heartbeats of mouse = 0.9043\(\times10^{6}\)

The more heartbeats of mouse = 9.043\(\times10^{5}\)

Hence, on an average 9.043\(\times10^{5}\) beats more does the mouse heart beats in a day.
