Answer:

B. Kyle earned $4, each week for 3 weeks, for helping his brother maw the kwn. How much money did Kyle have at the end of 3 weeks ?

Step-by-step explanation:

Option B answers the question.

Analyzing B

[tex]Earnings = \$4[/tex] weekly

[tex]Duration = 3\ weeks[/tex]

Total Earnings is calculated as thus:

[tex]Total = Earnings * Duration[/tex]

[tex]Total = \$4 * 3[/tex]

[tex]Total = \$12[/tex]

Hence:

[tex]\$4 * 3 = \$12[/tex]

1)

[tex]\frac{d^2 - 9}{d^2 - 7d + 12} = \frac{(d - 3)(d + 3)}{(d - 3)(d - 4)} = \frac{d + 3}{d - 4}[/tex]

2)

[tex]\frac{m^2 + 2mn + n^2}{m^2 - n^2} = \frac{(m + n)(m + n)}{(m - n)(m + n)} = \frac{m + n}{m - n}[/tex]

3)

[tex]\frac{x^2 + xy - 6y^2}{x^2 - 3xy + 2y^2} = \frac{(x + 3y)(x - 2y)}{(x - y)(x - 2y)} = \frac{x + 3y}{x - y}[/tex]

1. [tex] \bf \dfrac{ {d}^{2} - 9 }{ {d}^{2} - 7d + 12 } [/tex]

[tex] \tt : \implies \dfrac{ {d}^{2} - (3)^{2} }{ {d}^{2} - 3d - 4d + 12 } [/tex]

By using identinty a² - b² = (a + b)(a - b) in numerator and splitting method in denominator :

[tex] \tt : \implies \dfrac{ (d+3)(d-3) }{ {d}^{2} - 3d - 4d + 12 } [/tex]

[tex] \tt : \implies \dfrac{ (d+3)(d-3) }{d(d - 3) - 4(d - 3)} [/tex]

[tex] \tt : \implies \dfrac{ (d+3)\cancel{(d-3)} }{\cancel{(d - 3)}(d - 4)} [/tex]

[tex] \tt : \implies \dfrac{d+3}{d - 4} [/tex]

Hence, answer is [tex] \boxed{\bf \dfrac{d+3}{d - 4} }[/tex]

________________________________

2. [tex] \bf \dfrac{ {m}^{2} + 2mn + {n}^{2} }{ {m}^{2} - {n}^{2} } [/tex]

By using identinty a² + 2ab + b² = (a + b)² in numerator and a² - n² = (a + b)(a - b) in denominator :

[tex] \tt : \implies \dfrac{(m+n)^{2}}{(m+n)(m-n)}[/tex]

[tex] \tt : \implies \dfrac{\cancel{(m+n)}(m+n)}{\cancel{(m+n)}(m-n)}[/tex]

[tex] \tt : \implies \dfrac{m+n}{m-n}[/tex]

Hence, answer is [tex] \boxed{\bf \dfrac{m+n}{m-n}}[/tex]

________________________________

3. [tex] \bf \dfrac{{x}^{2} + xy - 6{y}^{2}}{{x}^{2} - 3xy + 2{y}^{2}}[/tex]

By using splitting method in both numerator and denominator :

[tex] \tt : \implies \dfrac{{x}^{2} + 3xy - 2xy - 6{y}^{2}}{{x}^{2} - xy - 2xy + 2{y}^{2}}[/tex]

[tex] \tt : \implies \dfrac{x(x + 3y) - 2y(x + 3y)}{x(x - y) - 2y(x - y)}[/tex]

[tex] \tt : \implies \dfrac{\cancel{(x-2y)}(x + 3y)}{\cancel{(x-2y)}(x - y)}[/tex]

[tex] \tt : \implies \dfrac{x + 3y}{x - y}[/tex]

Hence, answer is [tex] \boxed{\bf \dfrac{x + 3y}{x - y}}[/tex]

Answer:

y=9x-4

OR

y-5=9(x-1)

(both are correct and equal)

Step-by-step explanation:

Parallel means slope is the same, so the slope of the equation should be 9.

Using point slope form:

[tex]y-5=9(x-1)[/tex]

Which would be:

[tex]y=9x-4[/tex]

in slope intercept form.

Answer:

5,172

Step-by-step explanation:

When figuring out a fraction of a number (especially of total things sold to find out the number of a certain thing purchased), remember that you are multiplying. So when finding 2/5 of 12,930, just multiply 12,930 by 2/5 (or, in decimal form, .4) and that will give you 5,172. Hope this helps!

Answer:

Step-by-step explanation:

Given the equation 2x-4y = 8 models the relationship between x and y

The rate of change of y with respect to x is known as the slope of the line.

The standard form of equation of a line is y = mx+c where;

m is the slope

c is the intercept

Rewrite the equation in its standard form as shown:

2x-4y = 8

-4y = -2x+8

-4y/-4 = -2x/-4 + 8/-4

y = 1/2 x -2

On comparison, the slope m is 1/2

Hence the rate of change of y with respect to x is 1/2

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

As, slope for printer A= 30-2/2-0

                                    = 30/2 = 15 pages per minute.

So, the rate of Printer A is 15 pages per minute.

Thus,

The rate for Printer B is greater than the rate for Printer A because the rate of 25 pages per minute is greater than the rate of 15 pages per minute for Printer A.

Answer:

See Below

Step-by-step explanation:

You want to find AB.

They give the equation for AB, BC, and AC

AC - BC = AB

substitute the equations

(30) - (8x + 3) = 6x + 8

30 - 8x - 3 = 6x + 8

27 - 8x = 6x + 8

     +8x  +8x

27 = 14x + 8

-8            -8

19 = 14x

19/14 = 14x/14

1.3571428 = x

0.1 = tenth

1.4 = x

Substitute x into the equation for AB

6(1.4) + 8

Step-by-step explanation:

Answer:

$400

Step-by-step explanation:

the seller would charge $400 if he or she wanted to sell laptops for their equilibrium price.

Demand and supply forces are balanced at an equilibrium price. Prices have the propensity to revert to this equilibrium unless certain demand or supply characteristics alter. When demand, supply, or both move or change, the equilibrium price will change.

neither a deficit nor a surplus exists unless a demand or supply determinant changes. When the price of a good or service changes and there is a shortage, this indicates that buyers want to purchase more than what producers are willing to sell.

Demand exceeds the supply in this situation, leaving customers unsatisfied. The opposite is true if a price shift results in a surplus, which indicates that customers wish to purchase fewer units than are being provided by producers.

In the given dataset, we can see that Demand and supply are equal at the price of laptops 400$.

Therefore, the seller would charge $400 if he or she wanted to sell laptops for their equilibrium price.

Answer:

5 drahms.

Step-by-step explanation:

From the question given above, the following data were obtained:

120 grains = 6 scruples

6 scruples = 2 drahms

300 grains (in drahms) =..?

From the above data,

120 grains = 6 scruples

6 scruples = 2 drahms

Therefore,

120 grains = 2 drahms

Thus, we can obtain 300 grains in drahms as follow:

120 grains = 2 drahms

Therefore,

300 grains = 300 grains × 2 drahms /120 grains

300 grains = (300 × 2)/120 drahms

300 grains = 5 drahms

Therefore, 300 grains is equivalent to 5 drahms.

Answer:

250 berries

Step-by-step explanation:

Berries : Oranges = 10 : 1

Product of means = 1*x = x

Product of extremes = 10 * 25 = 250

Product of means =  product of extremes
