using the rise/run method the rise is 4 and the run is 2 so the slope should be 4/2

Answer:

y=2x+2

Step-by-step explanation:

step 1

Find the slope

The formula to calculate the slope between two points is equal to


m=\frac{y2-y1}{x2-x1}


we have


A(-4,-6)\ B(2,6)


Substitute the values


m=\frac{6+6}{2+4}


m=\frac{12}{6}=2


step 2

we know that

The equation of the line into slope intercept form is equal to

y=mx+b

we have

m=2


B(2,6)


substitute and solve for b

y=mx+b ------> 6=(2*2)+b

6=4+b

b=2

The equation of the line is equal to

y=2x+2

There are three cardinals, five sparrows and four finches near a bird feeder. If a sharp shunned hawk randomly selects one song
Hoochie [10]

Answer:

1/4

Step-by-step explanation:

The probability of it being a cardinal is the number of cardinals / the total number of possible birds the hawk could eat.

There are 3 + 5 + 4 = 12 total birds near the bird feeder.

There are 3 cardinals.

So the probability is 3/12 = 1/4 that the cardinal is eaten!

Assume that you live in a simple economy in which only three goods are produced and traded: Cashews, pecans and almonds. Suppose
oee [108]

Answer:

Step-by-step explanation:

The information given in the question can be represent in a table format for better understanding with the additional columns as follows:

Items          Weights Q₀         Prices P₀      Prices P₁        P₀Q₀        P₁Q₀

Cashew        1                        $12.50           $17.00        $12.50      $17.00

Pecans         1                         $4.00            $4.00         $4.00        $4.00

Almonds       1                         $5.50           $3.00          $5.50        $3.00

Total                                                                                 $22           $24

Can you say what happened to the overall "price level"?

The changes in overall price level can be a result of a condition termed as inflation rate

How might you construct a measure of the "change in price level"?

To construct a measure of the change in price level; we need to determine the consumer price index (CPI).

The consumer price index can be determined by using the relation:

=\mathbf{\dfrac{Sum \ of \ P_1Q_0}{Sum \ of  \ P_oQ_o}*100    }

= \mathbf{\dfrac{24}{22}*100    }

= 109.0%

consumer price index (CPI) is 109.0% ; This implies that there is a 9.9% inflation in the economy.

Burka [1]

Answer:    f'(1)=\dfrac{4}{2y+1}

<u>Step-by-step explanation:</u>

To find the tangent, you need to find the derivative with respect to x.

Then substitute x = 1 into the derivative.

Given:         0 = 2x² - xy - y²

Derivative:  0 = 4x - y' - 2yy'

Solve for y': 2yy' + y' = 4x

                   y'(2y + 1) = 4x

                   y'=\dfrac{4x}{2y+1}

\text{Substitute x = 1:}\quad y'(1)=\dfrac{4}{2y+1}

A. Let x = cheese and
y = chocolate
2x + y = 25
x + y = 20

B. Subtract the second equation from the first.
2x + y = 25
-(x + y = 20)
-—————
x = 5

Plug 5 back in to the second equation and solve for y.
x + y = 20
5 + y = 20
Subtract 5 from both sides.
y = 15
5 cheese and 15 chocolate

Used elimination method because coefficients on the y values were both 1 so it was easy to subtract the equations and eliminate the y variable.
