Find the slope of the line through the points (-2,5) and (-6,-3)

Westkost [7]

Answer:

slope = 2

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 2, 5) and (x₂, y₂ ) = (- 6, - 3)

m = $\frac{-3-5}{-6+2}$ = $\frac{-8}{-4}$ = 2

$\frac{1}{3} (n + 15) = -2$

First, replace the numerator with the parentheses.
$\frac{n+15}{3} =-2$
Second, multiply both sides by 3.
$n + 15 = -2 * 3$
Third, multiply 2 × 3 to get 6.
$n + 15 = -6$
Fourth, take away 15 from each side.
$n = -6 - 15$
Fifth, simplify -6 - 15 to get -21.
$n = -21$

Answer: n = -21

The walnut Cove Ruritan Club sells hot dogs and drinks from a concession stand at the annual 4th of July parade. Carl bought 5 h

Naddik [55]

Answer:

The cost of one hot dog is $1.5 and the cost of one drink is $2.

Step-by-step explanation:

Let

<em>h</em> = the cost of a hog dog and <em>d</em><em> </em>= the cost of a drink

We know from the information given that:

Carl bought 5 hot dogs and 3 drinks and paid $13.50. This is equal to $5\cdot h +3\cdot d=13.50$

Susan purchased 2 hot dogs and 3 drinks and was charged $9.00. This is equal to $2\cdot h +3\cdot d=9.00$

So we have a system of equations

$5\cdot h +3\cdot d=13.50\\2\cdot h +3\cdot d=9.00$

We can solve by elimination as follows:

$\mathrm{Multiply\:}5h+3d=13.5\mathrm{\:by\:}2:\\10h+6d=27\\$

$\mathrm{Multiply\:}2h+3d=9\mathrm{\:by\:}5:\\10h+15d=45$

Subtract $10h+6d=27$ from $10h+15d=45$

$(10h+15d=45) -(10h+6d=27)=\\9d=18$

$\mathrm{Solve}\:9d=18\:\mathrm{for}\:d:\\d=2$

$\mathrm{For\:}10h+6d=27\mathrm{\:plug\:in\:}\quad \:d=2$

$\mathrm{Solve}\:10h+6\cdot \:2=27\:\mathrm{for}\:h:\\h=\frac{3}{2} = 1.5$

Therefore

<em>h</em> = $1.5 and <em>d</em><em> </em>= $2
