Find the slope of the given points (3,4) and (7,-4)

mr Goodwill [35]

Answer:

Step-by-step explanation:

$\bold{slope\, (m)=\dfrac{change\ in\ Y}{change\ in\ X}=\dfrac{y_2-y_1}{x_2-x_1}}$

(3, 4) ⇒ x₁ = 3, y₁ = 4

(7, -4) ⇒ x₂ = 7, y₂ = -4

So the slope:

$\bold{m=\dfrac{-4-4}{7-3}=\dfrac{-8}4=-2}$

A positive integer is 2 less than another. If the sum of the reciprocal of the smaller and twice

valentinak56 [21]

Answer:

Step-by-step explanation:

Let x represent the smaller integer.

Let y represent the larger integer.

A positive integer is 2 less than another. It means that

y = x + 2

If the sum of the reciprocal of the smaller and twice the reciprocal of the larger is 11/15, it means that

1/x + 2/y = 11/15- - - - - - - - - - 1

Substituting y = x + 2 into equation 1, it becomes

1/x + 2/(x + 2) = 11/15

Considering the left hand side of the equation, it becomes

(x + 2 + 2x)/x(x + 2)

Therefore,

(3x + 2)/(x² + 2x) = 11/15

Cross multiplying, it becomes

15(3x + 2) = 11(x² + 2x)

45x + 30 = 11x² + 22x

11x² + 22x - 45x - 30 = 0

11x² - 23x - 30 = 0

11x² + 10x - 33x - 30 = 0

x(11x + 10) - 3(11 + 10) =℅0

(x - 3)(11x + 10) = 0

x - 3 = 0 or 11x + 10 = 0

x = 3 or x = - 10/11

Since it us a positive integer, the smaller integer is 3 and the larger integer is 3 + 2 = 5

PLZ HELP!!! I will name you brainliest!!!

velikii [3]

Answer:

x= 15 and y=4

Step-by-step explanation:

Let's start by finding y first using the basic proportionality

$\frac{12}{y}$ = $\frac{18}{6}$
12*6 = 18y
72 = 18y
y = 72/18
y= 4

now time to find x using the same way:

$\frac{12}{y}$ = $\frac{x}{5}$
$\frac{12}{4}$ = $\frac{x}{5}$
3 = $\frac{x}{5}$
x = 3*5
x= 15
