Answer:

11, 7, 44

Step-by-step explanation:

a+b+c = 62

a-4 = b

c = 4×a

I think you meant "diminished by four", right ?

=>

a + a-4 + 4×a = 62

6×a - 4 = 62

6×a = 66

a = 11

=>

b = 11 - 4 = 7

c = 4×11 = 44

The slope for is JK 1/3 , the slope of LK is -2 , the slope of ML is 2/5 , and the slope of MJ is 3/2 . Quadrilateral JKLM is not a parallelogram because neither pair of opposite sides is parallel

Further explanation:

Given vertices are:

J(−4, 1) , K(2, 3) , L(5, -3) , and M(0, −5) .

We have to find the slopes before concluding any result

The formula for slope is:

$m=\frac{y_2-y_1}{x_2-x_1}$

So:

<u>Slope of JK:</u>

$m_1=\frac{3-1}{2-(-4)}\\=\frac{2}{2+4}\\=\frac{2}{6}\\=\frac{1}{3}$

<u>Slope of LK:</u>

$m_2=\frac{-3-3}{5-2}\\=\frac{-6}{3}\\=-2$

<u>Slope of ML:</u>

$m_3=\frac{-3-(-5)}{5-0}\\=\frac{-3+5}{5}\\=\frac{2}{5}$

<u>Slope of MJ:</u>

$m_4=\frac{1-(-5)}{-4-0}\\=\frac{1+5}{-4}\\=\frac{6}{-4}\\=-\frac{3}{2}$

As the slopes of all sides are different, the given quadrilateral is not a parallelogram because in order for the quadrilateral to be a parallelogram the opposite sides have to be parallel i.e. have equal slopes and there are no sides with equal slopes.

Find the slope of the line shown on the graph to the right

damaskus [11]

Answer:

1

Step-by-step explanation:

We need two points to find the slope

( -1,0) and ( 2,3)

We can use the slope formula

m = ( y2-y1)/(x2-x1)

= ( 3-0)/(2 - -1)

= (3-0) / ( 2+1)

= 3/3

= 1

The slope is 1

Write an equation of the line that passes through the points (-9, 4) and (-10,8) in

MrRissso [65]

Answer:

y = -4x - 32

Step-by-step explanation:

First, find the slope using rise over run (y2 - y1) / (x2 - x1)

Plug in the points:

(y2 - y1) / (x2 - x1)

(8 - 4) / (-10 + 9)

4 / -1

= -4

So, the slope is -4. Plug in the slope and a point into y = mx + b, and solve for b:

y = mx + b

4 = -4(-9) + b

4 = 36 + b

-32 = b

Then, plug in the slope and y intercept into y = mx + b

y = -4x - 32 is the equation of the line
