We are given the two equations:

(1) -x=29-14y
(2) -9x=-19+14y

 

Multiply (1) by 9:

-9x = 261 – 126y

 

Subtract the two equations:

-9x = 261 – 126y

-

-9x=-19 + 14y

 

0 = 280 – 140y

140y = 280

y = 2

 

From (1):

-x = 29 – 14 (2)

x = -1

 

Answers:

x = -1

y = 2

Which of the following slopes of a line pass through points (1, -3) and (0, 2)?
Aloiza [94]

The slope of the line that passes through (1, -3) and (0, 2) is: B. m = -5.

<h3>What is the Slope of a Line?</h3>

Slope (m) = rise / run = change in y / change in x.

Given the points, (1, -3) and (0, 2):

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

Slope (m) = -5/1

Slope (m) = -5

Therefore, the slope of the line is: B. m = -5.

132=-6+3(1-5p) solve the equation
photoshop1234 [79]

Answer:

p=-9

Step-by-step explanation:

132=-6+3 (1-5p)

-6+3 (1-5p)=132

-6+3 (1-5p)+6=132+6

3(1-5p)=138

3(1-5p)/3=138/3

1-5p=46

1-5p-1=46-1

-5p=45

p=-9

Perimeter of quadrilateral ANCM = AN+NC+CM+MA

CM=AM = x in
Therefore, AN=NC = x in
In other words, all sides of the new quadrilateral are equal.

Perimeter (P) = 4x in

Now, Cos 45 = (x-6)/x =>0.7041 = (x-6)/x => 0.7041x=x-6 =>x= 6/(1-0.70741)
x= 20.5 in

Therefore, P=4*20.5 = 82 in
